CVE-2026-9032NVD
Vulnerability Summary
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.
