CVE-2026-114431

Enable Media Replace < 4.2.3 - Author+ Stored XSS via SVG Upload

The Enable Media Replace WordPress plugin before 4.2.3 does not pass a replaced media file through the WordPress upload pipeline, so the upload prefilter that SVG-sanitizer Enable Media Replace WordPress plugin before 4.2.3 rely on never runs, allowing an authenticated user with upload access to store an SVG file containing script that executes when the file is opened directly. It requires an SVG-enabling Enable Media Replace WordPress plugin before 4.2.3 to be active, as the replace path otherwise rejects SVG uploads.

CVE-2026-114422

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

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.

CVE-2026-85655

Enable Media Replace <= 4.2.2 - Missing Authorization to Authenticated (Author+) Post Content Modification via Media Replacement Workflow

The Enable Media Replace plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.2.2. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with author-level access and above, to modify the post_content of any published post referencing the replaced media — including Administrator-owned posts — making changes immediately visible to unauthenticated visitors. The doReplaceQuery() method performs a database-wide search-and-replace across all posts containing the old media URL without any per-post capability check, meaning a single Author-triggered request can silently overwrite a large number of posts that WordPress's standard admin UI and REST API would otherwise forbid that user from editing.
