CVE-2026-64877Network attack vector

Authenticated database access via ticketing API SQL injection

Published Jul 21, 2026 · Updated Jul 21, 2026

SQL injection in Tenable Security Center 6.6.0 through 6.8.0 allows remote authenticated users to access sensitive appliance data. The ticketing REST API passes attacker-controlled request data into a database query without sufficient input validation; Tenable has not disclosed the affected endpoint or query construction. A non-admin account is required, and the documented consequence is database data access rather than service interruption.
