CVE-2026-64846

Nix versions prior to 2.35.0 contain a TOCTOU race in the LocalStore restore path: writeFile opens a path with O_TRUNC instead of enforcing FinalSymlink::DontFollow, allowing a malicious derivation (with recursive-nix enabled) to create or truncate an empty file outside the build sandbox with dae...

PT-2026-79064

Nix is a package manager for Linux and other Unix systems. Prior to 2.35.0, a malicious derivation executed with the recursive-nix experimental feature can exploit a time-of-check/time-of-use race involving final symlink handling in the LocalStore restore path. The race can cause writeFile to...

CVE-2026-29050

melange allows users to build apk packages using declarative pipelines. Starting in version 0.32.0 and prior to version 0.43.4, an attacker who can influence a melange configuration file — for example through pull-request-driven CI or build-as-a-service scenarios — could set pipeline.uses to a...

GHSA-98F2-W9H9-7FP9 melange has Path Traversal When Resolving External Pipelines via Unvalidated pipeline[].uses

Impact An attacker who can influence a melange configuration file — for example through pull-request-driven CI or build-as-a-service scenarios — could set pipeline.uses to a value containing ../ sequences or an absolute path. The Compiled.compilePipeline function in pkg/build/compile.go passed us...
