GitPython before 3.1.54 contains an incomplete denylist in unsafe_git_clone_options that omits --template, allowing attackers to achieve arbitrary command execution during clone operations. Attackers can supply --template pointing to a directory containing malicious post-checkout hooks that execute when git clones the repository.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:4072-1 advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - GitPython before 3.1.54 contains an incomplete denylist in unsafe_git_clone_options that omits --template,     allowing attackers to achieve arbitrary command execution during clone operations. Attackers can supply
    --template pointing to a directory containing malicious post-checkout hooks that execute when git clones     the repository. (CVE-2026-73623)

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