CVE-2022-40257
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 · uneditedAn HTML injection vulnerability exists in CERT/CC VINCE software prior to 1.50.4. An authenticated attacker can inject arbitrary HTML via a crafted email with HTML content in the Subject field.
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 confidenceAn HTML injection vulnerability in CERT/CC VINCE software versions prior to 1.50.4 allows authenticated attackers to inject arbitrary HTML via the Subject field in crafted emails. The application fails to properly sanitize or encode user input in the email Subject field before rendering it, leading to HTML injection.

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.
-
Determine VINCE software versionLocate the version number in the VINCE installation - typically found in the application header, about page, or version configuration file (often named version.py, __init__.py, or shown in the admin interface under system information)Affected if The installed version is lower than 1.50.4 (e.g., 1.50.3, 1.50.2, 1.49.x, etc.)
-
Confirm email module is activeVerify that the email sending functionality is enabled and accessible in VINCE - check if the system has email notification capabilities configured and that users can compose or trigger outgoing emails through the platformAffected if Email functionality is enabled and users can input custom subject lines for outgoing messages
-
Identify user input points for email SubjectLocate the web interface or API endpoint where email Subject fields accept user input - this typically appears in contact forms, vulnerability report submissions, or notification settings where users can specify a subject lineAffected if The Subject field accepts free-form text input without visible sanitization or encoding controls visible in the UI
-
Test subject field rendering behaviorSubmit a test email with HTML characters in the Subject field (such as <script>alert(1)</script> or <b>test</b>) and examine the rendered output in the email client or application logs to see if HTML is rendered or strippedAffected if HTML tags in the Subject field are rendered as-is rather than being encoded or stripped from the output
You are affected if VINCE version is below 1.50.4 and the email Subject field accepts user input that gets rendered without sanitization.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.50.4
Upgrade to VINCE version 1.50.4 or later which contains the fix for proper input sanitization of the email Subject field.
1.50.4
- Verify current Vince installation version
- Review release notes for version 1.50.4 to understand security fixes
- Backup current installation and database
- Upgrade Vince to version 1.50.4 or later
- Verify the upgrade was successful
- Confirm the HTML injection vulnerability in the Subject field is remediated
