GitHub Vulnerability Alerts
CVE-2026-25934
Impact
A vulnerability was discovered in
go-gitwhereby data integrity values for.packand.idxfiles were not properly verified. This resulted ingo-gitpotentially consuming corrupted files, which would likely result in unexpected errors such asobject not found.For context, clients fetch
packfilesfrom upstream Git servers. Those files contain a checksum of their contents, so that clients can perform integrity checks before consuming it. The pack indexes (.idx) are generated locally bygo-git, or thegitcli, when new.packfiles are received and processed. The integrity checks for both files were not being verified correctly.Note that the lack of verification of the packfile checksum has no impact on the trust relationship between the client and server, which is enforced based on the protocol being used (e.g. TLS in the case of
https://or known hosts forssh://). In other words, the packfile checksum verification does not provide any security benefits when connecting to a malicious or compromised Git server.Patches
Users should upgrade to
v5.16.5, or the latestv6pseudo-version, in order to mitigate this vulnerability.Workarounds
In case updating to a fixed version of
go-gitis not possible, users can run git fsck from thegitcli to check for data corruption on a given repository.Credit
