GitPython before 3.1.60 contains a regular expression denial of service vulnerability in Actor.name_email_regex that processes commit author and committer fields. Attackers can craft a commit object with a malformed author field containing an unterminated angle bracket to cause quadratic backtracking, exhausting CPU resources for over two minutes per commit access.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - GitPython before 3.1.60 contains a regular expression denial of service vulnerability in
    Actor.name_email_regex that processes commit author and committer fields. Attackers can craft a commit
    object with a malformed author field containing an unterminated angle bracket to cause quadratic
    backtracking, exhausting CPU resources for over two minutes per commit access. (CVE-2026-87819)

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-2026:4191-1 advisory.

    - CVE-2026-87817: failure to properly validade the git directory location allows attackers to       impersonate the git directory using tracked files and execute arbitrary code by placing pre-commit hooks     in the       tracked hooks directory (bsc#1279905).
    - CVE-2026-87818: failure to restrict the `--no-index` option in the high-level diff API allows       attackers to read arbitrary filesystem paths as repository operands and create content-dependent Boolean     oracles       (bsc#1279906).
    - CVE-2026-87819: quadratic backtracking in the `Actor.name_email_regex` regular expression allows       attackers to cause CPU exhaustion and a DoS via a commit with a malformed author field (bsc#1279907).

Tenable has extracted the preceding description block directly from the SUSE security 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 3.1.60 contains a regular expression denial of service vulnerability in     Actor.name_email_regex that processes commit author and committer fields. Attackers can craft a commit     object with a malformed author field containing an unterminated angle bracket to cause quadratic     backtracking, exhausting CPU resources for over two minutes per commit access. (CVE-2026-87819)

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