Description

An authorization flaw was found in openstack-barbican. The default policy rules for the secret metadata API allowed any authenticated user to add, modify, or delete metadata from any secret regardless of ownership. This flaw allows an attacker on the network to modify or delete protected data, causing a denial of service by consuming protected resources.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update barbican to 14.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-23451 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.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
