Description Andrej Nemec 2016-05-09 06:57:52 UTC

An XSS vulnerability was found in ikiwiki. The instance in cgierror() is a potential cross-site scripting attack, because an attacker could conceivably cause some module to raise an exception that includes attacker-supplied HTML in its message, for example via a crafted filename.

Upstream fix:
