Name of the Vulnerable Software and Affected Versions go-git versions prior to v5.11

Description A denial of service (DoS) vulnerability was discovered in go-git. This vulnerability allows an attacker to perform denial of service attacks by providing specially crafted responses from a Git server, which triggers resource exhaustion in go-git clients. Applications using only the in-memory filesystem supported by go-git are not affected by this vulnerability. This is a go-git implementation issue and does not affect the upstream git cli.

Recommendations For go-git versions prior to v5.11, upgrade to v5.11 to mitigate this vulnerability. As a temporary workaround, consider limiting the use of go-git to only trustworthy Git servers if upgrading to v5.11 is not possible.
