CVE-2026-9254

Root command execution via parental-control parameters

Published Aug 24, 2026 · Updated Aug 25, 2026

OS command injection in TP-Link Archer BE800 V1, BE3600 V1, and AX75 V1 allows remote attackers on the LAN to execute root commands. The parental control functionality fails to filter and neutralize shell metacharacters in certain parameters before OS command execution; parameter names remain undisclosed. No authentication is required, but the attacker must reach the router from its LAN; exploitation permits complete device and network-traffic compromise.
