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 · unedited
Stored XSS in M-Files Web versions from 25.1.14445.5 to 25.2.14524.4 allows an authenticated user to run scripts

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 confidence

Stored XSS vulnerability in M-Files Web allows authenticated users to inject malicious scripts that execute in other users' browsers. The flaw affects versions 25.1.14445.5 through 25.2.14524.4, where user-supplied input is insufficiently sanitized before being stored and rendered.

MitigationUpgrade M-Files Web to a version beyond 25.2.14524.4. Implement input validation, output encoding, and consider Content Security Policy headers as defense-in-depth measures.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if M-Files Web is deployed
    Check for M-Files web server components by reviewing installed applications, services, or IIS sites if applicable. Look for M-Files-related web directories or services.
    Affected if M-Files Web component is present in the environment
  2. Determine M-Files Web version
    Locate the M-Files version information typically found in the M-Files server administration, installer properties, or registry keys under the M-Files installation directory. The version follows the format XX.X.XXXXX.X
    Affected if Version falls within 25.1.14445.5 through 25.2.14524.4 inclusive
  3. Verify web interface is enabled
    Confirm that the M-Files Web access service is running and the web interface is accessible to users. Check M-Files Server service status and web vault configuration.
    Affected if Web interface is enabled and accessible to authenticated users
  4. Confirm authentication is active
    Verify that user authentication is configured and active for the M-Files Web portal, as the vulnerability requires authenticated user access.
    Affected if User authentication is enabled for the web interface

The environment is affected if M-Files Web is installed with a version between 25.1.14445.5 and 25.2.14524.4 and the web interface with authentication is enabled.
