Server: Improper Enforcement of Behavioral Workflow
CVE-2026-3130 is a critical-severity improper enforcement of behavioral workflow vulnerability in Server from Devolutions, 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 2025.3.16 as the first without the flaw, so updating Server to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.49% 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 Server to 2025.3.16 or a later version.
- Update Devolutions Server to 2025.3.16.0 or a later version.
- Read the advisory on devolutions.net 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.

The underlying weakness: Improper Enforcement of Behavioral Workflow
