CVE-2026-93676 is fixed in xdg-dbus-proxy on 1 platform, first by DEBIAN-CVE-2026-93676, released September 19, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
