CVE-2025-14756

Authenticated command execution via crafted admin input

Published Jan 26, 2026 · Updated Feb 26, 2026

Command injection in TP-Link Archer MR600 v5 firmware allows remote authenticated users to execute system commands via the admin interface. The admin interface passes crafted browser-console input to system-command execution without adequate neutralization, but TP-Link does not identify the affected handler or parameter. Administrative authentication and adjacent-network access are required; command length is limited, but execution can interrupt service or fully compromise the router.
