Oct 21, 2026Storybook is a frontend workshop for building user interface components and pages in isolation.CVE-2026-114125 · Other software · storybookjs · reported by GitHubHigh 8.6
Storybook is a frontend workshop for building user interface components and pages in isolation. From 8.0.0 until 8.6.19, 9.1.21, 10.6.2, and 11.0.0-alpha.6, a malicious website can interact with the preview of a running Storybook development server. Insufficient iframe embedding and message-origin restrictions can allow attacker-controlled events to reach the running preview. A developer must visit the malicious website and interact with the injected interface. The attack can cause unauthorized changes to story files and, if a changed file is later executed by a local runtime, arbitrary code execution with the developer's privileges. This issue is fixed in 8.6.19, 9.1.21, 10.6.2, and 11.0.0-alpha.6.

Oct 21, 2026When package management is enabled, Pulsar Functions, Sources and Sinks can be registered or updated from a package stored in the Pulsar Packages Management SerCVE-2026-105930 · Websites & servers · Apache Software Foundation · reported by security@apache.orgMedium 6
When package management is enabled, Pulsar Functions, Sources and Sinks can be registered or updated from a package stored in the Pulsar Packages Management Service by supplying a package URL. The Pulsar Functions worker authorized these requests only against the namespace in which the component was being registered or updated. It did not check whether the requesting user was permitted to access packages in the namespace that the package URL refers to, and it retrieved the package from the broker using the worker's own credentials. The permission check of the Packages Management Service was therefore applied to the worker's identity instead of the requesting user's. Package URLs of transform functions supplied when registering or updating a sink were handled in the same way. An authenticated user who is permitted to register or update functions, sources or sinks in any namespace of their own tenant could use this to obtain the contents of a package stored in a namespace of another tenant, without having the packages permission on that namespace. The impact is limited to disclosure of package contents, which may include application code, business logic or embedded credentials. The

The Apache Pulsar WebSocket service allows a WebSocket consumer to configure a dead letter policy through query parameters of the consumer endpoint, including the deadLetterTopic parameter that names the topic to which messages are written after the maximum number of redeliveries is exceeded. When authorization is enabled, the WebSocket service checks only that the connecting user holds the CONSUME permission on the subscribed topic. It does not check whether the user holds the PRODUCE permission on the topic named in deadLetterTopic. The dead letter messages are then written by the WebSocket service using its own broker client identity rather than the identity of the connecting user. As a result, an authenticated user who holds the CONSUME permission on at least one topic can cause messages to be written to a topic of their choosing in any existing namespace, including namespaces belonging to other tenants, provided the role used by the WebSocket service to connect to the brokers is authorized to produce to that topic and the topic accepts a producer that registers no schema. The dead letter producer created by the WebSocket service registers no schema, so it is rejected when the

The Pulsar broker serves two schema commands on its binary protocol: GetSchema, which returns the schema registered for a topic, and GetOrCreateSchema, which registers a new schema version for an existing topic. The broker handled both commands after checking only that the client connection was authenticated. Unlike the broker's other topic commands, such as those for creating producers and consumers or for looking up topics, these two commands did not check whether the authenticated client was authorized for the target topic. The Pulsar REST API endpoints for schemas were not affected. An authenticated client without any permission on the target topic, namespace or tenant could use these commands to: - read the schema registered for a topic in another namespace or tenant, disclosing the schema definition such as record field names and types. Message payloads are not disclosed. - register a new schema version on an existing topic in another namespace or tenant. The topic's schema compatibility and schema auto-update policies still apply. The issue does not allow message data to be read or modified, but a registered schema version can cause legitimate producers and consumers of th

Oct 21, 2026Apache Pulsar's MultiRolesTokenAuthorizationProvider authorizes a client with all roles listed in a claim of its JSON Web Token (JWT).CVE-2026-105869 · Websites & servers · Apache Software Foundation · reported by security@apache.orgCritical 9.2
Apache Pulsar's MultiRolesTokenAuthorizationProvider authorizes a client with all roles listed in a claim of its JSON Web Token (JWT). The provider is intended for use with token authentication, which verifies the token before authorization. The provider did not verify the token itself: it parsed the token's claims with the signature removed and trusted that authentication had already checked it. When authentication and authorization are enabled with a non-empty anonymousUserRole setting, some HTTP requests whose credentials fail authentication are not rejected, but are handled as requests of the anonymous user role. For the broker's HTTP endpoints, such as the admin REST API, this fallback applies to requests that do not name an authentication method and requires strictAuthMethod to be false (the default) where that setting is available. For the WebSocket API, failed credentials can also fall back to the anonymous user role; this path does not enforce strictAuthMethod. The authentication data kept for such a request still contained the request's Authorization header. MultiRolesTokenAuthorizationProvider then read the bearer token from that header without verifying its signature a

A vulnerability in the IPv4 packet processing functionality of Cisco IOS XR Software that affects Cisco ASR 9000 and 9900 Series Aggregation Services Routers as well as Cisco ASR 9902 and 9903 Compact High-Performance Routers could allow an unauthenticated, remote attacker to cause network processor (NP) errors, resulting in a line card reset or shutdown and a denial of service (DoS) condition.  This vulnerability is due to the incorrect handling of crafted IPv4 packets that are received on an affected line card interface and processed as for-us traffic. The issue can result in an NP reset, causing traffic loss on the affected line card while it recovers. Under repeated reset conditions, the network processor may enter a persistent shutdown state, in which case an explicit line card reload may be required to restore traffic. The vulnerability is within the IPv4 packet-processing path. Transit IPv4 traffic does not trigger this issue and IPv6 traffic cannot trigger it.

Oct 21, 2026A vulnerability in the interprocess communication (IPC) channel of the Secure Firewall Posture module in Cisco Secure Client could allow an authenticated, localCVE-2026-76462 · Network & remote access · Cisco · reported by psirt@cisco.comMedium 5.5
A vulnerability in the interprocess communication (IPC) channel of the Secure Firewall Posture module in Cisco Secure Client could allow an authenticated, local attacker to elevate privileges on an affected device. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a series of crafted IPC messages to a local socket. A successful exploit could allow the attacker to perform limited file write operations on the filesystem with SYSTEM or root privileges. Although this vulnerability affects the Secure Firewall Posture module in Cisco Secure Client on Windows, macOS, and Linux operating systems, this vulnerability could be used to obtain full root privileges on macOS and Linux. For that reason Cisco has assigned this security advisory a Security Impact Rating (SIR) of High rather than Medium as the score indicates.

D365 F&O MCP Server is a Model Context Protocol server for querying Dynamics 365 Finance & Operations X++ code and metadata. Prior to version 1.11.0, the officially documented Azure one-click deployment uses infrastructure/azuredeploy.json and infrastructure/main.bicep to default the apiKey parameter to an empty string and pass it to the App Service API_KEY setting. With API_KEY unset or empty, src/middleware/apiKeyAuth.ts passes requests through without authentication, while src/index.ts binds the HTTP listener to 0.0.0.0 by default. If the deployer leaves the optional key blank and does not add separate network restrictions or upstream authentication, the resulting public App Service allows unauthenticated JSON-RPC tools/call requests to /mcp. The deployment's MCP_SERVER_MODE=read-only setting does not prevent anonymous access to read/search tools, including search, get_object_info, batch_get_info, extension_info, security_info, find_references, and find_event_handlers, exposing indexed proprietary X++ source snippets and metadata. Exposed information can include business logic, extension and event-handler wiring, security-role and privilege structure, and labels originally index
