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
Improper input validation and output encoding in all comments fields, in M-Files Hubshare before 3.3.10.9 allows authenticated attackers to introduce cross-site scripting attacks via specially crafted comments.

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

M-Files Hubshare before version 3.3.10.9 contains a stored cross-site scripting (XSS) vulnerability in comment fields due to improper input validation and insufficient output encoding. Authenticated attackers can inject malicious JavaScript payloads into comment fields that execute when other users view the comments.

MitigationUpgrade M-Files Hubshare to version 3.3.10.9 or later. As a temporary mitigation, restrict comment creation privileges to trusted users only and implement Content Security Policy headers to limit script execution.

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 installed M-Files Hubshare version
    Access the M-Files Hubshare administration interface or check the product's About/Version information panel typically found in the settings or system information page
    Affected if The displayed version number is lower than 3.3.10.9
  2. Verify comment functionality is enabled
    Navigate to the user permissions or workflow configuration section in the M-Files Hubshare administration console and check whether comment creation or posting is permitted for standard users
    Affected if Comment fields are available and users have permission to add comments
  3. Confirm user authentication is active
    Check that the M-Files Hubshare system is configured to allow user logins and that standard authenticated users can access the platform
    Affected if Standard authenticated users can log in and access comment-enabled areas of the application
  4. Inspect comment field input handling
    As an authenticated user, attempt to insert HTML or JavaScript characters (<, >, script tags) into a comment field and save it, then view the comment as a different user to observe if the input is rendered as raw code or executed
    Affected if Injected script tags or HTML elements in comments execute when viewed by other users rather than being displayed as plain text

A user is affected if M-Files Hubshare version is below 3.3.10.9 and the comment feature is accessible to authenticated users who can inject and execute malicious JavaScript code.
