Description

The Event RSVP and Simple Event Management Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'emd_mb_meta' shortcode in all versions up to, and including, 4.1.0 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.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • emarket-design Event RSVP and Simple Event Management Plugin — Up to and including 4.1.0
  • emarketdesign event_rsvp_and_simple_event_management — Up to and including 4.1.0
