foobarwidget reports: It fixes a security issue, but unless you're on a shared environment it's not a grave issue. It allows an application process to delete an arbitrary file, even a file it does not have permission to, but only during application startup (i.e. during evaluation of config.ru). Once the application is started, it cannot be exploited, so external visitors cannot influence this. If you deploy arbitrary untrusted apps on your server then this issue can be a problem. If all your apps are trusted (e.g. because your organization wrote them) then there's no problem. https://github.com/FooBarWidget/passenger/commit/8c6693e0818772c345c979840d28312c2edd4ba4#commitcomment-2643541
