In plain English
A critical-severity unsafe deserialization in s2Member Pro from WP Sharks. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.9% (higher than 61% of all known vulnerabilities).
Official description
The s2Member Pro plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 241216 via deserialization of untrusted input from the 's2member_pro_remote_op' vulnerable parameter. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
