CVE-2026-45430
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 · uneditedThe Salesforce module before 1.x-1.0.1 for Backdrop CMS does not properly use a random state parameter to protect the authorization flow against CSRF attacks.
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 confidenceThe Salesforce module for Backdrop CMS fails to implement a proper random state parameter in its OAuth 2.0 authorization flow, allowing cross-site request forgery attacks where an attacker can intercept or manipulate the OAuth authorization process by tricking users into completing an authorization request initiated by the attacker.

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.
-
Identify if Salesforce module is installedCheck for the Salesforce module directory in the Backdrop CMS installation (typically under /modules/salesforce or via Drush/Backdrop admin interface)Affected if The Salesforce module directory exists and the module is enabled in Backdrop CMS
-
Determine Salesforce module versionCheck the module's .info file or composer.json for the version number (usually in the module directory or via Backdrop admin interface at admin/modules)Affected if The installed version is below 1.0.1 (e.g., 1.0.0 or earlier)
-
Verify OAuth connection is configuredCheck if Salesforce OAuth is configured in the module settings (typically at admin/config/services/salesforce or via the module's connection settings)Affected if OAuth authorization to Salesforce is configured and enabled for user authentication
-
Inspect state parameter implementationReview the OAuth authorization code in the Salesforce module for proper state parameter generation and validation (look for 'state' parameter in authorization URL generation and validation logic)Affected if The code lacks cryptographically random state parameter generation or validation during OAuth flow
A Backdrop CMS installation is affected if the Salesforce module version is 1.0.0 or earlier and OAuth authorization to Salesforce is configured and in use.
Generated from the published advisory. Verify against your own configuration.
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 · scopedUpdate the Salesforce module to version 1.x-1.0.1 or later which properly generates and validates a cryptographically random state parameter during the OAuth authorization flow.
Salesforce module version 1.x-1.0.1 for Backdrop CMS
- Backup your Backdrop CMS site database and files
- Navigate to the Backdrop CMS module management interface or use Drush to update the Salesforce module
- Update the Salesforce module to version 1.x-1.0.1 or later
- Clear all Backdrop CMS caches (via admin interface or Drush command: `drush cc all`)
- Verify the update was successful by checking the module version in the modules list
- Test the Salesforce OAuth/authorization flow to confirm the state parameter is now properly implemented
