CVE-2026-45570: go-git: Improper single-quote escaping in go-git SSH transport
- Severity: critical (CVSS 9.6 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.4% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2026-05-27 · updated 2026-06-17
- Weakness: CWE-116
Description
go-git is an extensible git implementation library written in pure Go. Prior to 5.19.1 and 6.0.0-alpha.4, go-git's SSH transport constructs the remote exec command by wrapping the repository path in single quotes without escaping single quotes embedded inside the path. A repository path containing a single quote can therefore break out of the quoted region in the exec command and be appended as additional shell tokens. This vulnerability is fixed in 5.19.1 and 6.0.0-alpha.4.
Affected products
- go-git: before 5.19.1; 6.0.0-alpha1, 6.0.0-alpha2, 6.0.0-alpha3 — fixed in 5.19.1
How to fix
Upgrade to a fixed version: go-git 5.19.1. Check the vendor advisory for mitigations.
