(CVE-2023-49569)\n\nIt was discovered that go-git did not properly sanitize arguments when\ninvoking git-upload-pack using the file transport protocol. An attacker\ncould possibly use this issue to inject arbitrary flag values when\ninteracting with local Git repositories. (CVE-2025-21613)\n\nIt was discovered that go-git did not properly verify integrity checks for\npack and index files. An attacker could possibly use this issue to cause\ngo-git to process corrupted repository data, resulting in unexpected errors\nor an incorrect repository state.
