CVE-2026-22279 is a medium-severity Insufficient Logging (CWE-778) vulnerability in Dell Powerscale Onefs. Its CVSS base score is 4.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data Manipulation (T1565); ranked at the 18.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 AU-2 (Event Logging) and AU-3 (Content of Audit Records).
Deeper analysis
CVE-2026-22279 is an insufficient logging vulnerability (CWE-778) in Dell PowerScale OneFS versions prior to 9.13.0.0. This flaw allows potential information tampering due to inadequate logging mechanisms.
An unauthenticated attacker with remote network access can exploit the vulnerability, which has low attack complexity but requires user interaction. Exploitation leads to low-impact integrity violations, enabling limited tampering with information, with no impact on confidentiality or availability. The CVSS v3.1 base score is 4.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N).
Dell's security advisory DSA-2026-049 addresses this vulnerability along with others in PowerScale OneFS, recommending an update to version 9.13.0.0 or later for mitigation.
