Description

OpenStack Identity (Keystone) Folsom 2012.2.4 and earlier, Grizzly before 2013.1.1, and Havana does not immediately revoke the authentication token when deleting a user through the Keystone v2 API, which allows remote authenticated users to retain access via the token.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update keystone to 8.0.0a0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hj89-qmx9-8qmh is resolved across your whole dependency graph.

  3. Workarounds

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
