CVE-2022-31129

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.
