Technical description
The Event post plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'events_list' shortcodes in all versions up to, and including, 5.9.9 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
