CVE-2022-26317
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability has been identified in Mendix Applications using Mendix 7 (All versions < V7.23.29). When returning the result of a completed Microflow execution call the affected framework does not correctly verify, if the request was initially made by the user requesting the result. Together with predictable identifiers for Microflow execution calls, this could allow a malicious attacker to retrieve information about arbitrary Microflow execution calls made by users within the affected system.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is an access control vulnerability in Mendix 7 where the framework fails to properly verify that the user requesting the result of a microflow execution is the same user who initiated it. Combined with predictable identifiers for microflow calls, an attacker can retrieve information about arbitrary microflow executions made by other users.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Mendix application versionCheck the runtime version of the Mendix application by inspecting the deployment metadata, model version information, or the /rest-doc/ endpoint if exposed. This is typically visible in the application startup logs or modeler project settings.Affected if The installed Mendix version is any version below 7.23.29 (e.g., 7.23.28, 7.22.x, 7.21.x, etc.)
-
Confirm Mendix 7 lineageVerify the application is running on Mendix 7.x platform rather than Mendix 8.x, 9.x, or 10.x. This distinction is visible in the version string (e.g., 7.23.0 indicates Mendix 7).Affected if The application uses Mendix 7.x framework regardless of the minor version within that lineage
-
Determine if microflows are exposedInspect the published REST or SOAP services in the Mendix application. Microflows exposed as published web services or REST operations are the attack vector for this vulnerability.Affected if The application exposes microflows as callable services via the Mendix WS/* or REST publish features, and the version is below 7.23.29
The environment is affected if the Mendix application runs on version 7.x below 7.23.29 and exposes microflows as callable services, allowing unauthorized retrieval of execution results from other users' microflow calls.

dbcve · scoped7.23.29
Upgrade Mendix Applications to version V7.23.29 or later, which contains the proper request-origin verification for microflow execution results.
Mendix 7.23.29 or later
- Identify your current Mendix 7 version by checking the Modeler or project settings
- Download Mendix version 7.23.29 or later from the Mendix release archive
- Upgrade your Mendix Studio Pro to the new version
- Open your application in the upgraded Studio Pro and allow the migration to complete
- Test all Microflow functionality thoroughly in a non-production environment
- Deploy the upgraded application to production
