{"id":"CVE-2025-71385","summary":"Netdata \u003c 2.3.1 - Reflected Cross-Site Scripting via love Parameter in ilove.svg Endpoint","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":"2026-07-09T04:00:44.936246633Z","published":"2026-07-02T19:37:42.359Z","database_specific":{"cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71385.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71385.json"},{"type":"ADVISORY","url":"https://github.com/netdata/netdata/releases/tag/v2.3.1"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-71385"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/netdata-reflected-cross-site-scripting-via-love-parameter-in-ilove-svg-endpoint"},{"type":"REPORT","url":"https://github.com/netdata/netdata/pull/19919"},{"type":"FIX","url":"https://github.com/netdata/netdata/commit/f82554fe9b21b5ae51a8663a3f4ddce84cac16af"},{"type":"PACKAGE","url":"https://github.com/netdata/netdata"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/netdata/netdata","events":[{"introduced":"0"},{"fixed":"3417b1eeda82e77e3873de7ff15925b10c9f59e0"},{"fixed":"f82554fe9b21b5ae51a8663a3f4ddce84cac16af"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"2.3.1"}],"cpe":"cpe:2.3:a:netdata:netdata:*:*:*:*:*:*:*:*"}}],"versions":["v2.3.0","v2.2.0","v2.1.0","v2.0.0","v1.47.0","v1.99.0","v1.46.0","v1.45.0","v1.44.0","v1.43.0","v1.42.0","v1.41.0","v1.40.0","v1.39.0","v1.38.0","v1.37.0","v1.36.0","v1.35.0","v1.34.0","1.34.0","v1.33.1","v1.33.0","v1.32.1","1.32.1","v1.32.0","v1.31.0","v1.30.1","v1.30.0","v1.29.3","v1.29.2","v1.29.1","v1.29.0","v1.27.0_0104103941","v1.28.0","v1.27.0","v1.26.0","v1.25.0","v1.24.0","v1.23.2","v1.23.1_infiniband","v1.23.1","v1.23.0","v1.22.1","v1.22.0","v1.21.1","v1.21.0","v1.20.0","v1.19.0","v1.18.1","v1.18.0","v1.17.1","v1.17.0","v1.16.1","v1.16.0","v1.15.0","v1.14.0","v1.14.0-rc0","v1.13.0","v1.12.2","v1.12.1","v1.12.0","v1.12.0-rc3","v1.12.0-rc2","v1.12.0-rc1","v1.12.0-rc0","v1.11.1","v1.11.0","v1.10.0","untagged-10d59b9e5fa68b9500e1","v1.9.0","v1.8.0","v1.7.0","v1.6.0","v1.5.0","v1.4.0","v1.3.0","v1.2.0","v1.1.0","v1.0.0","v1.0rc","v0.2","v0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-71385.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"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"}]}
