CVE-2026-45430 Details
Description
The 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.
A cross-site request forgery (CSRF) vulnerability has been identified in the Salesforce module for Backdrop CMS, affecting all versions prior to 1.x-1.0.1. The vulnerability arises because the module does not properly generate or validate a cryptographically random 'state' parameter, leaving the authorization flow susceptible to CSRF attacks. Additionally, the OAuth callback can be accessed by most authenticated users and potentially anonymous users, depending on the site's configuration.
Users are advised to upgrade to the latest version of the Salesforce module. The updated version can be downloaded from the Salesforce project page on the Backdrop CMS website.
