CVE-2026-34124 Apr 02, 17:20 HIGH PATCH This Week

Denial-of-service vulnerability in TP-Link Tapo C520WS v2.6 camera allows adjacent network attackers to trigger buffer overflow through crafted HTTP requests with excessively long paths that bypass initial length validation during path normalization, resulting in memory corruption and device reboot without requiring authentication. Vendor has released a patch; no public exploit code identified at time of analysis.

CVE-2026-34121 Apr 02, 17:20 HIGH PATCH This Week

TP-Link Tapo C520WS v2.6 contains an authentication bypass in its HTTP-based DS configuration service that allows unauthenticated attackers to execute privileged device configuration actions by appending authentication-exempt parameters to requests. The vulnerability stems from inconsistent JSON request parsing and authorization logic, enabling unauthorized modification of device state without requiring valid credentials. No public exploit code has been identified at time of analysis, and a vendor-released patch is available.

CVE-2026-34120 Apr 02, 17:19 HIGH PATCH This Week

Heap-based buffer overflow in TP-Link Tapo C520WS v2.6 allows local network attackers to cause denial of service by sending crafted payloads during asynchronous video stream processing, triggering memory corruption and process crashes. The vulnerability stems from insufficient buffer boundary validation in streaming input handling. A vendor patch is available.

CVE-2026-34119 Apr 02, 17:19 HIGH PATCH This Week

Heap-based buffer overflow in TP-Link Tapo C520WS v2.6 allows unauthenticated network attackers to trigger denial-of-service by sending crafted HTTP payloads that bypass boundary validation during segmented request body parsing. The vulnerability exploits insufficient write-boundary verification in the HTTP parsing loop, causing heap memory corruption that crashes or hangs the device process. Patch is available from the vendor.

CVE-2026-34118 Apr 02, 17:19 HIGH PATCH This Week

Heap-based buffer overflow in TP-Link Tapo C520WS v2.6 allows remote attackers on the same network segment to trigger denial-of-service by sending crafted HTTP POST payloads that exceed allocated buffer boundaries. The vulnerability stems from missing validation in HTTP body parsing logic, causing process crashes or unresponsiveness. No CVSS score or vector data is available, limiting precise severity quantification, but the practical attack vector is network-adjacent and does not require authentication.
