Description

An authenticated user with high privileges may trigger a denial‑of‑service condition in TP-Link Archer BE230 v1.2 by restoring a crafted configuration file containing an excessively long parameter. Restoring such a file can cause the device to become unresponsive, requiring a reboot to restore normal operation. This issue affects Archer BE230 v1.2 < 1.2.4 Build 20251218 rel.70420.
