What is CVE-2026-39940?

ChurchCRM, an open-source church management system, contains a vulnerability that enables authenticated users to be redirected to arbitrary URLs when they interact with certain links within the application. Specifically, prior to version 7.0.0, the application did not adequately validate links created for the 'Cancel' button, exposing users to potential phishing attacks or malicious redirect attempts. This issue affects multiple locations within the application, particularly where 'linkBack' functions are employed. Users are encouraged to upgrade to the latest version to mitigate this risk.

Affected Version(s)
