medium Tenable Cloud Security Plugin ID 442661

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 0.107.75, AdGuard Home's
 client-triggered DoQ forwarding path to a udp:// upstream reduced backend UDP DNS state by producing
 dns_id=0 or txid=0 and exposed a quoted-port ICMP source-port oracle, weakening DNS response matching for
 forwarded queries. This issue is fixed in version 0.107.75. (CVE-2026-47703)

Solution

Update the github.com/AdguardTeam/AdGuardHome library and its related packages to version 0.107.75 or later.
