CVE-2016-15033
CriticalSummary
Wtyczka Delete All Comments dla WordPressa jest podatna na nieautoryzowane przesyłanie plików z powodu braku walidacji typu pliku w pliku delete-all-comments.php w wersjach do 2.0 włącznie. Umożliwia to nieautoryzowanym atakującym przesyłanie dowolnych plików na serwerze dotkniętej witryny.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do przesyłania złośliwych plików, co może prowadzić do zdalnego wykonania kodu na serwerze, stwarzając poważne zagrożenie dla bezpieczeństwa organizacji.
Recommendation
Zaleca się aktualizację wtyczki do najnowszej wersji oraz wdrożenie dodatkowych mechanizmów zabezpieczających, takich jak walidacja typów plików i ograniczenia dostępu do krytycznych plików na serwerze.

Postiz signs its session, invitation and password reset tokens with one shared secret and without any marker of what a token is for. A route that refreshes the credentials of a browser-extension channel signed data taken from the request itself and stored the result where the requesting user can read it back, allowing a user to obtain a validly signed token containing any claims they choose, accepted as a session, an organization invitation with a chosen role, a password reset or an enterprise provisioning token.

Python has added a denylist for known compromised certificates to the "ssl" module to ensure user safety even without certificate revocation configured. Known compromised certificates will automatically be rejected regardless of the SSLContext policy configuration.
- CVE-2026-115932Critical
In Postiz, a media path that is not a web address is treated as a file on the server's disk without verifying it lies inside the upload directory. A registered user can store a crafted media path with a post and cause the publishing worker to read an arbitrary file and send it as an attachment to a Discord server the user controls. The same unconfined reads are reachable through two further routes, including file existence checks and backend memory exhaustion; self-registration is open by default.

- CVE-2026-115806Critical
The Prime Mover – Backup and Migration plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.2.1 via deserialization of untrusted input in the migration search-and-replace routine. An unauthenticated attacker can store a crafted, base64-encoded serialized object in wp_comments.comment_content through the standard comment-submission endpoint. When an administrator performs a routine export or restore, the plugin base64-decodes that stored value and passes it to unserialize() with no allowed_classes restriction. A Property-Oriented Programming (POP) chain is present in the plugin's own bundled Freemius library, so no additional plugin or theme is required.
