CVE-2026-41448 [CRITICAL] – AdGuard Home, when started with the –glinet flag, contains an authentication bypass vulne

AdGuard Home, when started with the –glinet flag, contains an authentication bypass vulnerability that allows unauthenticated attackers to gain full admin access by supplying a path traversal sequence in the Admin-Token cookie, exploiting unsanitized string concatenation in the token file path construction within the authglinet middleware. Attackers can craft a request with a traversal payload in the Admin-Token header to redirect file reads to arbitrary paths.
