    Issue
    Impact Luxon's DateTime.fromRFC2822() has quadratic (N^2) complexity on some specific inputs. This causes a noticeable slowdown for inputs with lengths above 10k characters. Users providing untrusted data to this method are therefore vulnerable to (Re)DoS attacks. This is the same bug as Moment's https://github.com/moment/moment/security/advisories/GHSA-wc69-rhjr-hc9g Workarounds Limit the length of the input. References There is an excellent writeup of the same issue in Moment: https://github.com/moment/moment/pull/6015#issuecomment-1152961973 Details DateTime.fromRFC2822("(".repeat(500000)) takes a couple minutes to complete.

    Recommended action: Upgrade to 3.2.1, 2.5.2 or 1.28.1 by release line, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
