Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Semantic MediaWiki versions before 7.2.0 (Packagist mediawiki/semantic-media-wiki) have a reflected cross-site scripting flaw in Special:SearchByProperty, where the property and value parameters are echoed into page output and error messages without adequate encoding. The source does not say what an attacker must do to trigger it, such as whether a crafted link is needed, though reflected XSS typically requires a victim to open one. Upgrade to version 7.2.0 or later, which escapes the form value and derived error messages before rendering.
