Oct 23, 2026odhcpd is the DHCPv6, DHCPv4, and router-advertisement server used by OpenWrt.CVE-2026-53920 · Other software · openwrt · reported by GitHubHigh 8.7
odhcpd is the DHCPv6, DHCPv4, and router-advertisement server used by OpenWrt. From version 17.01.0 to before version 25.12.3, odhcpd's DHCPv6 IA parser accepts an IA_NA or IA_PD option whose body is shorter than struct dhcpv6_ia_hdr, casts the option header to that full structure, and reads ia->iaid before proving that the IA body contains the IAID field. If an unauthenticated network-adjacent client places a zero-length or otherwise short IA option at the end of odhcpd's 8192-byte receive stack buffer, the IAID read crosses from data_buf into adjacent stack memory. The disclosed bytes are then reflected in the DHCPv6 reply IAID; prior ARM validation showed data_buf[8192:8196] disclosing the saved stack canary, and wider stack scans can leak ASLR-useful stack/process contents. This issue has been patched in version 25.12.3.

Oct 23, 2026odhcpd is the DHCPv6, DHCPv4, and router-advertisement server used by OpenWrt.CVE-2026-53918 · Other software · openwrt · reported by GitHubHigh 8.8
odhcpd is the DHCPv6, DHCPv4, and router-advertisement server used by OpenWrt. Prior to version 25.12, odhcpd's DHCPv6 IA handler keeps a per-message `first` lease pointer so multiple IA options in one message reuse the same Reconfigure authentication key. A DHCPv6 REQUEST from an adjacent-network client can make the first IA set `first`, then make a later same-IAID IA fail the on-link check and free that same lease, leaving `first` dangling. A following IA in the same packet allocates a new lease and copies `first->key`, producing a 16-byte heap-use-after-free read. ASan confirms the UAF; native tracing shows the packet shape can deterministically reclaim the freed lease as the destination allocation, producing a zeroed Reconfigure key copy. The validated impact is unauthenticated adjacent-network denial of service and DHCPv6 Reconfigure/ForceRenew key confusion. Arbitrary PC control is not proven for this UAF alone. This issue has been patched in version 25.12.

In the Linux kernel, the following vulnerability has been resolved: ibmveth: h_free logical LAN on open-fail after register ibmveth_open() registers the logical LAN, then allocates the RX buffer pools. A pool failure jumps to out_free_buffer_pools without h_free_logical_lan(), so PHYP still owns the buffer-list page when it is unmapped. request_irq() failure already issued the hypercall before taking the same label. Move that h_free to the shared post-register unwind so both paths deregister before the buffer list is unmapped.

In the Linux kernel, the following vulnerability has been resolved: openvswitch: fix soft lockup in the netlink flow dump A production compute node carrying a few thousand datapath flows hit a soft lockup inside a single netlink flow dump and panicked. ovs_flow_cmd_dump() calls ovs_flow_stats_get() for every flow it emits, and that releases stats->lock with spin_unlock_bh() once per CPU that has touched the flow. Every release is a local_bh_enable(), and each one runs the pending softirq backlog in the dumping thread's own context. The skb bounds the flows one callback emits, but not the softirq work it absorbs. On a CPU that carries the box's packet load the backlog refills as fast as it drains, so the dumping thread becomes that CPU's softirq engine. It never sleeps and it has no reschedule point, so under voluntary preemption nothing can take the CPU away from it: neither the ksoftirqd the kernel woke to take the work over, nor the stopper thread the softlockup detector dispatches to refresh its timestamp. Hold BH off across the whole callback instead, the way ctnetlink_dump_table() does, so the nested spin_unlock_bh() stop draining softirqs. The loop already runs under rcu

Oct 23, 2026In the Linux kernel, the following vulnerability has been resolved: namespace: keep covered mounts covered in OPEN_TREE_NAMESPACE open_tree(OPEN_TREE_NAMESPACCVE-2026-98988 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67High 8.8
In the Linux kernel, the following vulnerability has been resolved: namespace: keep covered mounts covered in OPEN_TREE_NAMESPACE open_tree(OPEN_TREE_NAMESPACE) creates a new mount namespace from a copy of the tree at the given path. The caller needs to be privileged over its current user namespace because the new mount namespace will be owned by it. It doesn't need to be privileged over the mount namespace the tree is copied from. An unprivileged user just needs to create a user namespace first. The copy follows the rules of a detached bind mount. Without AT_RECURSIVE only the mount itself is cloned and its children are left out. With AT_RECURSIVE unbindable mounts are skipped. Both is fine when the caller has privileges over the source mount namespace because it could unmount those mounts anyway. Not so for an unprivileged user in that mount namespace. For them a mount namespace copy is what unshare() does. copy_mnt_ns() copies everything including unbindable mounts and lock_mnt_tree() makes sure nothing can be unmounted in the copy. Nothing that was covered gets revealed. create_new_namespace() only does the locking and so the covered content is right there in the new mount

In the Linux kernel, the following vulnerability has been resolved: cxgb4/ch_ktls: disable softirqs around tid_list erases chcr_ktls_cpl_act_open_rpl() inserts into tid_list from the receive path using xa_insert_bh(). The array is shared by the adapter's connections and initialized with XA_FLAGS_LOCK_BH. However, chcr_ktls_dev_del() and the chcr_ktls_dev_add() error path use xa_erase(), which takes the XArray lock without disabling softirqs. When cleanup runs with softirqs enabled, a receive softirq for another connection on the same CPU can interrupt the erase and spin on the lock held by the interrupted task. Use xa_erase_bh() at both sites to match the insertion path.

In the Linux kernel, the following vulnerability has been resolved: perf/core: Check kernel access when kernel callchains are requested perf_event_open() currently gates perf_allow_kernel() only on !attr.exclude_kernel. However, users can still request kernel callchain collection with attr.exclude_callchain_kernel == 0 even when attr.exclude_kernel == 1. That still requires kernel profiling privilege, but the existing check does not enforce it. Update the permission check to call perf_allow_kernel() when either kernel sampling is requested or kernel callchains are requested. This keeps permission checks aligned with requested data and prevents unprivileged use of kernel callchain capture.

pghoard is a PostgreSQL backup daemon and restore tooling that stores backup data in cloud object stores. Prior to version 2.7.2, an incomplete path traversal fix in pghoard allows an attacker with write access to the backup object storage (such as S3, GCS, or Azure) to execute arbitrary file writes and directory creation outside the designated PostgreSQL data directory (pgdata). When a database administrator executes a restore operation (via pghoard_restore get-basebackup), a maliciously crafted delta backup manifest with path traversal sequences (e.g., ../../../../etc/cron.d/backdoor) will write arbitrary payloads to the host system. This issue has been patched in version 2.7.2.

Improper Certificate Validation vulnerability in the WebSocket streaming client in agentjido req_llm allows an on-path attacker to read and modify OpenAI WebSocket sessions, including the authorization bearer token, via a TLS certificate the client does not trust. ReqLLM.Streaming.WebSocketSession.Client.start/3 in lib/req_llm/streaming/web_socket_session/client.ex starts WebSockex without TLS options, and WebSockex defaults to insecure: true, which connects with verify: :verify_none. The option allowlist also drops any caller-supplied cacerts or ssl_options, so an application cannot turn verification on. The OpenAI Responses, Realtime, and Codex WebSocket paths reach this client and send the API key or OAuth access token in the authorization header. HTTP streaming through Finch and the HTTP/2 duplex session through Mint verify certificates and are not affected. This issue affects req_llm: from 1.9.0 before 1.29.0.

Part-DB is an open source inventory management system for electronic components. Prior to version 2.13.3, Part-DB builds the absolute URL of the password-reset link it emails to a user from the client-supplied HTTP Host header, with no trusted-host validation. An unauthenticated attacker who submits a forgot-password request for a known account while sending a spoofed Host header causes Part-DB to email that account a reset link whose hostname is attacker-controlled, while still embedding the genuine reset token. When the victim opens the link (or an automated inbound mail-security scanner dereferences it), the valid token is disclosed to the attacker, who replays it against the real instance to set a new password and take over the account. Because the seeded admin account can be targeted, this yields full pre-authentication administrative account takeover. This issue has been patched in version 2.13.3.

Part-DB is an open source inventory management system for electronic components. Prior to version 2.13.2, Part-DB contains a spreadsheet formula injection vulnerability in the part import/export workflow. An authenticated user with permission to import parts can import a CSV file containing formula-prefixed values, such as =1+1, into user-controlled part fields. When the affected part is later exported as an XLSX spreadsheet, Part-DB writes the attacker-controlled value using PhpSpreadsheet's setCellValue() method without neutralising spreadsheet formula characters. As a result, the exported XLSX file contains an executable spreadsheet formula cell rather than a plain text value. If another user exports and opens the spreadsheet, the formula may be evaluated by their spreadsheet software. This issue has been patched in version 2.13.2.

Part-DB is an open source inventory management system for electronic components. Prior to version 2.13.2, Part-DB allows authenticated API users to bypass the configured maximum attachment file size by uploading attachments through the API using base64-encoded file data. The application enforces the configured attachment size limit for normal browser-based file uploads, but the API base64 upload path does not apply the same size validation. As a result, an authenticated user with API access and permission to create attachments can upload files larger than the configured maximum attachment size, potentially exhausting disk space and causing a denial of service.

Part-DB is an open source inventory management system for electronic components. Prior to version 2.12.2, Part-DB renders BOM validation information messages using Twig's |raw filter. These messages include translated placeholders populated with user-controlled Part names. A user who can edit a Part name can store HTML markup in the Part name. When another user imports a BOM CSV referencing that Part ID, the malicious Part name is rendered as HTML in the victim's BOM validation result page. This results in a cross-user stored HTML injection issue. JavaScript execution appears to be blocked by the current Content Security Policy, but arbitrary HTML links, forms, images, and CSS-based UI elements can still be injected into a trusted Part-DB page.

Part-DB is an open source inventory management system for electronic components. Prior to version 2.12.1, the part attachment upload handler stores uploaded files under the web-served media directory using the client-supplied file extension, and its extension blocklist does not include phar. AttachmentSubmitHandler::renameBlacklistedExtensions() rewrites dangerous extensions (php, phtml, sh, cgi, py, js, html, htaccess, ...) to .txt, but phar is absent from the list, so a .phar file keeps its extension. Public attachments (the default) are written into public/media/, which is the Apache document root. The shipped Apache configuration routes .phar to PHP-FPM, so the stored file is executed as PHP on request. The per-attachment-type extension filter is empty by default and is not consulted by the upload handler in a way that blocks this, and a non-admin user in the default users group can create an attachment type with no filter and attach files to parts. Any authenticated user in the default users group uploads a .phar attachment to a part and fetches it under /media/, executing arbitrary PHP as the www-data web user. Ability to exploit depends on the webserver config, docker image

Part-DB is an open source inventory management system for electronic components. Prior to version 2.12.1, LogEntryExtraFormatter builds the HTML shown in the "Extra" column of the activity-log table (/log) and in element history tables. Every branch of LogEntryExtraFormatter::getInternalFormat() runs user-controlled strings through htmlspecialchars() before placing them into the HTML it returns — except the CollectionElementDeleted branch, which interpolates getOldName() (and getCollectionName()) into a sprintf() template with no escaping. The returned string is emitted by LogEntryExtraColumn::render() and inserted as raw HTML into the DataTables cell (the bundle does not escape column output; sibling columns call htmlspecialchars() themselves). CollectionElementDeleted.getOldName() is the name of a deleted collection sub-element — a part Parameter, Attachment, PartLot, Orderdetail, etc. — all freely set by any user with edit rights on the owning element. A low-privileged content editor can therefore store an HTML/script payload as the name of such a sub-element, delete it (which writes the log entry), and have that markup parsed as live DOM in the browser of a higher-privileged vi

The DHCPv4 option parser incorrectly calculates the length of the options data, causing it to read beyond the allocated buffer into adjacent heap memory. An attacker on the same network segment can send a crafted DHCP response to crash the daemon or corrupt its network configuration.

Oct 22, 2026A flaw was found in the OpenShift client oc.CVE-2026-115424 · Other software · Red Hat · reported by Red HatMedium 5.5
A flaw was found in the OpenShift client oc. When extracting container image layers with oc image extract, the application fails to properly sanitize symbolic and hard link targets pointing to absolute paths or to sibling directories of the extraction destination. An attacker who supplies a malicious container image can exploit this vulnerability by embedding links, and a chained file entry, that reference locations outside the intended extraction directory. This allows the attacker to write attacker-controlled content to arbitrary locations on the host filesystem with the privileges of the user running the command, potentially leading to file modification outside the destination directory.

Oct 22, 2026Authlib is a Python library which builds OAuth and OpenID Connect servers.CVE-2026-114620 · Other software · authlib · reported by GitHubMedium 5.4
Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to 1.9.0, Authlib's RFC 9101 JWTAuthenticationRequest passes the unauthenticated, client-controlled request_uri parameter to the abstract get_request_object() hook before applying a destination or registration policy; the hook itself performs no network request, while the documentation demonstrates an unrestricted HTTP fetch. In deployments whose integrator implements that hook as an unrestricted outbound fetch, a remote attacker who knows a valid public client identifier can make the authorization server request internal, link-local, or otherwise unintended URLs and can distinguish fetch outcomes through different error responses and timing. Deployments whose custom hook already applies a secure allowlist, destination controls, and retrieval limits are not affected. The JWTAuthenticationRequest implementation in authlib/oauth2/rfc9101/authorization_server.py forwards request_uri to get_request_object() before an application-approved retrieval policy accepts the destination. This issue is fixed in version 1.9.0.

Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to 1.9.0, OpenIDImplicitGrant.validate_authorization_request() checks the client-controlled raw request.payload.scope for openid after the parent grant has filtered allowed scopes into request.scope. A registered client permitted an ID token response type but not the openid scope can add openid to the request, obtain user consent, and receive a signed ID token containing the user's subject and allowed profile claims. Authorization code flow and deployments that allow openid for every client permitted an ID token response are not affected. In authlib/oidc/core/grants/implicit.py, OpenIDImplicitGrant.validate_authorization_request() checks request.payload.scope instead of the filtered request.scope. This issue is fixed in version 1.9.0.

Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to 1.9.0, the default RFC 7523 JWTBearerGrant.get_audiences() returns an empty list, causing JWTBearerGrant.verify_claims() to require only that an aud claim exists without matching the current authorization server. An attacker holding a legitimate assertion for another service can present it to a server that shares the signing key and uses the default grant, obtaining an access token across a trust boundary. Implementations that override get_audiences() with the server's valid audience identifiers are not affected. This issue is fixed in version 1.9.0.

Oct 22, 2026Authlib is a Python library which builds OAuth and OpenID Connect servers.CVE-2026-114617 · Other software · authlib · reported by GitHubMedium 4.2
Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to 1.9.0, OpenIDMixin.parse_id_token() reads the nonce_supported decision from the untrusted ID token being validated and sets the expected nonce to null when that claim is the JSON boolean false. In implicit and hybrid relying parties, or applications that directly accept externally supplied ID tokens, an attacker with a captured validly signed token can bypass the nonce-to-session binding and replay the victim's token into an attacker-controlled session. Plain authorization code flow is not affected, and the token must still pass signature, issuer, and audience validation. OpenIDMixin.parse_id_token() trusts nonce_supported in both authlib/integrations/base_client/sync_openid.py and authlib/integrations/base_client/async_openid.py to disable the expected nonce. This issue is fixed in version 1.9.0.

Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to 1.9.1, Authlib's OctKey.import_key() and HMAC signing and verification path accept zero-length key material. If an application's secret lookup can return an empty string or empty bytes, a remote attacker can compute the deterministic HS256, HS384, or HS512 signature for arbitrary token claims and have Authlib treat the token as authentic. This issue is fixed in version 1.9.1.

Authlib is a Python library which builds OAuth and OpenID Connect servers. From 1.3.1 until 1.9.0, OctKey.import_key() checks asymmetric-key markers only at byte zero while Authlib's PEM loaders accept leading whitespace, comments, or a byte-order mark. In deployments that use the documented mixed algorithm registry and already configure verification with PEM or certificate bytes containing such a prefix, an unauthenticated attacker who knows those same public-key bytes can use them as an HMAC secret and forge HS256 tokens with arbitrary identity or authorization claims. This is a bypass of the remediation for CVE-2024-37568. The module-level jwt object reaches OctKey.import_key() in authlib/jose/rfc7518/oct_key.py, where POSSIBLE_UNSAFE_KEYS fails to identify prefixed asymmetric key material. This issue is fixed in version 1.9.0.

Authlib is a Python library which builds OAuth and OpenID Connect servers. From 0.13 until 1.8.0, authlib.common.security.is_secure_transport() uses a textual prefix comparison for loopback HTTP exemptions, so a URL whose userinfo begins with a loopback host can be accepted even when its parsed host is an external non-loopback system. An external party able to supply a URL to OIDC RP-Initiated Logout registration, authorization-server metadata validation, or another call site can bypass the TLS-required guard and cause cleartext redirection or acceptance of cleartext endpoints. The issue does not bypass redirect URI exact matching and does not by itself forge tokens or authenticate users. The vulnerable authlib.common.security.is_secure_transport() implementation in authlib/common/security.py misinterprets the userinfo component before OIDC RP-Initiated Logout dynamic client registration and other consumers enforce transport security. This issue is fixed in version 1.8.0.

Unrestricted network access between execution contexts in KNIME Business Hub before version 1.19.0 allows an authenticated remote user to access open network ports on executors in different execution contexts. This only poses a security issue if the IP address of the attacked executor is know and there are open network ports that provided access without further authentication. By default no network ports are open. However, depending on the running workflows, ports may be opened and provide an attack surface. As a workaround, network policies can be created manually.
