Subscriber-level stored XSS via unchecked AJAX action
Published Dec 12, 2025 · Updated Dec 12, 2025
Stored XSS in Looks Awesome Flow-Flow Social Streams 3.0.0 through 4.7.5 allows remote authenticated users to execute JavaScript via settings. The flow_flow_social_auth AJAX action accepts Subscriber requests without a capability check, writes attacker-controlled plugin settings, and later renders the stored script on the settings page. Subscriber-level access is sufficient, and execution occurs in the browser of a user who views that administrative page.
