CVE-2022-2440

What is CVE-2022-2440?

The Theme Editor plugin for WordPress is susceptible to a deserialization vulnerability that affects versions up to and including 2.8. The vulnerability arises from improper handling of the 'images_array' parameter, which allows authenticated users with administrative privileges to perform unauthorized actions. By utilizing a PHAR wrapper, attackers can potentially deserialize arbitrary PHP objects that may lead to further exploits, assuming they can successfully upload a file containing a serialized payload. This vulnerability underscores the importance of keeping WordPress plugins updated to mitigate security risks.
