What is CVE-2026-27746?

The SPIP Jeux Plugin prior to version 4.1.1 exposes web applications to reflected cross-site scripting attacks. By improperly handling untrusted request parameters in the pre_propre pipeline, the plugin allows attackers to create specially crafted URLs. When victims click on these URLs, harmful scripts are injected into the responses, enabling the execution of arbitrary scripts within the user's browser context. This vulnerability poses a significant risk, potentially compromising user data and security.
