Wyse Management Suite: Acceptance of Extraneous Untrusted Data With Trusted Data
CVE-2026-41120 is a critical-severity acceptance of extraneous untrusted data with trusted data vulnerability in Wyse Management Suite from Dell, with a CVSS 3.1 base score of 9.8 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 Version 5.5 HF1 or later as the first without the flaw, so updating Wyse Management Suite to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.39% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Wyse Management Suite to Version 5.5 HF1 or later 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.
