CVE-2022-1768Public exploitNetwork attack vector

Unauthenticated database disclosure via unquoted RSVP identifier

Published Jun 13, 2022 · Updated Apr 8, 2026

SQL injection in David F. Carr RSVPMaker 9.3.2 and earlier allows remote attackers to read database data through a crafted REST request. The rsvp_confirmation_after_payment function interpolates the POST rsvp_id value without quotes or a prepared query in two SQL statements. No authentication or user interaction is required, and a nonempty email value routes the identifier to the vulnerable function.
