Summary
The Enable Media Replace plugin for WordPress is affected. An unauthenticated attacker could inject a malicious PHP object that gets run when a user with upload permissions performs a media replacement, potentially allowing local file inclusion of existing PHP or HTML files and, in some conditions, remote code execution on the website's server.

Read the original description
The Enable Media Replace WordPress plugin before 4.2.3 does not restrict the classes allowed when deserializing stored metadata during its media replace-and-update-links routine, allowing unauthenticated users to inject a PHP object that is instantiated when a user with upload access performs a routine media replacement, resulting in PHP Object Injection and local file inclusion of existing PHP/HTML files, which can be escalated to remote code execution where an attacker-influenced PHP or HTML file is present on the server. This is a regression of CVE-2023-4643, which was fixed in 4.1.3 and reintroduced in 4.1.4.
