This warning has been issued under the ID CIVN-2026-0034.
According to CERT-In, this security flaw affects certain TP-Link Archer router models. These include the TP-Link Archer BE400 V1, which is running on firmware version 1.1.0 (Build 20250710 rel.14914) or earlier, and the TP-Link Archer AXE75 v1.6, which is running on firmware version 1.1.0 (Build 20250710 rel.14914) or earlier. These routers are used extensively in homes as well as offices and institutions.

If a remote attacker successfully takes advantage of these flaws, he can delete important files from the router. Apart from this, Internet connection can also be shut down by crashing the router through DoS attack.
