CVE-2026-44973 not yet assigned priority: Debian including 2 source packages (golang-github-go-git-go-billy, golang-github-go-git-go-billy-v6), 6 status rows across 4 suites (bookworm, forky, sid, trixie): open 6.
Billy is an interface filesystem abstraction for Go. Prior to 5.9.0, 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. This vulnerability is fixed in 5.9.0.
