Name of the Vulnerable Software and Affected Versions Gemirro versions prior to 0.16.0

Description The issue 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.

Recommendations For versions prior to 0.16.0, update to version 0.16.0 or later to resolve the issue. As a temporary workaround, consider restricting the upload of gems with crafted javascript: URLs in the homepage value of the ".gemspec" file to minimize the risk of exploitation. Avoid using the homepage value in the ".gemspec" file until the issue is resolved.
