CVE-2024-10936Network attack vector

Unauthenticated PHP object injection via replacement deserialization

Published Jan 21, 2025 · Updated Apr 8, 2026

PHP object injection in InstaWP String Locator 2.6.6 and earlier allows remote attackers to inject objects via crafted replacement data. The recursive_unserialize_replace function deserializes untrusted replacement data, allowing PHP objects to be instantiated. Exploitation requires an administrator to run search and replace and a gadget chain from another plugin or theme; without that chain, injection has no reported file deletion, data access, or code execution consequence.
