CVE-2026-93676

3.2 lowEPSS 0.1%

Low (3.2). EPSS 0.1% chance of exploitation in the next 30 days.

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.
