Original source text (not a translation)
An authentication bypass vulnerability within the HTTP handling of the DS configuration service in TP-Link Tapo C520WS v2.6 and C210 v3 was identified, due to inconsistent parsing and authorization logic in JSON requests during authentication check. An unauthenticated attacker can append an authentication-exempt action to a request containing privileged DS do actions, bypassing authorization checks.
Successful exploitation allows unauthenticated execution of restricted configuration actions, which may result in unauthorized modification of device state.
