go-git's improper parsing of specially crafted objects may lead to inconsistent interpretation compared to upstream Git

CVE-2026-45022 / GHSA-389r-gv7p-r3rp

More information

Details

Impact

go-git may parse malformed Git objects in a way that differs from upstream Git. When commit or tag objects contain ambiguous or malformed headers, go-git’s decoded representation may expose values differently from how Git itself would interpret or reject the same object.

Additionally, go-git’s commit signing and verification logic operates over commit data reconstructed from go-git’s parsed representation rather than the original raw object bytes. As a result, go-git may sign or verify a commit payload that is not byte-for-byte equivalent to the object stored in the repository.

This can cause a signature to appear valid for a commit whose displayed or effective metadata differs from the object that was intended to be signed.

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-git version.

🔍 Dependency Review

github.com/go-git/go-git/v5 v5.18.0 -> v5.19.0 — ✅ Safe

Summary

  • Scope: Minor update within the same major version (v5).
  • Impact: No breaking API changes are called out between v5.18.0 and v5.19.0. The update includes dependency bumps (notably go-billy and sha1cd) and bug fixes/perf improvements.
  • Code changes in this repo: None required.

References

Notes

  • This upgrade pulls in newer go-billy (v5.9.0) and pjbgf/sha1cd (v0.6.0), both backward-compatible for typical go-git usage.

Suggested actions

  • No code edits needed. Run your test suite to validate behavior in your Git-related features (clone/fetch/pull/SSH transports, submodules, packfile handling).
github.com/go-git/go-billy/v5 v5.8.0 -> v5.9.0 — ✅ Safe

Summary

  • Scope: Minor update in the filesystem abstraction used by go-git.
  • Impact: No breaking API changes are called out for v5.9.0. Changes are primarily internal fixes and enhancements used by go-git.
  • Code changes in this repo: None required (the project does not appear to use go-billy directly).

References

Suggested actions

  • None.
github.com/pjbgf/sha1cd v0.3.2 -> v0.6.0 — ✅ Safe

Summary

  • Scope: Indirect dependency (used by go-git for SHA-1 collision detection).
  • Impact: No repo code uses this package directly. Updates include internal improvements; public surface remains compatible for transitive usage.
  • Code changes in this repo: None required.

References

Suggested actions

  • None.
github.com/cyphar/filepath-securejoin v0.6.0 -> v0.6.1 — ✅ Safe
