CVE-2026-104812 · Package
NO FIX YET
The Redux Framework plugin for WordPress fails to sanitize array keys in its 'multi_media' field, so a logged-in subscriber can save a crafted key. That key is rendered unescaped into an HTML attribute, letting injected scripts run for any user who opens the affected page.

Sites running the Redux Framework plugin for WordPress that use the multi-media field and allow subscriber-level accounts. Anonymous visitors cannot inject the script, and sites without the plugin are not affected. The sources state that all versions are affected.

The Redux Framework plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'multi_media' Field Array Key in all versions due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The wp_kses_post sanitization applied at save time operates only on array leaf values, leaving array keys entirely unsanitized; the injected key is then rendered directly into an id="filelist-<KEY>" HTML attribute without esc_attr() in Redux_Multi_Media::render(), allowing attribute breakout.
