Gitea validates a repository migration hostname against its network allow and block lists before invoking Git, but the Git subprocess independently resolves the hostname when connecting. An attacker who can start a migration and control the destination's DNS can change the address between validation and connection to reach a blocked internal address. The affected path is the Git clone operation; validation in the migration HTTP client's dialer does not protect the independently connecting Git subprocess.

Oct 6, 2026Twisted is an event-based framework for internet applications, supporting Python 3.6+.CVE-2026-106454 · Other software · twisted · reported by GitHubMedium 4.3
Twisted is an event-based framework for internet applications, supporting Python 3.6+. In 25.5.0 and earlier, wildcardToRegexp() in twisted/mail/imap4.py translates the IMAP asterisk and percent wildcards but passes all other characters from an authenticated client's LIST or LSUB pattern directly to re.compile(), allowing nested or otherwise expensive regular expression constructs to cause catastrophic backtracking when matched against mailbox names. Because Twisted uses a cooperative single-threaded reactor, the blocking match suspends all server input and output for the duration of the match. No fixed release is available as of this review.

Oct 6, 2026yawkat LZ4 Java provides LZ4 compression for Java.CVE-2026-106453 · Other software · yawkat · reported by GitHubMedium 5.3
yawkat LZ4 Java provides LZ4 compression for Java. Prior to 1.11.2, LZ4DecompressorWithLength uses getDecompressedLength to trust the four-byte decompressed-length header before validating the compressed input, allowing a five-byte attacker-supplied input whose header declares a large output size to request up to approximately 2 GiB and exhaust the JVM heap. Convenience overloads backed by LZ4FastDecompressor or LZ4SafeDecompressor allocate the untrusted size, while overloads that write to a caller-provided destination buffer are not affected because the caller controls the destination size. This issue is fixed in version 1.11.2.

yawkat LZ4 Java provides LZ4 compression for Java. Prior to 1.11.2, net.jpountz.lz4.LZ4BlockInputStream refill() validates that the compressedLen field in a legacy LZ4Block header is nonnegative but allocates a compressed-input buffer of that attacker-controlled size before reading payload data, allowing a header-only stream to request a near-2 GiB allocation and exhaust the JVM heap. Canonical writers emit raw blocks when compression is not smaller than the original block, but vulnerable readers accept non-canonical oversized compressed blocks. This issue is fixed in version 1.11.2.

Oct 6, 2026yawkat LZ4 Java provides LZ4 compression for Java.CVE-2026-106451 · Other software · yawkat · reported by GitHubHigh 7.3
yawkat LZ4 Java provides LZ4 compression for Java. From 1.7.0 until 1.11.4, net.jpountz.util.Native.load() uses File.createTempFile to create an exclusive temporary .lck file but derives the native-library path by removing the suffix, then FileOutputStream opens that predictable path without exclusive creation, allowing another local user with access to the same shared temporary directory to create or replace the library file before System.load() uses it. Successful exploitation depends on shared-directory permissions, host protections, and winning the race, and can execute native code as the victim; hardened systems may instead cause library loading to fail and fall back to Java implementations. Configurations using a system library, a private java.io.tmpdir, or Java-only implementations are not affected. This issue is fixed in version 1.11.4.

yawkat LZ4 Java provides LZ4 compression for Java. Prior to 1.11.4, net.jpountz.lz4.LZ4FrameInputStream readHeader() allocates two new 4 MiB block buffers whenever a maximum-block-size frame header is read, and the default concatenated-frame mode allows attacker-controlled streams containing many minimal empty frames to trigger roughly 8 MiB of allocation for every 11 input bytes. The stream produces no decompressed output while consuming CPU and garbage-collection time, so decompressed-size limits do not mitigate the issue; readSingleFrame mode is not affected. This issue is fixed in version 1.11.4.

yawkat LZ4 Java provides LZ4 compression for Java. Prior to 1.11.4, net.jpountz.lz4.LZ4BlockInputStream configured with stopOnEmptyBlock set to false handles each well-formed empty LZ4Block by recursively calling refill(), allowing a long sequence of empty blocks in an attacker-controlled compressed stream to exhaust the decoding thread's stack and throw StackOverflowError.

StableLib is a stable library of useful TypeScript and JavaScript code. Prior to 2.0.4, the @stablelib/cbor CBOR map decoding path creates ordinary JavaScript objects and assigns attacker-controlled keys with bracket assignment. A map key named __proto__ invokes the inherited prototype setter instead of creating an ordinary own property, allowing the decoded object's prototype to contain attacker-controlled authorization or feature-flag values. Downstream code that trusts normal property lookup or merges the decoded object can therefore make security-sensitive decisions using inherited attacker data. This issue is fixed in version 2.0.4.

Oct 6, 2026Handlebars provides the power necessary to let users build semantic templates.CVE-2026-106446 · Other software · handlebars-lang · reported by GitHubCritical 9.8
Handlebars provides the power necessary to let users build semantic templates. From 4.0.0 until 4.7.10, Handlebars.compile() and Handlebars.precompile() accept pre-parsed AST objects while validating only selected PathExpression, NumberLiteral, and BooleanLiteral values. This issue bypasses the AST validation introduced in version 4.7.9 for CVE-2026-33937. An attacker who can supply an object instead of a template string can place JavaScript expressions in unchecked values such as Program.blockParams.length, a non-PathExpression parameter depth, a non-string StringLiteral.value, or a non-string PathExpression.original. The compiler emits those values into generated JavaScript, causing code execution in the server process when compile output renders or wherever precompile output is loaded. Applications that pass only template strings are not affected. This issue is fixed in version 4.7.10.

Handlebars provides the power necessary to let users build semantic templates. From 3.0.0 until 4.7.10, Handlebars lookupProperty returns Function.prototype.constructor before applying the prototype-access deny list because constructor is an own property of Function.prototype. When an attacker can render a controlled template with allowProtoMethodsByDefault enabled and an accessible function in the template context, the template can traverse from that function through its prototype to Function.prototype and then obtain the Function constructor through the own-property bypass. This permits attacker-controlled JavaScript to execute with the server application's privileges. This issue is fixed in version 4.7.10.

Handlebars provides the power necessary to let users build semantic templates. From 4.0.0 until 4.7.10, Handlebars.precompile() uses quotedString() in lib/handlebars/compiler/code-gen.js to emit static template text into generated JavaScript without escaping sequences that terminate an enclosing HTML script element. When an application precompiles attacker-controlled template text and embeds the generated source directly in an inline script element, a closing script delimiter can end the element and cause following attacker-controlled markup to be parsed and executed. Ordinary server-side rendering and precompiled templates served as external JavaScript files are not affected. This issue is fixed in version 4.7.10.

This issue affects Apache log4net: from 1.2.9 before 3.5.0. Users are recommended to upgrade to version 3.5.0, which fixes the issue.

Oct 6, 2026Gitea validated the initial remote URL for push mirrors, wiki remote checks, and fetches of migrated pull request heads, but the subsequent raw Git operations fCVE-2026-104636 · Other software · Gitea · reported by 88ee5874-cf24-4952-aea0-31affedb7ff2High 7.5
Gitea validated the initial remote URL for push mirrors, wiki remote checks, and fetches of migrated pull request heads, but the subsequent raw Git operations followed HTTP redirects without revalidating the destination. A repository administrator using a policy-allowed endpoint that redirects could make Gitea's Git client send requests to an address that the outbound host policy would otherwise block. The impact depends on the configured policy and the internal services reachable from the server.

Oct 6, 2026Gitea Actions blocks the jobs of workflow runs from first-time fork pull request contributors until a maintainer approves the run.CVE-2026-104632 · Other software · Gitea · reported by 88ee5874-cf24-4952-aea0-31affedb7ff2High 8.8
Gitea Actions blocks the jobs of workflow runs from first-time fork pull request contributors until a maintainer approves the run. The rerun path only required a run to be finished and built the new attempt's jobs without considering the pending approval, so when a user with Actions write access cancelled a run that was awaiting approval and then re-ran it, the new jobs were created as waiting rather than blocked while the run still recorded that approval was required. Cancelling and re-running stale fork checks is a routine action that does not involve the approval control, so where Actions is enabled and a matching runner is registered, workflow code taken from the fork pull request head could run on the repository's runners without an explicit approval.

Oct 6, 2026A user who can open a fork pull request can place workflow content with a shared run-level concurrency group into a Gitea Actions run that is awaiting approval.CVE-2026-104626 · Other software · Gitea · reported by 88ee5874-cf24-4952-aea0-31affedb7ff2High 8.8
A user who can open a fork pull request can place workflow content with a shared run-level concurrency group into a Gitea Actions run that is awaiting approval. When a later run in that group cancels the blocked job, the run becomes terminal while still marked as needing approval. If a maintainer later approves the run, Gitea passed the already-cancelled job back through concurrency preparation, set it to waiting, and made it claimable by a matching runner, executing fork-controlled workflow code. Exploitation requires the maintainer's later approval action, Actions to be enabled, and a runner that accepts the repository's jobs.

Oct 6, 2026A flaw was found in SSSD.CVE-2026-104048 · Other software · Red Hat · reported by Red HatMedium 6.8
A flaw was found in SSSD. In trust-enabled identity management environments, SSSD evaluates Host-Based Access Control (HBAC) rules by stripping domain qualifiers and comparing only short usernames. An authenticated user in a trusted domain who shares the same username as an authorized local account can bypass access policies and gain unauthorized access to protected services or hosts.

Oct 6, 2026When a Gitea Actions run was inserted, older runs in the same workflow-level concurrency group were cancelled without checking whether the new run still needed CVE-2026-103670 · Other software · Gitea · reported by 88ee5874-cf24-4952-aea0-31affedb7ff2High 7.5
When a Gitea Actions run was inserted, older runs in the same workflow-level concurrency group were cancelled without checking whether the new run still needed approval. Because fork pull request runs are inserted under the base repository, a user who can open a pull request from a fork could cancel trusted in-progress runs that share a concurrency group with `cancel-in-progress` enabled, without approval and without running any code. On self-hosted runners this can interrupt deployments and leave partial state behind.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
