2.8 lowCVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:LCVE-2026-33762
Low (2.8) in go-git project go-git. EPSS 0.2% chance of exploitation in the next 30 days. Fixed in github.com/go-git/go-git/v5 5.17.1.
go-git is an extensible git implementation library written in pure Go. Prior to version 5.17.1, go-git’s index decoder for format version 4 fails to validate the path name prefix length before applying it to the previously decoded path name. A maliciously crafted index file can trigger an out-of-bounds slice operation, resulting in a runtime panic during normal index parsing. This issue only affects Git index format version 4. Earlier formats (go-git supports only v2 and v3) are not vulnerable to this issue. This issue has been patched in version 5.17.1.
