In versions 4.2.0.Final up to but not including 4.2.16.Final, and 4.1.0.Final up to but not including 4.1.135, the HAProxyMessageDecoder in Netty's codec-haproxy module performs protocol version detection by...

GHSA-HG5R-VQ93-9FV6 Gitea Actions Artifacts V4 signed URL HMAC ambiguity allows cross-repository artifact read and cross-task upload-state write

Summary Gitea Actions Artifacts V4 signed upload/download URLs can be rewritten to access a different running task and repository context while preserving the original HMAC signature. An attacker with permission to run a Gitea Actions job can turn a signed URL for an attacker-controlled artifact...

GHSA-XVCM-6775-5M9R Immutable: Hash-collision algorithmic complexity denial of service in Immutable.Map/Set

Summary Immutable.Map and Immutable.Set keep keys that share the same 32-bit hash in a collision bucket that is scanned linearly. The string hash is public and deterministic, so an attacker who controls the keys inserted into a Map can craft many keys that all collide, degrading insertion and...

GHSA-C6W9-5G5J-JH2P Directus: Authorization-dependent response served from unsegmented cache key

Summary When response caching is enabled CACHEENABLED=true, the cache-key derivation in api/src/utils/get-cache-key.ts includes only version, path, query, and accountability.user plus a conditional ip. Authorization context beyond user share, role, roles, admin, app, policies is not part of the...

GHSA-2HM2-HC3V-44H9 Mistune toc / TableOfContents directive: heading IDs use predictable `toc_N` numbering with no slugification, allowing collision with attacker-controlled `id="toc_N"` content

Summary Type: Predictable identifier generation. The toc plugin and TableOfContents directive both default to generating heading IDs of the form toc1, toc2, toc3, ... with no input-derived component. An attacker who can place a heading anywhere in the document can predict which tocN ID it will...

CVE-2026-16158 @fastify/reply-from vulnerable to cross-upstream request routing via URL cache key collision

Impact: @fastify/reply-from versions from 8.3.1 up to but not including 12.6.4 build the internal URL cache key by concatenating the destination and source path without a delimiter. Different destination and source pairs can therefore produce the same key while resolving to different upstream URL...
