           Summary: Page titles in Special:Contributions are not HTML-
                    escaped
           Product: MediaWiki
           Version: unspecified
          Platform: All
               URL: http://en.wikipedia.org/w/index.php?title=Special:Contri
                    butions&dir=prev&limit=1&target=Amalthea%27%22%26lt
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: Normal
         Component: User interface
        AssignedTo: [email protected]
        ReportedBy: [email protected]


See the URL above. For testing purposes I created the account
»Amalthea'"&lt« and found that browsers "fixed" the broken html entity
"&amp;lt" and displayed a "<" instead - see the URL above. Apparently the
ampersand isn't escaped correctly on the contributions page,
Special:RecentPages didn't have that problem.

Fun could probably be had with some of the more disruptive entities. I don't
know if there's a HTML entity for the U+202E RIGHT-TO-LEFT OVERRIDE, but if so,
then &#x202e; this could be abused for some comedic effect.
