Hello Josh, Steve, vendors,

   an cross-site scripting (XSS) flaw was found in the way cgit, a fast
web interface for Git, displayed the file name in the rename hint. A
remote attacker could provide a specially-crafted web page, which once
visited by an authenticated Cgit user, with push access to the
repository, would lead to arbitrary web script or HTML code execution.

I think you are a tad off, here. The vulnerability I discovered actually
is only exploitable *by* a user with push access as it requires to push
a commit that renames any file to a file with a malicious file name.

Have updated issue description in:
https://bugzilla.redhat.com/show_bug.cgi?id=725042#c0

Hoping of it to sound better now.

Thanks again && Regards, Jan.

The description (and the categorization of the vulnerability, which
definitely is a low severity one if it counts as a vulnerability at all)
should be corrected to reflect that.

Could you allocate a CVE id for this?

Thank you&&  Regards, Jan.
