CVE-2025-27378Network attack vector

Unauthenticated SQL injection via inactive parsing configuration

Published Jan 22, 2026 · Updated Jan 22, 2026

SQL injection in Altium On-Prem Enterprise Server 7.0.3 through 7.0.5 allows remote attackers to execute arbitrary SQL queries. An inactive configuration leaves the latest SQL-parsing implementation disabled, so crafted input reaches database query handling without proper neutralization. No authentication or user interaction is required; successful exploitation can read database data, alter records, and interrupt database-backed functions.
