CVE-2026-27746: Spip Jeux

Medium severity, CVSS 6.1. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Spip Jeux: before 4.1.1 (fixed in 4.1.1)
