CVE-2026-120533 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 6.4 (medium) and affects Redux Framework; no fixed version is listed yet.

## Summary

The Redux Framework WordPress plugin, in all versions up to the patched release, has a stored cross-site scripting flaw in its theme_opts parameter on the user profile. An attacker reaches it over the network with a low-privilege account (subscriber level or above) and can inject scripts that run for any user who opens the affected page, but only when the host theme has registered a CSS-emitting Redux field with an output selector.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- davidanderson Redux Framework: through 4.5.16

## Description

The Redux Framework plugin for WordPress is vulnerable to Stored Cross-Site Scripting via theme_opts Parameter via User Profile in all versions up to, and including, 4.5.16 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. Successful exploitation requires the host theme to have registered a Redux field of a CSS-emitting type (such as link_color, border, or typography) with an output CSS selector, as only the field types 'spinner', 'slider', 'color', and 'date' receive per-type value validation that would block the entity-encoded payload.
