CVE-2026-19981

A weakness has been identified in GL.iNet A1300, AX1800, AXT1800, BE1400, BE3600, BE6500, BE9300, BE10000, E5800, MT2500, MT3000, MT3600BE, MT5000, MT6000, X2000, X3000 and XE3000 up to 4.8.x. This affects an unknown part of the component Wi-Fi Timer Power-Schedule Feature. Executing a manipulation of the argument switch_power/restore_power can lead to os command injection. The attack can be launched remotely. The vendor explains: "After our investigation, we have confirmed that the vulnerability described (...) does indeed exist."
