CVE-2026-16586Network attack vector

Database disclosure via second-order cgRealId SQL injection

Published Aug 15, 2026 · Updated Aug 15, 2026

Second-order SQL injection in Contest Gallery 30.0.7 and earlier allows remote authenticated users to read database data via cgRealId. The MultipleFiles cg_multiple_files_for_post flow stores an unescaped cgRealId value and later inserts it into an inadequately prepared SQL query. Author-level WordPress access or higher is required; successful injection appends SQL to existing queries and exposes sensitive database information.
