CVE-2026-90992 · Severity: medium · CVSS 6.4 · Published 2026-10-01

The Redux Framework plugin for WordPress allows authenticated users with Subscriber-level access to inject malicious scripts into pages by exploiting user meta fields during a media URL repair. When an affected page is visited, these scripts execute automatically, potentially compromising user accounts, stealing sensitive data, or performing unauthorized actions on the site.

## Technical details

The plugin fails to properly sanitize and escape user-supplied data in the 'user-mediaurl' media field and related user meta fields (biography, session_tokens, persisted_preferences). Authenticated attackers can store malicious payloads in these fields, which are then promoted to the site-wide redux_demo option during media URL repair, resulting in stored XSS that executes in the browsers of all users accessing the affected pages.
