CVE-2026-27746
MEDIUMSPIP jeux < 4.1.1 - Reflected Cross-Site Scripting via pre_propre Pipeline
Title source: llmDescription
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. When a victim is induced to visit a crafted URL, the injected content is reflected into the response and executed in the victim's browser context.
