Dell OpenManage Server Administrator Managed…: Use of Externally-Controlled Input to Select Classes or Code
CVE-2026-66269 is a high-severity use of externally-controlled input to select classes or code vulnerability in Dell OpenManage Server Administrator Managed Node (Patch) for Windows from Dell, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 11.1.0.3 as the first without the flaw, so updating Dell 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 0.2% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

Official description
Dell OpenManage Server Administrator, versions prior to 11.1.0.3, contains a Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Protection mechanism bypass.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Use of Externally-Controlled Input to Select Classes or Code
The product uses external input with reflection to select which classes or code to use, but it does not sufficiently prevent the input from selecting improper classes or code.
How developers prevent this class of flaw
- Refactor your code to avoid using reflection.
- Do not use user-controlled inputs to select and load classes or code.
- Apply strict input validation by using allowlists or indirect selection to ensure that the user is only selecting allowable classes or code.
