title: Local Privilege Escalation via the ‘streamfwd’ program in Splunk App for Stream
description: In Splunk App for Stream versions below 8.1.1, a low-privileged user could use a vulnerability in the streamfwd process within the Splunk App for Stream to escalate their privileges on the machine that runs the Splunk Enterprise instance, up to and including the root user.
problem types: The software does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
