CriticalCVSS 9.1Exploitation Probability (EPSS)
Low risk13th percentile - higher than 13% of all known CVEs
Summary
Ustawienie bezimiennego ciasteczka z znakiem równości w wartości powodowało zasłonięcie innych ciasteczek. Problem występował nawet, gdy bezimienne ciasteczko było ustawione przez HTTP, a zasłonięte ciasteczko miało atrybut `Secure`. Podatność została naprawiona w Firefox 141, Firefox ESR 140.1, Thunderbird 141 oraz Thunderbird 140.1.
Risk Assessment
Zasłonięcie ciasteczek może prowadzić do nieautoryzowanego dostępu do danych użytkownika oraz naruszenia prywatności. Organizacje mogą być narażone na ataki typu session hijacking.
Recommendation
Zaleca się aktualizację przeglądarek Firefox i Thunderbird do najnowszych wersji, aby usunąć tę podatność. Należy również monitorować ustawienia ciasteczek w aplikacjach webowych.

- CVE-2026-7826Critical
A vulnerability in FalkorDB before 4.18.4 causes a heap-based out-of-bounds read in the BufferSerializerIOv2_ReadBuffer function. A remote attacker who can issue Redis replication commands (e.g., against an instance with no password) can send a crafted RDB stream with a sub-buffer length field exceeding the remaining buffer size. The only bounds check is an ASSERT(), which is compiled out in release builds, so memcpy() reads past the end of the heap allocation.
- CVE-2026-5759Critical
A double free and use-after-free vulnerability in the RdbLoadDeletedNodes function of the RDB graph decoders in FalkorDB before 4.18.1. A remote attacker who can issue Redis replication commands can send a crafted RDB stream where the deleted-nodes buffer length is not a multiple of sizeof(NodeID). The length check relies on ASSERT(), which is compiled out in release builds, so the function continues after freeing the buffer, reading it and freeing it a second time.

Original NVD description (English source)
Setting a nameless cookie with an equals sign in the value shadowed other cookies. Even if the nameless cookie was set over HTTP and the shadowed cookie included the `Secure` attribute. This vulnerability was fixed in Firefox 141, Firefox ESR 140.1, Thunderbird 141, and Thunderbird 140.1.
