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 Neutralization of Argument Delimiters in a Command ('Argument Injection') vulnerability in Salesforce Marketing Cloud Engagement allows Web Services Protocol Manipulation. This issue affects Marketing Cloud Engagement: before January 30th, 2026.

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 · moderate confidence

An argument injection vulnerability exists in Salesforce Marketing Cloud Engagement's web services API. Attackers can manipulate argument delimiters in web service requests to inject unauthorized arguments into commands, potentially allowing execution of unintended operations through the API interface.

MitigationApply the vendor patch released January 30th, 2026 or later. Review API access logs for signs of exploitation and ensure web services integrations follow least-privilege principles.

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. Confirm Salesforce Marketing Cloud Engagement usage
    Identify whether your environment uses Salesforce Marketing Cloud Engagement by reviewing your integrations, connected applications, or administrative console for this product.
    Affected if Your organization uses Salesforce Marketing Cloud Engagement as part of your marketing or data operations.
  2. Identify installed product version
    Locate the version number of your Salesforce Marketing Cloud Engagement instance through the administration panel, release notes, or by querying the system profile information.
    Affected if The installed version is earlier than the January 30th, 2026 patch release.
  3. Verify web services API is enabled
    Check your Salesforce Marketing Cloud Engagement administrative settings to confirm whether the web services API interface is exposed or enabled for your integration.
    Affected if The web services API is enabled and accessible to your integration accounts.
  4. Review API access logs for argument injection patterns
    Examine your web services API access logs for requests containing unusual argument delimiters, unexpected parameter additions, or suspicious command patterns that may indicate exploitation attempts.
    Affected if Logs show requests with manipulated argument delimiters or injected parameters not part of intended API calls.
  5. Audit API integration accounts
    Review which integration accounts or API keys have access to the web services API and verify they follow least-privilege principles with minimal required permissions.
    Affected if API integrations have broader permissions than necessary for their intended functions.

You are affected if you use Salesforce Marketing Cloud Engagement with the web services API enabled and your version predates the January 30th, 2026 patch, or if your API logs show evidence of argument injection attempts.
