CVE-2026-6239: CWE-121 Stack-based buffer overflow in TP-Link Systems Inc. Tapo C520WS v2CVE-2026-6239 0 CVE-2026-6239 is a stack-based buffer overflow vulnerability in the ONVIF CreateUsers service of TP-Link Tapo C520WS v2 devices. The vulnerability arises because the device does not properly validate the number of XML user nodes in requests. An authenticated attacker can exploit this by sending a specially crafted ONVIF request with excessive user entries, causing memory corruption. Successful exploitation results in the ONVIF management service terminating unexpectedly, leading to a denial-of-service (DoS) condition that disrupts device configuration and management. The vulnerability has a CVSS 4. 0 base score of 6. 8, indicating medium severity. There is no information on available patches or official remediation at this time.
