Technical Analysis

CVE-2026-86091 is a missing authorization vulnerability in ntopng prior to version 6.7.260717. The flaw exists in the pools bulk-delete endpoint, which fails to verify user privileges properly. As a result, authenticated non-administrative users can issue POST requests to delete all host pools and their member bindings. This leads to the destruction of traffic policy bindings and visibility restrictions, undermining security policies enforced by the application.

Potential Impact

An attacker with valid authentication but without administrative rights can delete all host pools and associated member bindings. This irreversible deletion removes traffic policy bindings and visibility restrictions, potentially allowing unauthorized traffic flows and bypassing security policies that rely on these controls. The vulnerability has a CVSS 4.0 score of 7.1, indicating high severity.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the pools bulk-delete endpoint to trusted administrators only and monitor for unauthorized use of this functionality.
