Details

As written in the advisory (Markdown source, shown as plain text).

### Summary Reflected-XSS in `report_this` function in `librenms/includes/functions.php` ### Details Recently, it was discovered that the `report_this` function had improper filtering (`htmlentities` function was incorrectly used in a href environment), which caused the `project_issues` parameter to trigger an XSS vulnerability. The Vulnerable Sink: https://github.com/librenms/librenms/blob/master/includes/functions.php#L444 ### PoC GET `project_issues=javascript:alert(document.cookie)` ### Impact XSS vulnerabilities allow attackers to execute malicious scripts in users' browsers, enabling unauthorized access to sensitive data, session hijacking, or malware distribution. ### Suggestion It is recommended to filter dangerous protocols, e.g. `javascript:`/`file:`.
