CVE-2026-71557 | BDVDB-2026-356380 Detail
go-gitgo-git
Description#
go-git is an extensible git implementation library written in pure Go. Prior to 5.19.2 and 6.0.0-alpha.5, reference names are not sanitized before being used to construct on-disk paths under the reference storage directory, so a maliciously crafted reference name (for example containing directory-traversal sequences) can cause go-git to write files outside the intended reference storage directory. Versions 5.19.2 and 6.0.0-alpha.5 fix the issue.
Impact#
Per CVSS v3.1: confidentiality impact none, integrity impact high, availability impact low. Attack vector: network.
Weaknesses#
- CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
