Summary
golang-github-go-git-go-git vulnerabilities
Details

Ionut Lalu discovered that go-git incorrectly handled certain specially crafted Git server responses. An attacker could possibly use this issue to cause a denial of service. (CVE-2023-49568, CVE-2025-21614)

Ionut Lalu discovered that go-git incorrectly handled file system paths when using the ChrootOS implementation. A remote attacker could possibly use this issue to perform a path traversal and create or modify arbitrary files, leading to remote code execution. (CVE-2023-49569)

It was discovered that go-git did not properly sanitize arguments when invoking git-upload-pack using the file transport protocol. An attacker could possibly use this issue to inject arbitrary flag values when interacting with local Git repositories. (CVE-2025-21613)

It was discovered that go-git did not properly verify integrity checks for pack and index files. An attacker could possibly use this issue to cause go-git to process corrupted repository data, resulting in unexpected errors or an incorrect repository state. (CVE-2026-25934)
