Stored cross-site scripting (XSS) vulnerability in Gemirro before 0.16.0 allows attackers to inject arbitrary web script via a crafted javascript: URL in the "homepage" value of a ".gemspec" file.

This can be used to build a gem for upload to the Gemirro server, in order to achieve stored XSS via the author name hyperlink.
