{"id":"CVE-2026-29519","state":"PUBLISHED","title":"Lucee CFML Server Reflected XSS via URL Path Parsing","description":"Lucee CFML Server versions across the 5.3.x, 6.1.x, 6.2.x, and 7.0.x release lines contain a reflected cross-site scripting vulnerability in URL path parsing that allows unauthenticated remote attackers to execute arbitrary JavaScript in a victim's browser by embedding HTML or JavaScript payloads within the request path. Attackers can craft a malicious URL containing injected script content that is reflected in the server's response without proper output encoding, enabling session hijacking or unauthorized actions against the Lucee administrative interface when a victim visits the crafted link.","publishedAt":"2026-07-10T14:09:24.237Z","updatedAt":"2026-07-14T18:39:56.709Z","severity":{"score":6.2,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:H/SI:L/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["lucee Lucee"],"affected":[{"vendor":"lucee","product":"Lucee","packageURL":"pkg:github/lucee/Lucee","defaultStatus":"affected","versions":[{"version":"5.3.1.95","status":"affected","lessThanOrEqual":"7.0.0.395","versionType":"custom"}],"repo":"https://github.com/lucee/Lucee"}],"references":["https://github.com/L4V4D0/CVE-2026-29519-Lucee-Reflected-XSS","https://www.vulncheck.com/advisories/lucee-cfml-server-reflected-xss-via-url-path-parsing"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:31.369Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/29xxx/CVE-2026-29519.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-29519","state":"PUBLISHED","datePublished":"2026-07-10T14:09:24.237Z","dateUpdated":"2026-07-14T18:39:56.709Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-03-04T15:39:26.872Z"},"containers":{"cna":{"title":"Lucee CFML Server Reflected XSS via URL Path Parsing","descriptions":[{"lang":"en","value":"Lucee CFML Server versions across the 5.3.x, 6.1.x, 6.2.x, and 7.0.x release lines contain a reflected cross-site scripting vulnerability in URL path parsing that allows unauthenticated remote attackers to execute arbitrary JavaScript in a victim's browser by embedding HTML or JavaScript payloads within the request path.
