CVE-2026-8714

RTSP service hang via malformed input

Published Jun 5, 2026 · Updated Jun 5, 2026

Denial of service in the RTSP server of TP-Link Tapo C520WS V2 allows remote attackers to hang the service via malformed input. The RTSP input-handling logic mishandles syntactically invalid requests and enters a processing-error state that leaves the service non-responsive. Attackers need access to the same network segment and no credentials or user interaction; the documented consequence is loss of RTSP streaming.
