CVE-2026-5509
7.2 · HIGHOverview
CVE-2026-5509 is a high-severity vulnerability affecting tp-link archer_be450_firmware. It was published on May 27, 2026 and has a CVSS 3.1 base score of 7.2 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.2, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
An authenticated command injection vulnerability exists in the Archer BE450 v1 and BE7200 v1 router that allows an administrator to execute arbitrary system commands through the web management interface. After successfully authenticating to the admin interface, an attacker can leverage the browser’s developer console by supplying a crafted input that is passed to backend system commands without adequate sanitization.
Successful exploitation enables execution of arbitrary commands with elevated privileges on the device, which may allow the attacker to start unauthorized services, modify system configuration, or otherwise fully compromise the router’s operating environment.
Remediation
Check the references section for vendor advisories and patches from tp-link. Update archer_be450_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
