CVE-2006-6731
HighSummary
Wielokrotne przepełnienia bufora w Sun Java Development Kit (JDK) i Java Runtime Environment (JRE) 5.0 Update 7 oraz wcześniejszych wersjach, a także w Java System Development Kit (SDK) i JRE 1.4.2_12 oraz wcześniejszych wersjach 1.4.x, umożliwiają atakującym tworzenie apletów Java, które mogą odczytywać, zapisywać lub wykonywać lokalne pliki. Problemy te są związane z przepełnieniami całkowitymi oraz niewłaściwym przetwarzaniem niektórych wartości ujemnych.
Risk Assessment
Podatność ta stwarza poważne zagrożenie dla bezpieczeństwa, ponieważ umożliwia atakującym dostęp do lokalnych plików, co może prowadzić do kradzieży danych lub złośliwego oprogramowania. Organizacje powinny być świadome ryzyka związanego z używaniem nieaktualnych wersji JDK i JRE.
Recommendation
Zaleca się aktualizację do najnowszej wersji Sun Java Development Kit i Java Runtime Environment, aby zminimalizować ryzyko związane z tą podatnością. Dodatkowo, należy monitorować i ograniczać uruchamianie apletów Java w środowiskach produkcyjnych.

- 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)
Multiple buffer overflows in Sun Java Development Kit (JDK) and Java Runtime Environment (JRE) 5.0 Update 7 and earlier, Java System Development Kit (SDK) and JRE 1.4.2_12 and earlier 1.4.x versions, and SDK and JRE 1.3.1_18 and earlier allow attackers to develop Java applets that read, write, or execute local files, possibly related to (1) integer overflows in the Java_sun_awt_image_ImagingLib_convolveBI, awt_parseRaster, and awt_parseColorModel functions; (2) a stack overflow in the Java_sun_awt_image_ImagingLib_lookupByteRaster function; and (3) improper handling of certain negative values in the Java_sun_font_SunLayoutEngine_nativeLayout function.
