Technical details

A Missing Authorization vulnerability (CWE-862) exists in the ThimPress Thim Core plugin for WordPress through version 2.3.3. The flaw allows an authenticated attacker, typically with Subscriber-level privileges, to bypass access controls due to insufficient validation of user permissions within certain plugin functions. According to the advisory, this lack of authorization can be leveraged to achieve arbitrary code execution (ACE). The attack is reachable over the network and does not require user interaction. As of the disclosure, no official patch has been released by the vendor.
