Redux Framework - Security Vulnerability (CVE-2026-88999)

CVE-2026-88999

Vulnerability CVE-2026-88999 PLUGIN redux-framework MEDIUM

The Redux Framework plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.5.14 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 subscriber-level access and above, to delete arbitrary media library attachments, including administrator-owned files, from the affected site. This is exploitable by Subscribers when a Custom Fonts field is registered on the user profile page via Redux_Users::set_profile(), as doing so causes the required redux_custom_fonts nonce to be rendered into the Subscriber's wp-admin/profile.php page.

What to do about this

Patch on your next cycle Worth fixing, but not ahead of other work.

Fix it

Update Redux Framework to the latest available version.

Where the vendor has not published a fix yet, disable the plugin until they do.

Cannot update today? Request / payload inspection (WAF) in Hack Halt ProSecure blocks this class of attack before WordPress processes the request.

Inspect request parameters and bodies for injection, traversal and file-inclusion payloads, and refuse the request rather than logging it.

Am I affected by this vulnerability?

You are affected if your site runs Redux Framework.

How do I fix it?

Update Redux Framework to the latest available version. Where the vendor has not yet published a fix, remove or disable the plugin until they do. Until you can update, Request / payload inspection (WAF) in Hack Halt ProSecure contains this class of attack at the request layer.

What can an attacker actually do?

This is a Broken Access Control flaw. An attacker who exploits it can reach actions or data that should have been restricted to someone else.
