# CVE-2026-88999: Redux Framework \<= 4.5.14 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Attachment Deletion via 'attachment\_id' Parameter

- Severity: CVSS 4.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-10-01 · Updated: 2026-10-03

## Affected

- davidanderson Redux Framework: through 4.5.14

## Description

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.
