This KEV status is for CVE-2026-91875 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/000515420/dsa-2026-432-security-update-for-dell-ansible-server-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.

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: https://cve.now/CVE-2026-91875 ### What does this mean? The SessionAPI component does not properly validate certificates, so connections may not be checked for authenticity. This can lead to information exposure and unauthorized access. Source: https://www.dell.com/support/kbdoc/en-in/000515420/dsa-2026-432-security-update-for-dell-ansible-server-vulnerabilities ### Am I affected, and how do I check? Dell OpenManage Ansible Modules versions 9.2.0 through 10.0.3 with the SessionAPI component are affected. Check the installed module version and whether SessionAPI is in use. Source: https://www.dell.com/support/kbdoc/en-in/000515420/dsa-2026-432-security-update-for-dell-ansible-server-vulnerabilities ### How do I fix CVE-2026-91875? Upgrade to Dell OpenManage Ansible Modules version 11.0.0 or later. Until then, set validate_certs=True when using SessionAPI to explicitly enable certificate verification.
