Summary
The Event Organiser plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to and including 3.12.9. This is due to the 'eo_events' shortcode accepting attacker-controlled 'no_events' content and rendering it in event list templates without output escaping.
Risk Assessment
Authenticated attackers with Contributor-level access or above can inject arbitrary web scripts in pages that execute whenever a user accesses an injected page, potentially leading to session theft, redirects, or other malicious actions.
Recommendation
Immediately update the Event Organiser plugin to the latest available version that fixes this vulnerability, and restrict user permissions to the minimum necessary.
Original NVD description (English source)
The Event Organiser plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 3.12.9. This is due to the 'eo_events' shortcode accepting attacker-controlled 'no_events' content and rendering it in event list templates without output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
