CVE-2025-67987Network attack vector

Subscriber-level database disclosure via is_linking SQL injection

Published Feb 20, 2026 · Updated Feb 20, 2026

SQL injection in ExpressTech Systems Quiz and Survey Master 10.3.1 and earlier allows remote authenticated users to read database data. The question-linking path incorporates the is_linking parameter into a question-ID list used in an SQL query without sufficient escaping or parameter binding. Subscriber-level access is sufficient, and crafted values enable time-based extraction of sensitive database contents without changing stored data.
