CVE-2024-50491Network attack vector

Unauthenticated SQL injection via unprepared query

Published Oct 28, 2024 · Updated May 11, 2026

SQL injection in Micah Blu's RSVP WordPress plugin 1.9.9 and earlier allows remote attackers to read database data without authentication. A user-supplied request parameter is insufficiently escaped and enters an existing SQL query without adequate preparation. Exposure requires an active plugin on a network-reachable WordPress installation; injected SQL clauses can extract sensitive database information.
