CVE-2026-93676  (opens in a new tab)

How to fix?

Upgrade Debian:unstable xdg-dbus-proxy to version 0.1.8-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream xdg-dbus-proxy package and not the xdg-dbus-proxy package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

xdg-dbus-proxy incorrectly filters D-Bus broadcast messages, bypassing configured path, interface, and member restrictions. This allows a sandboxed Flatpak application to intercept broadcast signals on the D-Bus session bus and AT-SPI bus that should be restricted, potentially exposing sensitive information to unauthorized applications.
