CVE-2025-56385Network attack vector

Authentication bypass via unsanitized login query

Published Nov 12, 2025 · Updated Nov 12, 2025

SQL injection in WellSky Harmony 4.1.0.2.83 allows remote attackers to bypass authentication and access backend data via the login interface. The xmHarmony.asp endpoint inserts the TXTUSERID parameter directly into a backend SQL query without sanitization or parameterization. The login page is reachable before authentication; database reading, modification, or deletion depends on the application database account's privileges.
