Two high-severity vulnerabilities have been disclosed in Tenda router firmware, both affecting the SafeMacFilter functionality and both reported as remotely exploitable with public proof-of-concept code available. CVE-2026-7031 impacts Tenda F456 firmware 1.0.0.5, where the fromSafeMacFilter function in /goform/SafeMacFilter can be triggered into a buffer overflow by manipulating the page argument. The flaw was mapped to CWE-119 and CWE-120, with CVSS records indicating high impact on confidentiality, integrity, and availability.
A second issue, CVE-2026-7470, affects Tenda 4G300 firmware US_4G300V1.0Mt_V1.01.42_CN_TDC01 and involves a stack-based buffer overflow in the sub_427C3C function of the same /goform/SafeMacFilter component, again via the page parameter. The vulnerability was mapped to CWE-119 and CWE-121, and references for both disclosures point to VulDB entries, GitHub exploit material, and Tenda resources, indicating that multiple Tenda devices share a similar attack surface in SafeMacFilter request handling.

Two high-severity vulnerabilities have been disclosed in Tenda routers, both enabling remote stack-based buffer overflows through exposed `/goform/` endpoints. **CVE-2026-4551** affects the Tenda **F453** running version `1.0.0.3`, where the `fromSafeClientFilter` function in the `/goform/SafeClientFilter` handler can be exploited by manipulating the `menufacturer/Go` argument. **CVE-2026-5990** affects the Tenda **F451** running version `1.0.0.7`, where the `fromSafeEmailFilter` function in the `/goform/SafeEmailFilter` component can be triggered via the `page` argument. Both flaws are classified under **CWE-119** and **CWE-121** and are described as remotely exploitable with **public exploit information available**, raising the risk of active abuse against exposed devices. The CVE records assign high impact across **confidentiality, integrity, and availability** in published CVSS scoring, indicating that successful exploitation could give attackers a powerful path to compromise vulnerable edge networking equipment.

Several high-severity vulnerabilities have been disclosed in the **Tenda F456** router running firmware `1.0.0.5`, affecting the device’s `httpd` component across multiple `/goform/` endpoints. The flaws include `CVE-2026-7053` in `frmL7ProtForm` via `/goform/L7Prot`, `CVE-2026-7055` in `fromVirtualSer` via `/goform/VirtualSer`, `CVE-2026-7056` in `fromSafeUrlFilter` via `/goform/SafeUrlFilter`, and `CVE-2026-7057` in `/goform/setcfm`. In each case, crafted input to parameters such as `page`, `menufacturer`, `Go`, `funcname`, or `funcpara1` can trigger a buffer overflow. The vulnerabilities are described as **remotely exploitable** and have been mapped to `CWE-119` and `CWE-120`, with CVSS scoring indicating high impact to confidentiality, integrity, and availability. Public exploit code has also been reported for all four issues, including references to VulDB and GitHub proof-of-concept material, raising the risk of active attacks against exposed devices. Organizations using affected Tenda F456 routers should treat the flaws as urgent exposure in internet-facing network infrastructure.

Two high-severity vulnerabilities have been disclosed in Tenda router firmware, affecting **FH451 1.0.0.9** and **F453 1.0.0.3**. The flaws are tracked as `CVE-2026-4534` and `CVE-2026-4552` and both involve remotely reachable stack-based buffer overflows in web management handlers. In the FH451 case, the issue is in the `formWrlExtraSet` function exposed through the `/goform/WrlExtraSet` component, where manipulation of the `GO` argument can trigger memory corruption. In the F453 case, the vulnerable code is the `fromVirtualSer` function behind the `/goform/VirtualSer` endpoint, where the `page` argument can be abused to cause a similar overflow. Both CVE records indicate that **public exploits are available**, increasing the likelihood of opportunistic attacks against exposed devices. The disclosures map the weaknesses to `CWE-119` and `CWE-121`, reflecting out-of-bounds memory handling and stack-based buffer overflow conditions, and the published scoring points to high impact on confidentiality, integrity, and availability. Organizations using these Tenda models should treat the flaws as urgent remote compromise risks, especially where router administration interfaces are internet-accessible.
