CVE-2026-32893

Chamilo LMS has Reflected XSS via Unsanitized http_build_query() in Exercise Question List Pagination

Description

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.
