SCA: security update for github.com/AdguardTeam/AdGuardHome (GHSA-5fg6-wrq4-w5gh)

critical Tenable Self-Hosted Container Security Plugin ID 438701

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - AdGuard Home is a network-wide software for blocking ads and tracking. Prior to 0.107.73, an
 unauthenticated remote attacker can bypass all authentication in AdGuardHome by sending an HTTP/1.1
 request that requests an upgrade to HTTP/2 cleartext (h2c). Once the upgrade is accepted, the resulting
 HTTP/2 connection is handled by the inner mux, which has no authentication middleware attached. All
 subsequent HTTP/2 requests on that connection are processed as fully authenticated, regardless of whether
 any credentials were provided. This vulnerability is fixed in 0.107.73. (CVE-2026-32136)

Solution

Update the github.com/AdguardTeam/AdGuardHome library and its related packages to version 0.107.73 or later.
