CVE-2026-45430: Backdrop CMS Salesforce Module CSRF Risk
The National Vulnerability Database (NVD) has detailed CVE-2026-45430, a high-severity vulnerability (CVSS 7.1) affecting the Salesforce module for Backdrop CMS prior to version 1.x-1.0.1. This flaw stems from an improper implementation of a random state parameter, leaving the authorization flow vulnerable to Cross-Site Request Forgery (CSRF) attacks. Attackers could potentially exploit this to trick authenticated users into executing unwanted actions.
This isn’t just a theoretical bug. CSRF attacks, especially against integration modules like Salesforce, can lead to significant data manipulation or unauthorized access within the connected CRM system. The NVD highlights that successful exploitation requires user interaction (UI:R) and high attack complexity (AC:H), but the potential impact on confidentiality and integrity is high, with a moderate impact on availability.
For defenders, this means any organization running Backdrop CMS with the vulnerable Salesforce module needs to prioritize an update. While the NVD did not specify affected products beyond the module itself, the implications for data integrity and unauthorized control over CRM data are substantial. Patching this is a critical step to prevent attackers from leveraging user sessions.
What This Means For You
- If your organization uses Backdrop CMS with the Salesforce integration module, immediately check your version. Upgrade to Salesforce module 1.x-1.0.1 or later to mitigate CVE-2026-45430 and prevent potential CSRF attacks against your CRM data.
