Summary

Initiative is a self-hosted project management platform. Versions of the application prior to 0.32.4 are vulnerable to Stored Cross-Site Scripting (XSS) in the document upload functionality. Any user with upload permissions within the "Initiatives" section can upload a malicious `.html` or `.htm` file as a document. Because the uploaded HTML file is served under the application's origin without proper sandboxing, the embedded JavaScript executes in the context of the application. As a result, authentication tokens, session cookies, or other sensitive data can be exfiltrated to an attacker-controlled server. Additionally, since the uploaded file is hosted under the application's domain, simply sharing the direct file link may result in execution of the malicious script when accessed. Versio
