OpenManage Server Administrator Managed Node…: Server-Side Request Forgery
CVE-2026-81446 is a high-severity server-side request forgery vulnerability in OpenManage Server Administrator Managed Node (Patch) for Windows from Dell, with a CVSS 3.1 base score of 7.4 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version 11.1.0.3 as the first without the flaw, so updating OpenManage Server Administrator Managed Node (Patch) for Windows to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.37% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update OpenManage Server Administrator Managed Node (Patch) for Windows to 11.1.0.3 or a later version.
- Update OpenManage Server Administrator Managed Node for RHEL 8.10 to 11.1.0.3 or a later version.
- Update OpenManage Server Administrator Managed Node for RHEL 9.4 to 11.1.0.3 or a later version.
- Read the advisory on dell.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
Dell OpenManage Server Administrator, versions prior to 11.1.0.3, contains a Server-Side Request Forgery (SSRF) vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Server-side request forgery.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Server-Side Request Forgery
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
How developers prevent this class of flaw
- If there is a known list of applications, IP, hostname, and/or domains to which the product is allowed to communicate, then use allowlists to ensure that outgoing requests are restricted to these known entities. The allowlists could be in the application code or possibly enforced by firewalls or network segmentation.
- If the product is expected to be able to connect to arbitrary IP addresses or domains, consider using a denylist that includes private network addresses, internal domain names, etc. The denylist could be in the application code or possibly enforced by firewalls or network segmentation.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
