CVE-2024-12562Network attack vector

Unauthenticated PHP object injection via remote API

Published Feb 15, 2025 · Updated Apr 8, 2026

PHP object injection in WP Sharks s2Member Pro 241216 and earlier allows remote attackers to inject objects through its Remote Operations API. The API handler deserializes untrusted data supplied in the s2member_pro_remote_op request parameter instead of accepting only the documented JSON form. No authentication is required; harmful effects require a compatible POP chain from another installed plugin or theme and include file deletion, data access, or code execution.
