About Devolutions Server
CVE-2026-14536 affects Devolutions Server, a product from Devolutions. Before acting, confirm where Devolutions Server runs in your estate, who owns it and whether it is reachable from the internet, because exposure decides real risk more than the score alone.
What the flaw is
In plain terms: Improper enforcement of a mandatory multi-factor authentication policy in Devolutions Server 2026.2.9.0 allows an attacker with valid user credentials to bypass the MFA Required policy and authenticate without completing multi-factor authentication. The problem occurs when DVLS encounters an invalid default MFA value.
The weakness class is Incorrect Authorization. The permission check exists but gets the answer wrong.
Based on its CVSS vector, the flaw can be reached over the network, needs some level of access, and needs no user interaction. Apply the vendor fix and confirm exposure on internet facing and business critical assets first.

How to detect it
- Inventory every instance of Devolutions Server and record the running version against the affected range above.
- Check external attack surface scans for internet facing instances of the component.
- Review logs on affected systems for unusual requests, errors or new processes around the vulnerable function.
- Confirm with an authenticated vulnerability scan once your scanner has a check for this CVE.
How to fix it
- Apply the fixed version of Devolutions Server named in the vendor advisory.
- If patching must wait, restrict network access to the affected service and put it behind authentication or a web application firewall rule.
- Rescan after the change to prove the exposure is gone, then close the ticket.

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.5.2-alpha.8 and 8.6.21, a vulnerability in Parse Server's query handling allows an authenticated or unauthenticated attacker to exfiltrate session tokens of other users by exploiting the redirectClassNameForKey query parameter. Exfiltrated session tokens can be used to take over user accounts. The vulnerability requires the attacker to be able to create or update an object with a new relation field, which depends on the Class-Level Permissions of at least one class. This vulnerability is fixed in 9.5.2-alpha.8 and 8.6.21.
Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes. Prior to 4.0.2 and 3.7.11, Workflow templates endpoints allow any client to retrieve WorkflowTemplates (and ClusterWorkflowTemplates).
