Name of the Vulnerable Software and Affected Versions Event Organiser versions prior to 3.13.0

Description The Event Organiser plugin for WordPress contains a Stored Cross-Site Scripting issue. This occurs because the eo events shortcode accepts attacker-controlled no events content and renders it in event list templates without proper output escaping. Authenticated attackers with Contributor-level access or higher can inject arbitrary web scripts into pages, which then execute when a user visits the affected page.

Recommendations Update the plugin to a version later than 3.12.9.
