CVE-2006-4447
HighSummary
X.Org i XFree86, w tym libX11, xdm, xf86dga, xinit, xload, xtrans i xterm, nie sprawdzają wartości zwracanych przez wywołania setuid i seteuid podczas próby obniżenia uprawnień. Może to pozwolić lokalnym użytkownikom na uzyskanie wyższych uprawnień poprzez spowodowanie niepowodzenia tych wywołań, na przykład przez przekroczenie limitu ulimit.
Risk Assessment
Organizacja może być narażona na nieautoryzowany dostęp do systemu, co może prowadzić do eskalacji uprawnień przez lokalnych użytkowników. To stwarza poważne zagrożenie dla integralności i bezpieczeństwa systemów.
Recommendation
Zaleca się aktualizację do najnowszej wersji X.Org lub XFree86, która zawiera poprawki dotyczące sprawdzania wartości zwracanych przez wywołania setuid i seteuid. Dodatkowo, warto przeprowadzić audyt uprawnień użytkowników w systemie.

- 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.

Original NVD description (English source)
X.Org and XFree86, including libX11, xdm, xf86dga, xinit, xload, xtrans, and xterm, does not check the return values for setuid and seteuid calls when attempting to drop privileges, which might allow local users to gain privileges by causing those calls to fail, such as by exceeding a ulimit.
