LibreNMS is an open-source, PHP/MySQL/SNMP-based network monitoring system. Prior to 25.7.0, there is a reflected-XSS in report_this function in librenms/includes/functions.php. The report_this function had improper filtering (htmlentities function was incorrectly use in a href environment), which caused the project_issues parameter to trigger an XSS vulnerability. This vulnerability is fixed in 25.7.0.
