Summary

GNU Mailman versions prior to 2.1.30 are susceptible to a Cross-Site Scripting (XSS) vulnerability caused by mishandling of file attachments with the '.obj' extension. The lack of proper MIME type designation may lead the browser to misinterpret the content as HTML, enabling the execution of unexpected JavaScript code. This security flaw can potentially allow attackers to execute scripts in the context of users accessing the list archive, posing a significant security risk.
