CVE-2026-44740
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
v5are likely to be affected, users are recommended to upgrade to a supportedgo-billyversion.Credits
Thanks to @faran66 for finding and reporting this issue privately to the go-git project. 🙇
CVE-2026-44973
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-billyfor some level of isolation may inadvertently expose access to unintended filesystem locations.The
osfs.ChrootOSimplementation is notably affected by this vulnerability and is now deprecated inv5, removed atv6. Users are recommended to move on toosfs.BoundOSinstead:osfs.New(path, WithBoundOS()).Users requiring stronger security boundary enforcement are recommended to upgrade to
v6, where theosfsimplementation 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
v5are likely to be affected, users are recommended to upgrade to a supportedgo-billyversion.Credits
Thanks to @faran66 and @vnykmshr for finding and separately reporting this issue privately to the go-git project. 🙇
