Security readout for executives and security teams
CVE-2014-9478 is a cross-site scripting issue in MediaWiki's ExpandTemplates preview feature. It matters only when raw HTML is enabled, a risky configuration. An attacker could cause script or HTML to run through the Special:ExpandTemplates input path, potentially affecting users who view the preview. Exposure is likely limited to MediaWiki installations with ExpandTemplates available and $wgRawHTML set to true. Sites that never enabled raw HTML or do not expose Special:ExpandTemplates have lower apparent exposure, but administrators should confirm configuration rather than assume safety. Prioritize review for any public MediaWiki site that enabled raw HTML. The business risk is session theft, content manipulation, or user-targeted scripting, but available evidence does not support emergency treatment absent exposed vulnerable configuration. Mitigation focus: Apply the relevant MediaWiki security release or later supported version.; Disable $wgRawHTML unless there is a documented business need.; Restrict access to Special:ExpandTemplates if it is not required publicly..
