  script_tag(name:"insight", value:"The following flaws exist:

  - ApiParse allows remote attackers to bypass intended per-title read restrictions via a parse action to api.php.
(CVE-2016-6331)

  - Remote attackers may obtain sensitive information by leveraging failure to terminate sessions when a user
account is blocked and when $wgBlockDisablesLogin is true. (CVE-2016-6332)

  - Cross-site scripting (XSS) vulnerability in the CSS user subpage preview feature allows remote attackers to
inject arbitrary web script or HTML via the edit box in Special:MyPage/common.css. (CVE-2016-6333)

  - Cross-site scripting (XSS) vulnerability in the Parser::replaceInternalLinks2 method allows remote attackers to
inject arbitrary web script or HTML via vectors involving replacement of percent encoding in unclosed internal
links. (CVE-2016-6334)

  - MediaWiki does not generate head items in the context of a given title, which allows remote attackers to obtain
sensitive information via a parse action to api.php. (CVE-2016-6335)

  - Remote authenticated users with undelete permissions may bypass intended suppressrevision and deleterevision
restrictions and remove the revision deletion status of arbitrary file revisions by using Special:Undelete.
(CVE-2016-6336)

  - Remote attackers may bypass intended session access restrictions by leveraging a call to the UserGetRights
function after Session::getAllowedUserRights. (CVE-2016-6337)");
