Descripción técnica

The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 6.3.2 via deserialization of untrusted input . This makes it possible for authenticated attackers, with administrator-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present. By default, Editor-level users are granted FULL_ACCESS to the plugin's import endpoint via the KIRKI_USERS_DEFAULT_FULL_ACCESS configuration, meaning exploitation is possible at Editor privilege level rather than being restricted to administrators alone.

——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
