CVE-2025-52737Network attack vector

Authenticated PHP object injection via untrusted deserialization

Published Oct 22, 2025 · Updated Oct 22, 2025

PHP object injection in WP Store Locator 2.2.260 and earlier allows remote authenticated users to inject objects via serialized input. Published advisories do not identify the affected function, parameter, or code path that deserializes the attacker-controlled value. Contributor-level access is required; no known POP chain exists in the plugin, so file deletion, data disclosure, or code execution also requires a gadget chain from another plugin or theme.
