CVE-2026-13243 Overview
CVE-2026-13243 is a Cross-Site Request Forgery (CSRF) vulnerability [CWE-352] affecting the Drupal Salesforce Suite contributed module. The flaw affects all Salesforce Suite versions from 0.0.0 through 5.1.3. An attacker can trick an authenticated administrator into submitting unintended state-changing requests to the Drupal application. Successful exploitation results in limited impact to confidentiality and integrity, with no direct impact to availability. The issue is tracked in the Drupal Security Advisory SA-CONTRIB-2026-063.
Critical Impact
An authenticated victim visiting an attacker-controlled page can be coerced into performing Salesforce Suite actions in Drupal without their consent.
Affected Products
- Drupal Salesforce Suite module versions 0.0.0 through 5.1.3
- Drupal sites integrating with Salesforce via the Salesforce Suite contributed module
- Any Drupal deployment where authenticated users hold Salesforce Suite privileges

Technical Details for CVE-2026-13243
Vulnerability Analysis
The Salesforce Suite module exposes state-changing endpoints that do not adequately verify the origin or intent of incoming requests. When a privileged Drupal user is authenticated and visits a malicious page, that page can issue a forged request to the Drupal site. The browser automatically includes the user's session cookie, and the server processes the request as legitimate. The exploit requires the victim to be signed in and to interact with attacker-controlled content, which raises the attack complexity.
The scope of impact is bounded by the privileges of the targeted user. An attacker cannot directly read data returned by the forged request, but can trigger configuration changes or trigger Salesforce integration actions within the victim's permission set. The vulnerability does not require the attacker to hold Drupal credentials.
Root Cause
The root cause is missing or insufficient CSRF token validation on sensitive routes exposed by the Salesforce Suite module. Drupal provides built-in CSRF protection primitives, but the affected endpoints did not consistently enforce them. This deviation from Drupal's form API and route access requirements enables cross-origin request submission with the victim's credentials.
Attack Vector
The attack vector is network-based and requires user interaction. An attacker hosts a crafted HTML page containing an auto-submitting form or JavaScript that targets a vulnerable Salesforce Suite endpoint. When an authenticated Drupal administrator visits the page, the browser transmits the request with valid session cookies. The Drupal application executes the request under the victim's identity.
No verified public exploit code is available. Refer to the Drupal Security Advisory SA-CONTRIB-2026-063 for further technical detail.
Detection Methods for CVE-2026-13243
Indicators of Compromise
- Unexpected configuration changes to Salesforce Suite mappings, field maps, or authentication providers
- Salesforce Suite administrative actions performed outside normal maintenance windows or from unusual client IPs
- Web server access logs showing POST requests to Salesforce Suite routes with Referer headers pointing to external, untrusted origins
Detection Strategies
- Review Drupal watchdog and dblog entries for Salesforce Suite administrative actions and correlate them with authenticated user sessions
- Inspect HTTP logs for state-changing requests to Salesforce Suite endpoints that lack a valid same-origin Referer or Origin header
- Compare the installed Salesforce Suite module version against the fixed release identified in the vendor advisory
Monitoring Recommendations
- Enable verbose logging on Drupal user role and permission changes, plus Salesforce Suite configuration changes
- Alert on anomalous administrative activity originating from browser sessions that immediately follow visits to external domains
- Monitor outbound Salesforce API calls initiated by Drupal for unusual volume or off-hours patterns
How to Mitigate CVE-2026-13243
Immediate Actions Required
- Upgrade the Drupal Salesforce Suite module to the fixed release documented in SA-CONTRIB-2026-063
- Audit user accounts holding Salesforce Suite administrative permissions and remove unnecessary privileges
- Force logout of active administrative sessions and rotate any exposed API credentials or OAuth tokens used by the integration
Patch Information
Drupal has released a fixed version of the Salesforce Suite module addressing versions 0.0.0 through 5.1.3. Site operators should apply the patched release identified in the Drupal Security Advisory using standard Drupal module update procedures such as composer update followed by drush updatedb and cache rebuild.
Workarounds
- Restrict Salesforce Suite administrative routes to trusted IP ranges via web server or reverse proxy access controls until the patch is applied
- Require administrators to use a dedicated browser or session isolation when performing Salesforce Suite tasks to reduce cross-origin exposure
- Enforce strict SameSite=Strict or SameSite=Lax attributes on Drupal session cookies to limit cross-site request submission
# Update the Salesforce Suite module using Composer and Drush
composer update drupal/salesforce --with-dependencies
vendor/bin/drush updatedb -y
vendor/bin/drush cache:rebuild
