Critical

SQL Injection in Tenable Security Center Ticketing REST API

IdentifiersCVE-2026-64877CWE-89

CVE-2026-64877 is a critical SQL injection vulnerability in the ticketing REST API of Tenable Security Center on Linux. The flaw allows an authenticated non-admin user to inject malicious SQL input through API requests and cause unintended database queries against the appliance backend. Successful exploitation can expose sensitive data stored in the appliance database. Reported affected versions are Security Center releases earlier than 6.8.0, with vendor guidance also indicating affected product coverage across the 6.6.0 through 6.8.0 line prior to application of the dedicated security patch.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows a low-privileged authenticated user to access sensitive information stored in the appliance database. The published CVSS vector indicates high confidentiality and integrity impact with changed scope, suggesting compromise may extend beyond the immediate vulnerable component and permit unauthorized manipulation or retrieval of backend data accessible through the appliance database context. No availability impact has been reported.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, reduce exposure of the ticketing REST API to only trusted administrative networks, minimize the number of accounts with API access, enforce least-privilege role assignments for non-admin users, and monitor for anomalous ticketing API activity and unexpected database access patterns. Because the vulnerability is exploitable by authenticated low-privilege users, restricting account creation and API reachability is the most relevant temporary risk-reduction measure until the patch is applied.

Remediation

Patch, then assume compromise.

Apply Tenable Security Center Patch SC202607.1. Vendor information indicates this patch remediates CVE-2026-64877 and changes affected Security Center versions to unaffected. Where possible, upgrade to a fixed Security Center release and ensure the appliance is running the patched build provided by the vendor.
