CVE-2026-49200 is a broken access control / information exposure vulnerability affecting Acer Wave 7 mesh routers running firmware T7c_GBL_1.01.000055 and earlier. The device’s web interface exposes the internal log file acer_cgi.log without authentication. That log file contains cleartext login credentials for both the router’s web management interface and Telnet service. As a result, a remote unauthenticated attacker can directly retrieve valid administrative credentials from the exposed log and then use them to access the device.
