CVE-2026-15314

Web service crash via unchecked request-body copy

Published Aug 4, 2026 · Updated Aug 4, 2026

Buffer overflow in the TP-Link Tapo P110 v1 web service before V1_1.1.4 Build 260709 allows remote attackers to crash or restart it. The authenticated HTTP request-body handler copies attacker-controlled data into memory without validating its size against the destination buffer. An attacker must reach the plug from an adjacent network; successful exploitation interrupts the web service but has no reported confidentiality or integrity impact.
