| 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 |
PoC
No patch
|
| CVE-2026-4489 | Stack-based buffer overflow in Tenda A18 Pro firmware version 02.03.02.28 allows authenticated remote attackers to achieve complete system compromise through the /goform/fast_setting_wifi_set endpoint. Public exploit code is available and actively being weaponized against this unpatched vulnerability.

An authenticated attacker can execute arbitrary code remotely without user interaction, affecting confidentiality, integrity, and availability of affected devices. | HIGH | 8.8 | 0.0% | 64 |
PoC
No patch
|
| CVE-2026-4492 | Remote code execution in Tenda A18 Pro firmware 02.03.02.28 allows authenticated attackers to achieve full system compromise through stack-based buffer overflow in the QoS configuration function. Public exploit code exists for this vulnerability and no patch is currently available, leaving deployed devices at immediate risk. | HIGH | 8.8 | 0.0% | 64 |
PoC
No patch
|
| CVE-2026-4493 | Stack-based buffer overflow in Tenda A18 Pro MAC filtering configuration allows remote authenticated attackers to achieve full system compromise through manipulation of the deviceList parameter. Public exploit code exists for this vulnerability, and no patch is currently available. The flaw impacts the /goform/setMacFilterCfg endpoint with a CVSS score of 8.8. | HIGH | 8.8 | 0.0% | 64 |
PoC
No patch
|
| CVE-2026-5684 | Stack-based buffer overflow in Tenda CX12L router firmware version 16.03.53.12 enables adjacent network attackers with low-level credentials to execute arbitrary code or crash the device. The vulnerability resides in the webExcptypemanFilter function's handling of the 'page' parameter. Publicly available exploit code exists (GitHub POC published), elevating immediate risk for exposed devices. CVSS 8.6 reflects high impact across confidentiality, integrity, and availability within the adjacent network attack surface. | HIGH | 8.6 | 0.0% | 63 |
