Description

Improper Authentication vulnerability in Apache Ozone.

The vulnerability allows an attacker to download metadata internal to the Storage Container Manager service without proper authentication. The attacker is not allowed to do any modification within the Ozone Storage Container Manager service using this vulnerability. The accessible metadata does not contain sensitive information that can be used to exploit the system later on, and the accessible data does not make it possible to gain access to actual user data within Ozone. This issue affects Apache Ozone: 1.2.0 and subsequent releases up until 1.3.0.

Users are recommended to upgrade to version 1.4.0, which fixes the issue.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update org.apache.ozone:ozone-main to 1.4.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6726-2rx3-cgwh 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.
