CVE-2026-56842 · Severity: high · CVSS 7.5 · Published 2026-07-02

Ubiquiti UniFi Network Application, which is used to manage and configure network devices, contains a security flaw that allows a user to maintain their access even after it should have been revoked. An attacker who already has low-level access to the network could exploit this to keep their administrative or elevated privileges indefinitely. This could lead to unauthorized changes to network settings or long-term monitoring of network traffic.
