{"id":"DEBIAN-CVE-2025-71385","details":"Netdata before 2.3.1 reflects the user-supplied love query parameter of the api/v2/ilove.svg and api/v3/ilove.svg endpoints verbatim into the generated SVG document (into a text element) without HTML or XML escaping, and serves the response with Content-Type image/svg+xml. An attacker can craft a URL such as /api/v2/ilove.svg?love=\u003cscript\u003e...\u003c/script\u003e; 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by removing the ilove endpoint.","modified":"2026-07-06T08:01:30.748161946Z","published":"2026-07-02T20:17:00.420Z","withdrawn":"2026-07-06T08:01:30.748161727Z","upstream":["CVE-2025-71385"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-71385"}],"affected":[{"package":{"name":"netdata","ecosystem":"Debian:11","purl":"pkg:deb/debian/netdata?arch=source&distro=bullseye"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.29.3-4","1.30.0-1","1.30.1-1","1.31.0-1","1.31.0-2","1.31.0-3","1.31.0-4","1.32.0-1","1.32.1-1","1.32.1-2","1.33.0-1","1.33.1-1","1.34.0-1","1.34.1-1","1.35.0-1","1.35.1-1","1.35.1-2","1.36.0-1","1.36.1-1","1.37.0-1","1.37.1-1","1.37.1-2","1.38.0-1","1.38.1-1","1.39.0-1","1.39.1-1","1.39.1-2","1.40.0-1","1.40.0-2","1.40.1-1","1.41.0-1","1.42.0-1","1.42.1-1","1.42.2-1","1.42.3-1","1.42.4-1","1.43.0-1","1.43.1-1","1.43.2-1","1.44.3-1","1.44.3-2","1.46.3-1","1.46.3-2","1.47.0-1","1.47.1-1","1.47.2-1","1.47.5-1","2.0.3+dfsg-1","2.0.3+dfsg-2","2.0.3+dfsg-3","2.0.3+dfsg-4","2.0.3+dfsg-5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-71385.json"}},{"package":{"name":"netdata","ecosystem":"Debian:12","purl":"pkg:deb/debian/netdata?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.37.1-2","1.38.0-1","1.38.1-1","1.39.0-1","1.39.1-1","1.39.1-2","1.40.0-1","1.40.0-2","1.40.1-1","1.41.0-1","1.42.0-1","1.42.1-1","1.42.2-1","1.42.3-1","1.42.4-1","1.43.0-1","1.43.1-1","1.43.2-1","1.44.3-1","1.44.3-2","1.46.3-1","1.46.3-2","1.47.0-1","1.47.1-1","1.47.2-1","1.47.5-1","2.0.3+dfsg-1","2.0.3+dfsg-2","2.0.3+dfsg-3","2.0.3+dfsg-4","2.0.3+dfsg-5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-71385.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
