The SPIP jeux plugin versions prior to 4.1.1 contain a reflected cross-site scripting (XSS) vulnerability in the pre_propre pipeline. The plugin incorporates untrusted request parameters into HTML output without proper output encoding, allowing attackers to inject arbitrary script content into pages that render a jeux block.
