CVE-2026-47128Public exploit

Sandbox escape via unmediated user D-Bus socket

Published Jul 20, 2026 · Updated Jul 20, 2026

Sandbox escape in nolabs nono before 0.55.0 allows local users to run unsandboxed commands through the per-user systemd D-Bus socket. The CLI policy layer and bundled profiles incompletely mediate concrete and abstract Unix domain sockets, so a confined process can ask systemd-run --user to launch an unsandboxed sibling. The process must already run inside a locally launched sandbox with command execution; escape regains only the launcher account’s existing file, process, and network authority, without cross-user or elevated access.
