Top Risky CVEs
| CVE | Summary | Severity | CVSS | EPSS | Priority | Signals |
|---|---|---|---|---|---|---|
| CVE-2025-69762 | Tenda AX3 firmware v16.03.12.11 has a stack overflow in formSetIptv via the list parameter, enabling remote attackers to crash the router or execute arbitrary code. | CRITICAL | 9.8 | 0.4% | 69 |
PoC
No patch
|
| CVE-2025-69763 | Tenda AX3 firmware has a second stack overflow in formSetIptv via the vlanId parameter, allowing remote code execution through the IPTV configuration endpoint. | CRITICAL | 9.8 | 0.4% | 69 |
PoC
No patch
|
| CVE-2025-69766 | Tenda AX3 firmware has a third stack-based buffer overflow in formGetIptv, allowing unauthenticated remote code execution through the router's web interface. | CRITICAL | 9.8 | 0.4% | 69 |
PoC
No patch
|
| CVE-2025-69764 | Tenda AX3 firmware has another stack-based buffer overflow in formGetIptv through a different input path, enabling remote code execution. | CRITICAL | 9.8 | 0.1% | 69 |
PoC
No patch
|
| CVE-2026-4252 | A critical authentication bypass vulnerability exists in Tenda AC8 router firmware version 16.03.50.11 where the IPv6 handler function check_is_ipv6 relies on IP address for authentication, allowing remote attackers to gain unauthorized access. The vulnerability has a publicly available proof-of-concept exploit on GitHub and scores 9.8 CVSS, enabling complete compromise of the affected device with no authentication required. While not currently listed in CISA KEV, the combination of public exploit availability and ease of exploitation makes this a high-priority vulnerability for organizations using affected Tenda routers. | HIGH | 8.9 | 0.1% | 65 |
PoC
No patch
|
| CVE-2026-4567 | Stack-based buffer overflow in Tenda A15 router firmware version 15.13.07.13 allows unauthenticated remote attackers to achieve complete system compromise through a malicious file upload to the UploadCfg function. Public exploit code exists for this vulnerability, and no patch is currently available. The attack requires no user interaction and can be executed over the network with trivial complexity. | HIGH | 8.9 | 0.1% | 65 |
