PowerScale OneFS: Insufficient Logging
CVE-2026-22279 is a high-severity insufficient logging vulnerability in PowerScale OneFS from Dell, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 9.13.0.0 as the first without the flaw, so updating PowerScale OneFS to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.27% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update PowerScale OneFS to 9.13.0.0 or a later version.
- Read the advisory on dell.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Dell PowerScale OneFS, versions prior 9.13.0.0, contains an insufficient logging vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to information tampering.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Insufficient Logging
When a security-critical event occurs, the product either does not record the event or omits important details about the event when logging it.
How developers prevent this class of flaw
- Use a centralized logging mechanism that supports multiple levels of detail.
- Ensure that all security-related successes and failures can be logged. When storing data in the cloud (e.g., AWS S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to enable and capture detailed logging information.
- Be sure to set the level of logging appropriately in a production environment. Sufficient data should be logged to enable system administrators to detect attacks, diagnose errors, and recover from attacks. At the same time, logging too much data (CWE-779) can cause the same problems, including unexpected costs when using a cloud environment.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
