CVE-2026-3279
No known patch is available for this vulnerability.
The affected plugin has been removed from the WordPress.org directory, and no patched version is being distributed through the official directory. If you have the affected software installed, you should uninstall or replace it rather than wait for an update.
Description
The Enable jQuery Migrate Helper plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the downgrade_jquery_version() function in all versions up to, and including, 1.4.1. This is due to the function only verifying a nonce without checking user capabilities. This makes it possible for authenticated attackers, with Subscriber-level access and above, to downgrade the site-wide jQuery version from 3.7.1 to the legacy 1.12.4-wp release, which has knowns security vulnerabilities.
