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.

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:4628-1 advisory.

    Security issues fixed:

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. (CVE-2026-71557)

Note that Nessus relies on the presence of the package as reported by the vendor.
