{"id":"CVE-2020-36862","state":"PUBLISHED","title":"Nagios XI < 5.6.11 Unauthenticated XSS and SSRF via Highcharts","description":"Nagios XI versions prior to 5.6.11 contain unauthenticated vulnerabilities in the Highcharts local exporting tool. Crafted export requests could (1) inject script into exported/returned content due to insufficient output encoding (XSS), and (2) cause the server to fetch attacker-specified URLs (SSRF), potentially accessing internal network resources. An unauthenticated remote attacker can leverage these issues to execute script in a user's browser when the exported content is viewed and to disclose sensitive information reachable from the export server via SSRF.","publishedAt":"2025-10-30T21:46:37.314Z","updatedAt":"2025-11-17T18:21:40.292Z","severity":{"score":6.9,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:L/SI:L/SA:L","source":"VulnCheck"},"assigner":"VulnCheck","products":["Nagios XI"],"affected":[{"vendor":"Nagios","product":"XI","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"5.6.11","versionType":"semver"}],"modules":["Highcharts local exporting tool / export server (render service & parameter handlers)"]}],"references":["https://www.nagios.com/changelog/nagios-xi/","https://www.vulncheck.com/advisories/nagios-xi-unauthenticated-xss-and-ssrf-via-highcharts"],"weaknesses":["CWE-79","CWE-918"],"ingestedAt":"2026-10-29T19:47:24.909Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2020/36xxx/CVE-2020-36862.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2020-36862","state":"PUBLISHED","datePublished":"2025-10-30T21:46:37.314Z","dateUpdated":"2025-11-17T18:21:40.292Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2025-10-30T13:06:15.570Z"},"containers":{"cna":{"title":"Nagios XI < 5.6.11 Unauthenticated XSS and SSRF via Highcharts","descriptions":[{"lang":"en","value":"Nagios XI versions prior to 5.6.11 contain unauthenticated vulnerabilities in the Highcharts local exporting tool.
