# CVE-2026-5674: Pipewire: pipewire: sandbox escape and arbitrary code execution via malicious library loading Status: published. Published: 2026-07-16. Updated: 2026-11-04. A flaw was found in PipeWire, a multimedia server. This vulnerability allows an attacker to escape sandboxed applications, such as Flatpak, by exploiting PipeWire's PulseAudio compatibility layer. An attacker with minimal permissions within a sandboxed environment can load a malicious library, leading to arbitrary code execution outside the sandbox and potential compromise of the user's system. ## Remediation - workaround: To mitigate this issue, restrict containerized applications from accessing the PulseAudio socket or writing to host-visible paths. Additionally, configure PipeWire to prevent module loading by setting `pulse.allow-module-loading = false` in the PipeWire PulseAudio configuration. Alternatively, restrict the `dlopen()` paths for `module-ladspa-sink` to trusted system directories like `/usr/lib/ladspa/` and `/usr/lib64/ladspa/`. Applying these changes may require restarting the PipeWire service to take effect, which could impact audio functionality.
