CVE-2026-27102
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 · uneditedDell PowerScale OneFS, versions 9.5.0.0 through 9.10.1.6 and versions 9.11.0.0 through 9.13.0.1, contains an incorrect privilege assignment vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to elevation of privileges.
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 confidenceDell PowerScale OneFS versions 9.5.0.0-9.10.1.6 and 9.11.0.0-9.13.0.1 contain an incorrect privilege assignment vulnerability allowing a low-privileged local attacker to escalate privileges to higher authority levels.

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 checksWork through these to decide whether this CVE applies to you.
-
Determine PowerScale OneFS versionRun 'isi version' or check the OneFS web UI dashboard for the current firmware versionAffected if Version is 9.5.0.0-9.10.1.6 or 9.11.0.0-9.13.0.1 (unpatched)
-
Audit local user accountsRun 'isi auth users list' to enumerate all local users and check for unexpected accounts with elevated privilegesAffected if Any unauthorized or unexpected accounts exist with administrator or elevated privileges
-
Review privilege assignmentsRun 'isi auth roles list' and compare role mappings against documented baseline configurationsAffected if Any roles are assigned to users outside of documented baseline
-
Check for recent privilege escalation eventsReview system audit logs in /var/log/ for privilege-related events or suspicious authentication activityAffected if Logs show unauthorized privilege changes or unexpected admin actions
Environment is affected if running an unpatched OneFS version (9.5.0.0-9.10.1.6 or 9.11.0.0-9.13.0.1) OR if unauthorized privileged accounts exist regardless of version.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped9.10.1.79.13.0.2
Apply vendor-supplied patches when available; until then, restrict local console access to trusted personnel only and monitor for unauthorized privilege escalation attempts.
OneFS 9.10.1.7+ (for 9.5-9.10.x users) or OneFS 9.13.0.2+ (for 9.11-9.13.x users)
- Verify current OneFS version by running 'isi version' or checking the WebUI dashboard
- Review Dell PowerScale OneFS upgrade documentation and release notes for version compatibility
- Ensure adequate backup of critical data and configuration exists
- Schedule maintenance window as upgrades require cluster downtime
- For 9.5.0.0-9.10.1.6: Upgrade to OneFS 9.10.1.7 or later (9.10.x latest recommended)
- For 9.11.0.0-9.13.0.1: Upgrade to OneFS 9.13.0.2 or later (9.13.x latest recommended)
- Perform upgrade using OneFS WebUI (Cluster Management > Upgrade) or CLI ('isi upgrade')
- Verify upgrade completion and test system functionality
