Top Risky CVEs
| CVE | Summary | Severity | CVSS | EPSS | Priority | Signals |
|---|---|---|---|---|---|---|
| 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-2025-69765 | Tenda AX3 firmware v16.03.12.11 contains a stack overflow in formGetIptv function and the list parameter, which can cause memory corruption and enable remote code execution. [CVSS 7.5 HIGH] | HIGH | 7.5 | 0.3% | 58 |
PoC
No patch
|
| CVE-2025-70252 | An issue was discovered in /goform/WifiWpsStart in Tenda AC6V2.0 V15.03.06.23_multi. The index and mode are controllable. [CVSS 7.5 HIGH] | HIGH | 7.5 | 0.1% | 58 |
PoC
No patch
|
| CVE-2026-7096 | OS command injection in Tenda HG3 router version 2.0 (build 300003070) allows authenticated remote attackers to execute arbitrary system commands with router privileges via the fmgpon_loid parameter in the formgponConf administrative function. Public exploit code is available and confirmed usable for attacks per VulDB reporting, significantly lowering the skill barrier for exploitation despite requiring valid administrative credentials. | HIGH | 7.4 | 0.3% | 57 |
PoC
No patch
|
| CVE-2026-7160 | A vulnerability was determined in Tenda HG3 2.0. This vulnerability affects the function formTracert of the file /boaform/formTracert. Executing a man | HIGH | 7.4 | 0.3% | 57 |
PoC
No patch
|
| CVE-2026-4565 | Buffer overflow in Tenda AC21 firmware version 16.03.08.16 allows authenticated remote attackers to achieve complete system compromise through crafted QoS configuration requests to the SetNetControlList endpoint. Public exploit code exists for this vulnerability, and no patch is currently available. An attacker with valid credentials can execute arbitrary code with full system privileges (confidentiality, integrity, and availability impact). | HIGH | 7.4 | 0.1% | 57 |
PoC
|
| CVE-2026-6123 | Stack-based buffer overflow in Tenda F451 router firmware 1.0.0.7 enables authenticated remote attackers to execute arbitrary code with high privileges via crafted 'entrys' parameter to the /goform/addressNat endpoint. The vulnerability resides in the fromAddressNat function of the httpd component. Public exploit code is available (GitHub), with EPSS indicating moderate exploitation probability. Requires low-privilege authentication (PR:L) but has low attack complexity (AC:L), making it accessible to attackers with basic router credentials. | HIGH | 7.4 | 0.1% | 57 |
PoC
No patch
|
| CVE-2026-7056 | Buffer overflow in Tenda F456 router firmware 1.0.0.5 allows authenticated remote attackers to achieve arbitrary code execution with high impact to confidentiality, integrity, and availability. The vulnerability resides in the SafeUrlFilter functionality of the httpd web server component, triggered by manipulating the 'page' parameter. A public proof-of-concept exploit is available on GitHub, significantly lowering the barrier to exploitation, though no CISA KEV listing or widespread exploitation has been confirmed at time of analysis. | HIGH | 7.4 | 0.1% | 57 |
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. Attackers with network access and valid credentials can execute arbitrary code with full system privileges. | HIGH | 7.4 | 0.0% | 57 |
PoC
No patch
|
| CVE-2026-4490 | Stack-based buffer overflow in Tenda A18 Pro firmware version 02.03.02.28 enables authenticated remote attackers to achieve code execution with high privileges through the setSchedWifi function. Public exploit code is available for this vulnerability, and no patch has been released, leaving affected devices exposed to active exploitation. An attacker with network access and valid credentials can trigger the overflow to compromise system integrity and confidentiality. | HIGH | 7.4 | 0.0% | 57 |
PoC
No patch
|
| CVE-2026-4491 | Stack-based buffer overflow in Tenda A18 Pro firmware version 02.03.02.28 allows remote attackers with low privileges to achieve complete system compromise through manipulation of the SetIpMacBind function arguments. Public exploit code exists for this vulnerability, and no patch is currently available. An authenticated attacker can execute arbitrary code remotely without user interaction, affecting confidentiality, integrity, and availability of affected devices. | HIGH | 7.4 | 0.0% | 57 |
PoC
