5.0 mediumCVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:HCVE-2026-34165
Medium (5.0) 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. From version 5.0.0 to before version 5.17.1, a vulnerability has been identified in which a maliciously crafted .idx file can cause asymmetric memory consumption, potentially exhausting available memory and resulting in a denial-of-service (DoS) condition. Exploitation requires write access to the local repository's .git directory, it order to create or alter existing .idx files. This issue has been patched in version 5.17.1.
