## Check your systems with an agent

```text
Check whether my systems are affected by CVE-2026-91874 (Dell OpenManage Ansible Modules, versions 5.0.0 through 10.0.3, contains an Improper Certificate Validation vulnerability in the…), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

What cve.now has for CVE-2026-91874 (entry last updated 2026-11-11):
Affected:
- Dell OpenManage Ansible Modules: version range not reported
Fixed versions: 11.0.0 or later.
Conditions (all must be true for the bug to be hit):
- Dell OpenManage Ansible Modules versions 5.0.0 through 10.0.3 with the iDRACConnection component (source: https://www.dell.com/support/kbdoc/en-in/000515420/dsa-2026-432-security-update-for-dell-ansible-server-vulnerabilities)
- iDRACConnection used without certificate verification explicitly enabled (validate_certs=True) (source: https://www.dell.com/support/kbdoc/en-in/000515420/dsa-2026-432-security-update-for-dell-ansible-server-vulnerabilities)
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
Attacker needs: network access, no login, no user action.
Workaround: Explicitly enable certificate verification by setting validate_certs=True when using iDRACConnection. (source: https://www.dell.com/support/kbdoc/en-in/000515420/dsa-2026-432-security-update-for-dell-ansible-server-vulnerabilities)
CISA KEV: CVE-2026-91874 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-91874 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.

## FAQ

### Is CVE-2026-91874 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: https://cve.now/CVE-2026-91874

### What does this mean?

The iDRACConnection component does not properly validate certificates, which 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?

Versions 5.0.0 through 10.0.3 are affected when iDRACConnection is used without certificate verification explicitly enabled, meaning validate_certs=True is not set. To check, look at the installed version of the OpenManage Ansible Modules and the validate_certs setting in playbooks that use iDRACConnection.

### How do I fix CVE-2026-91874?

Upgrade to version 11.0.0 or later. Until the upgrade is done, set validate_certs=True when using iDRACConnection.
