CVE-2026-5400
Redux Framework <= 4.5.13 - Authenticated (Subscriber+) Cross-Site Scripting via User Input
- Published
- Updated
- Reserved
- Assigned by
- Wordfence
Description
The Redux Framework plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Media field filter values in versions up to, and including, 4.5.13 This is due to insufficient input sanitization of nested array values in the user_meta_save() function and unsafe output of filter CSS values in the render() function without proper 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.
