Critical Authentication Bypass Vulnerability in Acer Wave 7 Mesh Routers
Independent security researcher Gergo Pap has identified a maximum-severity zero-day vulnerability, designated CVE-2026-49200, affecting Acer Wave 7 mesh routers. The flaw is a broken access control vulnerability within the router management interface that allows unauthenticated remote attackers to access and retrieve router log archive files. These archives contain sensitive administrative credentials in plaintext format, facilitating complete system compromise. By exploiting this vector, an attacker can bypass standard authentication protocols, gain unauthorized access to the device, and execute lateral movement within the protected network. Acer is currently developing and deploying firmware updates to mitigate this critical information disclosure and access control risk.
