CVE-2026-73366Network attack vector

Arbitrary object instantiation via unsafe deserialization

Published Aug 18, 2026 · Updated Aug 18, 2026

PHP object injection in Easy Google Maps before 1.14.0 allows remote attackers to instantiate arbitrary PHP objects via crafted serialized input. Patchstack and NVD identify deserialization of attacker-controlled data, but retrieved public records do not name the exact function, parameter, or request path in the vulnerable code. No authentication or user interaction is required; follow-on impact depends on a usable POP chain in the site's WordPress and PHP runtime, and can extend to code execution or destructive actions.
