CVE-2026-25934

Name of the Vulnerable Software and Affected Versions go-git versions prior to 5.16.5

Description go-git is a Git implementation library written in Go. A flaw exists in how go-git handles the integrity verification of .pack and .idx files. Specifically, data integrity values were not properly verified, potentially allowing the consumption of corrupted files. This could lead to errors such as 'object not found' during operations involving fetched packfiles from Git servers or locally generated pack indexes. Packfiles contain checksums to ensure data integrity during client downloads. The incorrect verification process bypassed these checks.

Recommendations Update to version 5.16.5 or later.
