What is CVE-2026-9032?
CVE-2026-9032 is a high-severity vulnerability in TP-Link Systems Inc. Tapo C120 V1, published on 1 Oct 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
Tapo C120 v1 and C200 v5 contain a NULL pointer dereference in the HTTPS onboarding connect request parser. The interface is reachable without authentication after initial setup and does not validate that a password field is present for certain authentication and encryption parameter combinations, allowing a malformed request from the same local network to crash the HTTPS service
Successful exploitation may temporarily make HTTPS management functions unavailable. Repeated malformed requests may sustain the denial-of-service condition, and recovery may in some cases require a device reboot.
Weakness: CWE-476
