Assigner: Wordfence
Reserved: 02.10.2026 Published: 16.10.2026 Updated: 16.10.2026

The Search Regex plugin for WordPress is vulnerable to PHP Object Injection in version 3.5 via deserialization of untrusted input in the replace_all function. This allows authenticated attackers, with subscriber-level access and above, to inject a PHP Object. The additional presence of a POP chain allows attackers to execute code.
