CVE-2023-41652Public exploitNetwork attack vector

Database disclosure via unprepared email query

Published Nov 3, 2023 · Updated Apr 29, 2026

SQL injection in David F. Carr RSVPMaker 10.6.6 and earlier allows remote attackers to read WordPress database data via the email parameter. The rsvpmailer_member REST route passes the user-supplied email value into an existing SQL query without sufficient escaping or parameter preparation. Unauthenticated access to the route is sufficient; crafted SQL can extract sensitive database information through time-based blind queries.
