CVE-2026-4867
HighSummary
Podatność CVE-2026-4867 dotyczy generowania błędnych wyrażeń regularnych w przypadku, gdy w jednym segmencie znajduje się trzy lub więcej parametrów oddzielonych znakiem innym niż kropka. Problem ten prowadzi do nakładania się grup przechwytywania i powoduje katastrofalne cofanie się.
Risk Assessment
Organizacje mogą być narażone na poważne problemy z wydajnością aplikacji z powodu nadmiernego cofania się, co może prowadzić do awarii lub spowolnienia działania systemu.
Recommendation
Zaleca się aktualizację do wersji [email protected] lub zastosowanie niestandardowych wyrażeń regularnych dla parametrów w definicjach tras, aby uniknąć problemów z wydajnością.

Original NVD description (English source)
Impact: A bad regular expression is generated any time you have three or more parameters within a single segment, separated by something that is not a period (.). For example, /:a-:b-:c or /:a-:b-:c-:d. The backtrack protection added in [email protected] only prevents ambiguity for two parameters. With three or more, the generated lookahead does not block single separator characters, so capture groups overlap and cause catastrophic backtracking. Patches: Upgrade to [email protected] Custom regex patterns in route definitions (e.g., /:a-:b([^-/]+)-:c([^-/]+)) are not affected because they override the default capture group. Workarounds: All versions can be patched by providing a custom regular expression for parameters after the first in a single segment. As long as the custom regular expression does not match the text before the parameter, you will be safe. For example, change /:a-:b-:c to /:a-:b([^-/]+)-:c([^-/]+). If paths cannot be rewritten and versions cannot be upg
