This medium-severity CVE scores 5.4 under NVD CVSS v3. EPSS exploit probability: 0.1%, top 96% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Chamilo LMS is a learning management system. Prior to 2.0.0-RC.3, a Reflected Cross-Site Scripting (XSS) vulnerability in the exercise question list admin panel allows an attacker to execute arbitrary JavaScript in an authenticated teacher's browser. The pagination code merges all $_GET parameters via array_merge() and outputs the result via http_build_query() directly into HTML href attributes without htmlspecialchars() encoding. This vulnerability is fixed in 2.0.0-RC.3.
