patch available.

  - moment is a JavaScript date library for parsing, validating, manipulating, and formatting dates. Affected
    versions of moment were found to use an inefficient parsing algorithm. Specifically using string-to-date
    parsing in moment (more specifically rfc2822 parsing, which is tried by default) has quadratic (N^2)
    complexity on specific inputs. Users may notice a noticeable slowdown is observed with inputs above 10k
    characters. Users who pass user-provided strings without sanity length checks to moment constructor are
    vulnerable to (Re)DoS attacks. The problem is patched in 2.29.4, the patch can be applied to all affected
    versions with minimal tweaking. Users are advised to upgrade. Users unable to upgrade should consider
    limiting date lengths accepted from user input. (CVE-2022-31129)

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