Description
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.
