Check your systems with an agent
Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.
Check whether my systems are affected by CVE-2026-95646 (Authenticated Command Injection), 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-2026-95646 (entry last updated 2026-11-10): Affected: - Zohocorp DDI Central: fixed in 6500 Fixed versions: 6500. Conditions (all must be true for the bug to be hit): - Cisco IOS DHCP configuration functionality in DDI Central (source: https://www.manageengine.com/dns-dhcp-ipam/security-updates/security-updates.html) Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory. Attacker needs: network access, high-privilege login, no user action. CISA KEV: CVE-2026-95646 is not listed as of cve.now's last read. This KEV status is for CVE-2026-95646 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.manageengine.com/dns-dhcp-ipam/security-updates/security-updates.html 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-2026-95646
Is CVE-2026-95646 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?
Cluster-scoped operators can enter specially crafted Unicode characters in the Cisco IOS DHCP configuration feature, which causes the device to execute commands that were not intended.Source: manageengine.com
Which versions are affected by CVE-2026-95646?
DDI Central: before 6500.Source: cve.now feed data
Am I affected, and how do I check?
The vulnerable range is DDI Central from the first release up to, but not including, Build 6500, in setups that use the Cisco IOS DHCP configuration functionality. A reader can check the installed DDI Central build number and whether that DHCP configuration feature is in use.Source: manageengine.com
How do I fix CVE-2026-95646?
Upgrade DDI Central to Build 6500 or later, which contains the fix.Source: manageengine.com
