Description Vincent Danen 2014-06-03 14:33:59 UTC
New versions of MediaWiki have been announced [1] to fix the following flaw [2]:

XSS vulnerability in MediaWiki before 1.22.7, due to usernames on
Special:PasswordReset being parsed as wikitext.  The username on
Special:PasswordReset can be supplied by anyone and will be parsed with
wgRawHtml enabled.  Since Special:PasswordReset is whitelisted by default on
private wikis, this could potentially lead to an XSS crossing a privilege

This is corrected [3] in upstream versions 1.19.16, 1.21.10, and 1.22.7.  A CVE has been requested [4].
