Description Jon Weiser 2026-09-23 15:31:35 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

go-git is an extensible git implementation library written in pure Go. Prior to 5.19.2 and 6.0.0-alpha.5, worktree operations (including checkout, status, and add) resolve symbolic links inside the working tree without confining resolution to the worktree boundary, so a maliciously crafted repository containing a symlink can cause go-git to read from or write to files outside the intended working directory when the repository is cloned and its worktree operations are used. Versions 5.19.2 and 6.0.0-alpha.5.
Comment 1 Marcus Burghardt 2026-09-25 10:20:19 UTC 
complyctl does not depend on github.com/go-git/go-git (neither directly nor transitively). This module does not appear in go.mod or vendor/modules.txt.

This dependency was removed in:
  PR #381: feat(cli)!: complyctl redesign (#381)
