CVE-2026-78541

Command execution via stored profile-name metacharacters

Published Aug 24, 2026 · Updated Aug 25, 2026

Stored OS command injection in TP-Link Archer BE3600 V1 before 1.2.6 Build 20260617 allows remote authenticated users to execute commands. The parent-control module accepts shell metacharacters in a profile name and later inserts that stored value into daily cloud report processing without safe neutralization. Exploitation requires administrative access from an adjacent network and grants arbitrary command execution on the router, affecting device and traffic confidentiality, integrity, and availability.
