CVE-2026-104945 · Severity: info · Published 2026-10-06

The TP-Link Tapo C500 is an outdoor pan-tilt security camera that supports ONVIF protocol for remote management and PTZ (pan, tilt, zoom) control. An authenticated attacker can send a specially crafted SOAP request to the ONVIF service that crashes the camera's management functionality, causing a denial-of-service condition that disrupts camera control and monitoring until the service recovers.

## Technical details

An out-of-bounds stack write vulnerability exists in the ONVIF PTZ SOAP handlers due to insufficient bounds checking on preset-related array elements. An authenticated ONVIF client can submit an excessive number of preset elements, causing writes beyond fixed-size stack arrays. This results in service crash but does not appear to enable code execution.
