CVE-2026-114422

Full vulnerability record from the local CVENow database.

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.
