Impact
Authenticated attackers on the adjacent network can execute arbitrary commands with root privileges and take full control of the camera. They need local network access and valid high-privilege credentials to exploit the flaw.
Root cause
A stack-based buffer overflow occurs when handling an oversized encrypted password field in the local onboarding Wi-Fi configuration path.
Affected systems
Tapo C320WS V2.0 (exact firmware versions not listed — check vendor advisory)

Fix & remediation
Upgrade to the latest firmware release for Tapo C320WS V2.0 via the TP-Link support portal or Tapo app. As an interim mitigation, isolate the camera on a dedicated IoT VLAN with restricted adjacent network access and change administrative credentials.
AI-suggested. Run it in staging first and check it against the vendor advisory. Why?
NVD description
Tapo C320WS V2.0 contains an authenticated stack-based buffer overflow in the local onboarding Wi-Fi configuration path. An authenticated attacker on the adjacent network can submit a crafted request containing an oversized encrypted password field, overwrite stack state, and execute commands with root privileges. Successful exploitation may allow an authenticated adjacent-network attacker to take control of the affected camera, modify camera behavior, access sensitive local configuration, and disrupt device availability.
