It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-2068 advisory.

    A flaw was found in gnome-remote-desktop as shipped in Red Hat Enterprise Linux. When the daemon is     running in system mode with RDP enabled, the incoming connection handler bypasses the connection     throttler, allowing an unauthenticated remote attacker to open many parallel pre-authentication     connections to the RDP listener. This can accumulate accepted sockets and pending routing-token operations     until timeout, exhausting resources and preventing legitimate users from establishing RDP sessions. This     issue does not affect the upstream version. (CVE-2026-18358)
