CVE-2026-2581
MediumSummary
Jest to podatność na niekontrolowane zużycie zasobów (CWE-400), która może prowadzić do ataku typu Denial of Service (DoS). W podatnych wersjach Undici, gdy włączona jest funkcja interceptors.deduplicate(), dane odpowiedzi dla zduplikowanych żądań mogą być gromadzone w pamięci dla dalszych handlerów.
Risk Assessment
Atakujący może wykorzystać tę podatność do przeciążenia systemu, co skutkuje jego niedostępnością dla użytkowników. Może to prowadzić do poważnych zakłóceń w działaniu usług.
Recommendation
Zaleca się aktualizację do najnowszej wersji Undici, w której ta podatność została naprawiona. Dodatkowo, warto rozważyć monitorowanie zużycia zasobów w celu wczesnego wykrywania potencjalnych ataków.
