Echo: xdg-dbus-proxy: security update to 0.1.6-1+deb13u3

high Tenable Self-Hosted Container Security Plugin ID 458596

Description

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

 - An incorrect implementation of message filtering in xdg-dbus-proxy versions before 0.1.9 allows an
 attacker to bypass the intended message filtering on the D-Bus session bus by setting a reply serial
 number on non-reply messages. A malicious or compromised Flatpak app could use this to achieve arbitrary
 code execution outside its sandbox. xdg-dbus-proxy was designed to be part of the sandbox boundary for
 Flatpak, but it is released as a separate project and is sometimes used by other app frameworks such as
 Firejail. (CVE-2026-94422)

Solution

Update the xdg-dbus-proxy library and its related packages to version 0.1.6-1+deb13u3 or later.
