CVE-2026-85655 Details
Description
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.
A vulnerability exists in the Enable Media Replace plugin for WordPress, affecting all versions through 4.2.2. The issue stems from improper authorization checks, allowing authenticated users with author-level access and above to bypass restrictions and modify the post content of any published post that references the replaced media. This includes posts owned by administrators. The vulnerability arises because the doReplaceQuery() method conducts a database-wide search-and-replace for old media URLs without checking per-post capabilities. As a result, a single request from an author can silently overwrite multiple posts, including those that the user would typically be barred from editing via WordPress's standard admin interface or REST API.
Users are advised to update the Enable Media Replace plugin to version 4.2.3 or a newer patched version.
