CVE-2026-104945

Authenticated ONVIF PTZ Out-of-Bounds Stack Write Denial of Service in TP-Link Tapo C500

Published Oct 6, 2026 CVSS 4.0 · 6.8 Medium EPSS < 1% KEV · Not listed
Description
TP-Link Tapo
C500 v2.0 contains an out-of-bounds stack write vulnerability in its ONVIF PTZ
SOAP handlers. An authenticated ONVIF client can submit an excessive number of
preset-related elements, causing writes beyond the bounds of fixed-size stack
arrays and resulting in a crash of the affected service.









Successful
exploitation may allow an authenticated attacker to cause the affected service
to crash, resulting in a denial-of-service condition. Repeated exploitation may
repeatedly disrupt camera management and PTZ-related functionality until the
service recovers or restarts.
