go-billy: Lack of depth and cycle detection in symlink resolution may lead to infinite loops and resource exhaustion

CVE-2026-44740 / GHSA-m3xc-h892-ggx6

More information

Details

Impact

Multiple components may improperly handle crafted or malformed input, resulting in panics, infinite loops, uncontrolled recursion, or excessive resource consumption.

These issues arise from insufficient validation and missing safety mechanisms such as cycle detection, recursion limits, or defensive handling of unexpected states when processing untrusted repository data and filesystem structures.

Patches

Users should upgrade to a patched version in order to mitigate this vulnerability. Versions prior to v5 are likely to be affected, users are recommended to upgrade to a supported go-billy version.

go-billy has path traversal vulnerabilities

CVE-2026-44973 / GHSA-qw64-3x98-g7q2

More information

Details

Impact

Multiple path traversal issues exist across different components of go-billy. Insufficient path sanitization and boundary enforcement may allow crafted paths (e.g., using ..) to escape intended base directories.

While go-billy was not originally designed to provide a strong security boundary, some of these issues were inconsistent across some of the built-in implementations. This results in scenarios where applications relying on go-billy for some level of isolation may inadvertently expose access to unintended filesystem locations.

The osfs.ChrootOS implementation is notably affected by this vulnerability and is now deprecated in v5, removed at v6. Users are recommended to move on to osfs.BoundOS instead: osfs.New(path, WithBoundOS()).

Users requiring stronger security boundary enforcement are recommended to upgrade to v6, where the osfs implementation are backed by the traversal-resistant primitive os.Root.

Patches

Users should upgrade to a patched version in order to mitigate this vulnerability. Versions prior to v5 are likely to be affected, users are recommended to upgrade to a supported go-billy version.
