Summary
The Events Made Easy plugin for WordPress is affected in all versions up to and including 3.2.22. Insufficient input sanitization and output escaping (CWE-79) let an unauthenticated attacker store arbitrary web scripts through the event location name parameter. The scripts run whenever a user opens an affected page, but only if a site administrator enables both guest event submission and forced location creation, which both default to off.

Description from the CNA
The Events Made Easy plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'event[location_name]' parameter in all versions up to, and including, 3.2.22 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This vulnerability is only exploitable when both the guest event submission feature (eme_fs[guest_submit]) and forced location creation (eme_fs[force_location_creation]) are explicitly enabled by a site administrator, as both settings default to off.
