CVE-2026-22225

Administrative device takeover via VPN command injection

Published Feb 2, 2026 · Updated Feb 2, 2026

OS command injection in TP-Link BE230/BE3600 v1.2 before 1.2.4 Build 20251218 rel.70420 allows remote authenticated users to gain device control. The flaw occupies a distinct code path in the VPN Connection Service, but TP-Link has not disclosed the input, command construction, or affected function. Administrative authentication and adjacent-network access are required, after which injected commands grant full control over configuration, network operation, and service availability.
