CVE-2025-15629: Tp-link omada oc200 v3 firmware vulnerability

Tp Link · Omada Oc200 V3 Firmware

A cryptographic weakness exists in the Omada adoption protocol where session encryption keys used to protect communications between controllers and managed devices may be predictable due to insufficient entropy in session key generation. An attacker who successfully intercepts adoption-related communications may be able to recover session encryption keys and decrypt affected communications.
