Events Made Easy <= 3.2.22 - Unauthenticated Stored Cross-Site Scripting via 'event[location_name]' Parameter
What fixes it
No source in this snapshot names a fixed version. The vendor advisories under References are the place to check.
Description
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.
