Fix for Open Redirect vulnerability in OpenKortex auth module

Vulnerability Overview The attached screenshot displays a commit record regarding the remediation of an insecure redirection vulnerability. The vulnerability involves insufficient validation of user-provided redirection URLs during the authentication and redirection process, potentially leading to malicious redirection attacks. Scope of Impact Affected Modules: and Affected Functionality: User login, registration, password reset, and other features involving redirection. Remediation Plan 1. Introduction of Security Functions: - The function was introduced in to securely process redirection URLs. - The function was also introduced in . 2. Specific Modifications: - In , the parameters in multiple functions were securely processed to ensure they conform to the expected format. - In , similar validation and processing were applied to the parameter.
