DescriptionTP-Link Tapo C325WB V2 contains an unauthenticated authorization bypass vulnerability in the HTTPS JSON API dispatcher on TCP port 443. An attacker on the adjacent network can append an onboarding-scoped object to a JSON request to bypass session verification and invoke privileged actions without authentication.  Successful exploitation may allow an unauthenticated adjacent-network attacker to access live video and audio, modify device settings, and obtain sensitive device information or secrets.
