A vulnerability has been found in mlrun up to 1.12.0-rc3. This impacts the function mlrun.utils.helpers.calculatedataframehash of the file mlrun/utils/helpers.py of the component DataFrame Hash Handler. The manipulation leads to use of weak hash. The attack can only be performed from a local...

Improper Encoding or Escaping of Output

Overview next is a react framework. Affected versions of this package are vulnerable to Improper Encoding or Escaping of Output via the IncrementalCache.generateCacheKey function in next/dist/server/lib/incremental-cache. An attacker can make a server-side fetch return a cached response body from...

Incorrect Implementation of Authentication Algorithm

Overview Affected versions of this package are vulnerable to Incorrect Implementation of Authentication Algorithm due to lossy ISO-8859-1 encoding in the digest hash computation. An attacker can log in as a user with a non-Latin-1 password by supplying a collision password that replaces each...

GHSA-2FVJ-HGJ9-J2GR Eclipse Jetty Digest Authentication: ISO-8859-1 lossy encoding allows authentication bypass via character substitution

Summary The DigestAuthentication.apply method in Jetty's HTTP client uses getBytesStandardCharsets.ISO88591 at three locations lines 171, 179, 196 to compute Digest auth response hashes. ISO-8859-1 silently replaces any character above U+00FF Chinese, Japanese, Cyrillic, Arabic, Emoji, etc. with...

PT-2026-63532

Name of the Vulnerable Software and Affected Versions Eclipse Jetty affected versions not specified Description The Digest authentication server-side component and the DigestAuthentication.apply method in the HTTP client use ISO-8859-1 encoding to process passwords. Because ISO-8859-1 cannot...

CVE-2026-55851 Netty codec-haproxy: Signed-Byte Sentinel Collision in HAProxyMessageDecoder Leads to Unbounded Memory Exhaustion

Netty is a network application framework for development of protocol servers and clients. 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...
