CVE-2006-5159
HighSummary
Przepełnienie bufora na stosie w przeglądarce Mozilla Firefox umożliwia zdalnym atakującym wykonanie dowolnego kodu poprzez nieokreślone wektory związane z JavaScript. Badacze oraz dostawca zakwestionowali jednak powagę tej podatności, wskazując, że przedstawiony kod nie prowadził do wykonania kodu, a jedynie do awarii i zużycia zasobów systemowych.
Risk Assessment
Podatność ta może prowadzić do zdalnego wykonania kodu, co stwarza poważne zagrożenie dla bezpieczeństwa systemów korzystających z przeglądarki Firefox. Mimo to, istnieją wątpliwości co do rzeczywistego ryzyka, ponieważ kod nie wykazuje pełnej funkcjonalności ataku.
Recommendation
Zaleca się monitorowanie aktualizacji przeglądarki Firefox oraz stosowanie najnowszych poprawek bezpieczeństwa. Warto również rozważyć ograniczenie użycia JavaScript w środowiskach o podwyższonym ryzyku.

N-central is vulnerable to pre-auth remote code execution. This issue affects N-central before version 2026.3.1.14.
- CVE-2026-75816Critical
The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to Authentication Bypass to Account Takeover in all versions up to and including 3.29.12. The pre_update_value function lacks capability or ownership checks, and ActionPost::conditions_logic() short-circuits the current_user_can('edit_post') authorization gate when the post ID is non-numeric, allowing unauthenticated form submissions to be routed to arbitrary user records. This enables unauthenticated attackers to overwrite any user's email address, including an administrator's, and then use WordPress's native password-reset flow to take over the account.
- CVE-2026-16310Critical
The MemberDash plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to and including 1.8.5 via the 'id' parameter due to missing validation on a user-controlled key. This allows unauthenticated attackers to change the password of any WordPress user, including administrators, by supplying an arbitrary user ID during registration, and take over their account without any notification to the victim.

Original NVD description (English source)
Stack-based buffer overflow in Mozilla Firefox allows remote attackers to execute arbitrary code via unspecified vectors involving JavaScript. NOTE: the vendor and original researchers have released a follow-up comment disputing the severity of this issue, in which the researcher states that "we mentioned that there was a previously known Firefox vulnerability that could result in a stack overflow ending up in remote code execution. However, the code we presented did not in fact do this... I have not succeeded in making this code do anything more than cause a crash and eat up system resources"
