CVE ID: CVE-2026-87768 Distribution: DateTime-Lite Versions: before 0.8.1 MetaCPAN: https://metacpan.org/dist/DateTime-Lite VCS Repo: https://gitlab.com/deguest/DateTime-Lite DateTime::Lite versions before 0.8.1 for Perl allow CPU exhaustion via a per-day loop when adding seconds Description ----------- DateTime::Lite versions before 0.8.1 for Perl allow CPU exhaustion via a per-day loop when adding seconds. _normalize_leap_seconds crosses day boundaries one day at a time, so add(seconds => $n) on an object with a non-floating time zone takes about |$n|/86400 iterations, and nothing limits $n. The XS implementation and the pure-Perl fallback both have the loop. An attacker who controls the number of seconds added can keep the process busy for as long as they choose. Problem types ------------- - CWE-407 Inefficient Algorithmic Complexity Solutions --------- Upgrade to DateTime-Lite v0.8.1 or later. References ---------- https://metacpan.org/release/JDEGUEST/DateTime-Lite-v0.8.1/changes
