An attacker can craft a URL such as /api/v2/ilove.svg?love=<script>...</script>; when a victim navigates to it the injected script executes in the victim browser in the origin of the Netdata instance (reflected cross-site scripting). These endpoints are registered with HTTP_ACL_NOCHECK and anonymous access and, because bearer-token protection is disabled by default, are reachable without authentication on a default Netdata agent. The issue was resolved by removing the ilove endpoint.","epss":{"date":"2026-11-08","percentile":0.37461,"score":0.0043},"exploits":[],"kev":null,"metrics":[{"score":6.1,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},{"score":5.1,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","version":"4.0"}],"modifiedAt":1794146433067,"publishedAt":1783021062359,"references":[{"source":"CNA: VulnCheck","tags":["release-notes"],"url":"https://github.com/netdata/netdata/releases/tag/v2.3.1"},{"source":"CNA: VulnCheck","tags":["issue-tracking","patch"],"url":"https://github.com/netdata/netdata/pull/19919"},{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/netdata/netdata/commit/f82554fe9b21b5ae51a8663a3f4ddce84cac16af"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/netdata-reflected-cross-site-scripting-via-love-parameter-in-ilove-svg-endpoint"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
