      "summary": "On Tapo\nC520WS v2, restricted accounts (for example, hub users) are intended to execute\nonly a limited set of low‑sensitivity operations. Due to a logic flaw in the\ndevice’s API authorization mechanism, an attacker can craft requests that\nleverage legitimate “method mapping” behavior to bypass whitelist restrictions,\nallowing restricted operations to be masked as permitted requests and executed.\n\n\n\n\n\nSuccessful\nexploitation may allow an attacker (with access to a restricted account) to\nexecute unauthorized sensitive operations. \nDepending on the operation invoked, impact could include device\nresets, unintended configuration changes, or disruption of normal operation,\nleading to loss of availability and integrity of the device.",
