Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Dell PowerScale OneFS, versions prior to 9.10.1.6 and versions 9.11.0.0 through 9.12.0.1, contains an uncontrolled search path element vulnerability. A high privileged attacker with local access could potentially exploit this vulnerability, leading to denial of service, elevation of privileges, and information disclosure.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Dell PowerScale OneFS contains an uncontrolled search path element vulnerability where the application uses a path that can be manipulated by a high-privileged local attacker. This could allow the attacker to inject malicious code through the search path, potentially leading to denial of service, privilege escalation, or information disclosure.

MitigationApply the vendor-provided patches by upgrading to version 9.10.1.6 or later, or version 9.12.0.2 or later, as specified in Dell's security advisory.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Determine PowerScale OneFS version
    Run the command 'isi version' or 'isi_get_versions' on the OneFS CLI to retrieve the installed OneFS version number
    Affected if The displayed version falls below 9.10.1.6, or is between 9.11.0.0 and 9.12.x (inclusive of 9.12.0.0 through 9.12.0.1)
  2. Confirm OneFS build details
    Run 'isi status' or check /etc/OneFS/onefs_version for the full build string including the minor version and patch level
    Affected if The exact version string does not match 9.10.1.6 or later, or 9.12.0.2 or later, or 9.13.0.0 or later
  3. Identify if this is a clustered node
    Run 'isi_cluster_nodes' or access the web admin console under Cluster > Hardware to list all nodes in the cluster
    Affected if All nodes in the cluster are running an affected version (the vulnerability affects the entire cluster)
  4. Review recent security patches
    Check /var/log/onefs_messages or run 'isi_patch' status to see if security patches have been applied
    Affected if No security patches related to CVE-2026-22270 or the uncontrolled search path fix have been installed

Your environment is affected if the installed PowerScale OneFS version is below 9.10.1.6, or falls between 9.11.0.0 and 9.12.0.1, or is 9.12.0.x (with x less than 2)

Upgrade available Upgrade to 9.10.1.6 / 9.13.0.0 or later
Fixed in 9.10.1.69.13.0.0
Interim mitigation

Apply the vendor-provided patches by upgrading to version 9.10.1.6 or later, or version 9.12.0.2 or later, as specified in Dell's security advisory.

Recommended fix High confidence

Upgrade to OneFS 9.10.1.6 or 9.13.0.0 (or later)

  1. 1. Identify the current PowerScale OneFS version using 'isi version' or through the web UI under Cluster > Overview
  2. 2. Schedule a maintenance window as the upgrade may require cluster downtime
  3. 3. Back up the cluster configuration and ensure you have a valid snapshot
  4. 4. Download the fixed OneFS ISO image (9.10.1.6 or 9.13.0.0 or later) from Dell Support portal
  5. 5. Upload the ISO to the cluster using 'isi firmware' or through the web UI (Cluster > Updates > Firmware)
  6. 6. Verify the firmware package integrity before proceeding
  7. 7. Initiate the upgrade using 'isi firmware update' command or through the web UI
  8. 8. Monitor the upgrade progress and ensure all nodes complete the update
