Recommendation: Monitor — no exploitation signal at the moment.
The Tapo C100 v5, C220 v1 and C520WS v2 cameras’ HTTP service does not safely handle POST requests containing an excessively large Content-Length header. The resulting failed memory allocation triggers a NULL pointer dereference, causing the main service process to crash. An unauthenticated attacker can repeatedly crash the service, causing temporary denial of service. The device restarts automatically, and repeated requests can keep it unavailable.
