CISA KEV: CVE-2026-91879 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-91879 only. If you also check another CVE, look up its own KEV status; never assume it from this one.
How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.
Verify against the linked advisories before concluding, and cite the date you read each one:
- https://www.dell.com/support/kbdoc/en-in/000515434/dsa-2026-433-security-update-for-dell-terraform-provider-for-dell-storage-multiple-vulnerabilities
Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.
Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.

Questions about CVE-2026-91879
Is CVE-2026-91879 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
The flaw can lead to information exposure and unauthorized access. The checked facts do not describe the mechanism in more detail.Source: dell.com
Am I affected, and how do I check?
Dell Terraform Provider for ObjectScale versions prior to 1.1.1 and Dell Terraform Provider for PowerStore versions 1.2.1 through 1.3.0 are listed as affected. A reader can check which provider version their Terraform configuration uses.Source: dell.com
How do I fix CVE-2026-91879?
For the ObjectScale provider, the affected range ends before 1.1.1, so moving to 1.1.1 or later addresses the listed range. The checked facts do not give a fixed PowerStore version, so the Dell advisory should be checked for one.Source: dell.com
What if there's no patch?
The checked facts do not list a workaround or interim mitigation. The Dell advisory should be consulted for guidance while no fix is available.Source: dell.com
