CVE-2006-4548
HighSummary
e107 w wersji 0.75 i wcześniejszych nieprawidłowo unieważnia zmienne, gdy dane wejściowe zawierają parametr numeryczny, którego wartość odpowiada wartości skrótu parametru alfanumerycznego. To pozwala zdalnym atakującym na wykonanie dowolnego kodu PHP poprzez parametr tinyMCE_imglib_include w pliku e107_handlers/tiny_mce/plugins/ibrowser/ibrowser.php.
Risk Assessment
Podatność ta może prowadzić do zdalnego wykonania kodu, co stwarza poważne zagrożenie dla bezpieczeństwa systemu oraz danych użytkowników. Atakujący mogą wykorzystać tę lukę do przejęcia kontroli nad aplikacją.
Recommendation
Zaleca się aktualizację do najnowszej wersji e107, która zawiera poprawki bezpieczeństwa. Dodatkowo, warto monitorować i ograniczać dostęp do krytycznych plików aplikacji.

- 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)
e107 0.75 and earlier does not properly unset variables when the input data includes a numeric parameter with a value matching an alphanumeric parameter's hash value, which allows remote attackers to execute arbitrary PHP code via the tinyMCE_imglib_include image/jpeg parameter in e107_handlers/tiny_mce/plugins/ibrowser/ibrowser.php, as demonstrated by a multipart/form-data request. NOTE: it could be argued that this vulnerability is due to a bug in the unset PHP command (CVE-2006-3017) and the proper fix should be in PHP; if so, then this should not be treated as a vulnerability in e107.
