Name of the Vulnerable Software and Affected Versions SemanticMediaWiki versions 2.5.0 through 7.3.0

Description A stored cross-site scripting issue exists where users with page-edit rights can inject scripts via Code-typed property values. An attacker can embed HTML markup within a valid JSON value, which the CodeStringValueFormatter function renders without escaping on the 'Special:Browse' endpoint, leading to JavaScript execution in the sessions of users who view the page.

Recommendations Update SemanticMediaWiki to version 7.3.1 or later.
