CVE-2026-1800Network attack vector

Unauthenticated database disclosure via unprepared SQL query

Published Mar 21, 2026 · Updated Mar 21, 2026

Time-based SQL injection in Fonts Manager | Custom Fonts 1.2 and earlier allows remote attackers to read database data via crafted requests. The plugin passes the unauthenticated fmcfIdSelectedFnt request parameter into an existing SQL query without sufficient escaping or prepared-query binding. Any network client that can reach the affected WordPress endpoint can use time delays to infer sensitive database values without an account or user interaction.
