CVE-2026-114422

Enable Media Replace 4.1.4 - 4.2.2 - Unauthenticated PHP Object Injection via Metadata Replacer

Published Oct 30, 2026 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed
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.
