Description

Impact

An abstract UNIX domain socket responsible for introspection is available without authentication locally to any user with access to the network namespace where the local juju agent is running.

On a juju controller agent, denial of service can be performed by using the /leases/revoke endpoint. Revoking leases in juju can cause availability issues.

On a juju machine agent that is hosting units, disabling the unit component can be performed using the /units endpoint with a "stop" action.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/juju/juju, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update github.com/juju/juju to 0.0.0-20240829052008-43f0fc59790d or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-xwgj-vpm9-q2rq is resolved across your whole dependency graph.

  3. Workarounds

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
