| CVE-2026-1315 | Hig | 0.49 | 7.5 | 0.01 | Jan 27, 2026 | By sending crafted files to the firmware update endpoint of Tapo C220 v1 and C520WS v2, the device terminates core system services before verifying authentication or firmware integrity. An unauthenticated attacker can trigger a persistent denial of service, requiring a manual… | ||
| CVE-2026-0919 | Hig | 0.49 | 7.5 | 0.01 | Jan 27, 2026 | The HTTP parser of Tapo C210 v3, C220 v1 and C520WS v2 cameras improperly handles requests containing an excessively long URL path. An invalid‑URL error path continues into cleanup code that assumes allocated buffers exist, leading to a crash and service restart. An… | ||
| CVE-2026-0918 | Hig | 0.49 | 7.5 | 0.01 | Jan 27, 2026 | The Tapo C100 v5, C220 v1 and C520WS v2 cameras’ HTTP service does not safely handle POST requests containing an excessively large Content-Length header. The resulting failed memory allocation triggers a NULL pointer dereference, causing the main service process to crash. An… | ||
| CVE-2026-34123 | Hig | 0.46 | — | 0.00 | Jun 6, 2026 | On Tapo C520WS v2, restricted accounts (for example, hub users) are intended to execute only a limited set of low‑sensitivity operations. Due to a logic flaw in the device’s API authorization mechanism, an attacker can craft requests that leverage legitimate “method… | ||
| CVE-2026-6242 | Med | 0.44 | — | 0.00 | Jun 6, 2026 | An authenticated format string vulnerability exists in the ONVIF Subscribe service in Tapo C520WS v2 due to improper handling of externally supplied parameters within formatting functions. An attacker may inject crafted format strings into event subscription requests or… | ||
| CVE-2026-6241 | Med | 0.44 | — | 0.00 | Jun 6, 2026 | An authenticated format string vulnerability is present in the ONVIF AddScopes in Tapo C520WS v2, where user-controlled input is improperly passed to formatting functions without adequate sanitization. An attacker can inject format specifiers into ONVIF scope parameters to… | ||
| CVE-2026-6240 | Med | 0.44 | — | 0.00 | Jun 6, 2026 | A stack-based buffer overflow vulnerability exists in Tapo C520WS v2 in the ONVIF DeleteUsers service, due to insufficient boundary checks when handling multiple user deletion parameters. An authenticated attacker can send a crafted malicious request containing an excessive… | ||
| CVE-2026-6239 | Med | 0.44 | — | 0.00 | Jun 6, 2026 | A stack‑based buffer overflow vulnerability exists in Tapo C520WS v2 in the ONVIF CreateUsers service, where the device fails to properly validate the number of XML user nodes during request processing. An authenticated attacker can send a specially crafted ONVIF request… | ||
| CVE-2025-8065 | Med | 0.42 | 6.5 | 0.01 | Dec 20, 2025 | A stack-based buffer overflow vulnerability was identified in the ONVIF SOAP XML Parser in Tapo C200 v3 and C520WS v2.6. When processing XML tags with namespace prefixes, the parser fails to validate the prefix length before copying it to a fixed-size stack buffer. It allowed a… |
