CVE-2026-71557
go-git: Malicious reference names may modify files outside the reference storage
Published Aug 7, 2026
CVSS 3.1 · 6.3 Medium
EPSS < 1%
KEV · Not listed
Description
go-git is an extensible git implementation library written in pure Go. Prior to 5.19.2 and 6.0.0-alpha.5, reference names are not sanitized before being used to construct on-disk paths under the reference storage directory, so a maliciously crafted reference name (for example containing directory-traversal sequences) can cause go-git to write files outside the intended reference storage directory. Versions 5.19.2 and 6.0.0-alpha.5 fix the issue.
