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
SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to versions 7.15.1 and 8.9.3, SuiteCRM contains an unauthenticated open redirect vulnerability in the WebToLead capture functionality. A user-supplied POST parameter is used as a redirect destination without validation, allowing attackers to redirect victims to arbitrary external websites. This vulnerability allows attackers to abuse the trusted SuiteCRM domain for phishing and social engineering attacks by redirecting users to malicious external websites. Versions 7.15.1 and 8.9.3 patch the issue.

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

SuiteCRM contains an unauthenticated open redirect vulnerability in the WebToLead capture functionality. Attackers can supply a malicious POST parameter that gets used as a redirect destination without validation, allowing redirection to arbitrary external websites while abusing the trusted SuiteCRM domain.

MitigationUpgrade to SuiteCRM versions 7.15.1 or 8.9.3 which contain the patch. Until then, implement temporary validation on redirect parameters in the WebToLead module.

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. Determine installed SuiteCRM version
    Locate the version number in the SuiteCRM admin panel (About section) or check the version.php /suite_version.php file in the installation root directory
    Affected if The version is less than 7.15.1 OR greater than or equal to 8.0.0 but less than 8.9.3
  2. Confirm WebToLead module is accessible
    Verify that the WebToLead capture form endpoint is reachable - typically at /index.php?module=WebToLeadCapture or similar path under the SuiteCRM root
    Affected if WebToLead functionality is enabled and accessible without authentication
  3. Identify the redirect parameter handling
    Examine the WebToLead form handling code - check if POST parameters controlling redirect behavior are validated before use in header() or similar redirect functions
    Affected if The code uses unchecked POST parameters for redirect destinations without validating they point to internal URLs

You are affected if your SuiteCRM version falls within the vulnerable ranges (< 7.15.1 or >= 8.0.0 to < 8.9.3) AND the WebToLead module is enabled and accessible without validation on redirect parameters.

Upgrade available Upgrade to 7.15.1 / 8.9.3 or later
Fixed in 7.15.18.9.3
Interim mitigation

Upgrade to SuiteCRM versions 7.15.1 or 8.9.3 which contain the patch. Until then, implement temporary validation on redirect parameters in the WebToLead module.

Recommended fix High confidence

SuiteCRM 7.15.1 (for 7.x versions) or SuiteCRM 8.9.3 (for 8.x versions)

  1. 1. Identify your current SuiteCRM version by accessing the admin panel or checking the version.php file in the installation directory
  2. 2. For SuiteCRM 7.x installations (version < 7.15.1): Upgrade to version 7.15.1 or later
  3. 3. For SuiteCRM 8.x installations (version >= 8.0.0 and < 8.9.3): Upgrade to version 8.9.3 or later
  4. 4. Download the appropriate upgrade package from the official SuiteCRM website (suitecrm.com) or GitHub repository
  5. 5. Follow the standard SuiteCRM upgrade procedure: backup your database and files, disable maintenance mode, extract the upgrade package, run the upgrade wizard
  6. 6. After completing the upgrade, clear the cache by deleting contents of the cache/ folder
  7. 7. Verify the WebToLead functionality works correctly with the new version
  8. 8. Test that the open redirect vulnerability is remediated by confirming that arbitrary external URLs can no longer be used as redirect destinations in the WebToLead form
Caveat Review the release notes for your target version to check for any breaking changes or required database migrations before upgrading
