What is CVE-2026-0620?

The TP-Link Archer AXE75 V1, when set up as an L2TP/IPSec VPN server, may allow connections using L2TP without the necessary IPSec encryption, even if IPSec protection is enabled. This misconfiguration can result in VPN sessions being unencrypted, thereby exposing sensitive data in transit to unauthorized access and potential interception, which compromises the overall confidentiality of the communication.
