CVE-2026-4283
CriticalSummary
Wtyczka WP DSGVO Tools (GDPR) dla WordPressa jest podatna na nieautoryzowane usuwanie kont we wszystkich wersjach do i włącznie z 3.1.38. Problem wynika z akcji AJAX `super-unsubscribe`, która akceptuje parametr `process_now` od nieautoryzowanych użytkowników, omijając proces potwierdzenia e-mailem i natychmiastowo wywołując nieodwracalną anonimizację konta.
Risk Assessment
Nieautoryzowani atakujący mogą trwale zniszczyć konta użytkowników, co prowadzi do utraty danych i potencjalnych problemów z zgodnością z regulacjami prawnymi. To stwarza poważne ryzyko dla bezpieczeństwa danych w organizacji.
Recommendation
Zaleca się aktualizację wtyczki do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, warto rozważyć ograniczenie dostępu do akcji AJAX oraz wprowadzenie dodatkowych mechanizmów weryfikacji użytkowników.

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.

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)
The WP DSGVO Tools (GDPR) plugin for WordPress is vulnerable to unauthorized account destruction in all versions up to, and including, 3.1.38. This is due to the `super-unsubscribe` AJAX action accepting a `process_now` parameter from unauthenticated users, which bypasses the intended email-confirmation flow and immediately triggers irreversible account anonymization. This makes it possible for unauthenticated attackers to permanently destroy any non-administrator user account (password randomized, username/email overwritten, roles stripped, comments anonymized, sensitive usermeta wiped) by submitting the victim's email address with `process_now=1`. The nonce required for the request is publicly available on any page containing the `[unsubscribe_form]` shortcode.
