    CVE-2026-82814 (GCVE-0-2026-82814)

    Title
    Duplicator <= 1.5.17 and Duplicator Pro <= 4.6.10 - Unauthenticated PHP Object Injection
    Summary
    The 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.
