Descripción técnica

The LearnPress plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 4.4.10 via deserialization of untrusted input from the 'checkout-email' request parameter during the checkout AJAX action. The value is passed through sanitize_text_field(), which does not strip serialized object syntax, then stored in the LearnPress session table and later fed to LP_Helper::maybe_unserialize() → unserialize() (without an allowed_classes restriction) by LP_Session_Handler::get() on subsequent requests. This makes it possible for unauthenticated attackers to inject a PHP Object.

——0The Duplicator and Duplicator Pro plugins for WordPress are vulnerable to PHP Object Injection in all versions up to, and including, 1.5.17 and 4.6.10, respectively, via deserialization of untrusted database content in DUPX_UpdateEngine::unserializeTest() during migration. This allows unauthenticated attackers to store a serialized object in public site content before an administrator builds a package and later performs a migration or import that runs database search-and-replace. Duplicator Free bundles a Requests 1.7 POP chain that permits attacker-selected callbacks, resulting in direct operating-system command execution. Duplicator Pro bundles an IndexList destructor gadget that permits deletion of an attacker-selected existing file when its containing directory is writable by the installer PHP process; deletion of wp-config.php can expose the setup wizard and lead to site takeover and code execution if the attacker reaches it first and supplies a reachable database they control. The package must be created after the carrier is stored, and a later administrator migration action is required.16h CVE-2026-114198—

——0DokuWiki before 2026-07-14c contains a PHP object injection vulnerability in Draft::getDraftText() that passes draft file contents to unserialize() without restricting allowed classes. Authenticated users with edit rights can race concurrent draft rewrites to splice serialized data, instantiating gadgets like MemoryIndex or Installer for arbitrary file write, deletion, and code execution.23h CVE-2026-1134048.8 ALT
