CVE-2025-7504Network attack vector

Authenticated object injection via query_vars deserialization

Published Jul 12, 2025 · Updated Jul 14, 2025

PHP object injection in Alex Kirk Friends 3.5.1 allows remote authenticated users to inject objects through a crafted query_vars value. The plugin passes attacker-controlled query_vars data to PHP deserialization, permitting instantiated classes to invoke an available POP chain. Exploitation requires subscriber-level access, the site's SALT_NONCE and SALT_KEY, and a POP chain from another plugin or theme; effects can include file deletion, data disclosure, or code execution.
