AnalysisAI
Stored cross-site scripting in WP-FB-AutoConnect plugin for WordPress allows authenticated administrators to inject malicious scripts via improperly neutralized input. Affects versions up to 4.6.3. No public exploit or active exploitation identified; EPSS score is low (0.04%).
Technical ContextAI

The plugin fails to sanitize user-supplied input before storing it, allowing stored scripts to execute in the context of other users' browsers. The CVSS vector indicates high privileges required (PR:H) and user interaction (UI:R), meaning an administrator must be tricked into performing an action.
RemediationAI
Update WP-FB-AutoConnect to version 4.6.4 or later if available. As no patch version is confirmed, consider disabling the plugin until a fix is released. Alternatively, apply input sanitization and output encoding via a Web Application Firewall (WAF) to mitigate XSS attacks. Note that disabling the plugin may break Facebook login functionality.
