CVE-2026-5509

Authenticated command execution via unsanitized management input

Published May 27, 2026 · Updated May 27, 2026

Command injection in TP-Link Archer BE450 v1 and BE7200 v1 before 1.3.0 Build 20260416 allows remote authenticated users to execute system commands. The web management backend passes crafted input supplied through the browser developer console to system commands without adequate sanitization. Administrator access to the management interface is required, and successful exploitation runs commands with elevated device privileges, enabling service changes and configuration modification.
