  script_tag(name:"insight", value:"Multiple flaws exist due to:

  - a Cross-site scripting (XSS) vulnerability that allows remote attackers to inject arbitrary web script or HTML via a File: link to a nonexistent image.

  - multiple cross-site scripting (XSS) vulnerabilities, when unspecified JavaScript gadgets are used, allow remote attackers
  to inject arbitrary web script or HTML via the userlang parameter to w/index.php.

  - MediaWiki not sending a restrictive X-Frame-Options HTTP header, which allows remote attackers to conduct clickjacking attacks via an embedded API response in an IFRAME element.

  - MediaWiki allowing remote attackers to bypass GlobalBlocking extension IP address blocking and thus creating an account via unspecified vectors.

  - MediaWiki not properly protecting user block metadata, which allows remote administrators to read a user block reason via a reblock attempt.");
