The attack involves unsanitized HTTP parameters being output in a form page, allowing attackers to leak cookies and other sensitive information from ca/uhn/fhir/to/BaseController.java via a specially crafted URL. (This module is not generally used in production systems so the attack surface is expected to be low, but affected systems are recommended to upgrade immediately.)","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://github.com/jamesagnew/hapi-fhir/commit/8f41159eb147eeb964cad68b28eff97acac6ea9a","https://github.com/jamesagnew/hapi-fhir/issues/1335","https://github.com/jamesagnew/hapi-fhir/releases/tag/v3.8.0","https://github.com/jamesagnew/hapi-fhir/commit/8f41159eb147eeb964cad68b28eff97acac6ea9a","https://github.com/jamesagnew/hapi-fhir/issues/1335"],"products":["fhir:hapi_fhir"],"source":"nvd","synced_at":"2026-10-19T20:57:00.690689396+00:00"},"epss":{"cve":"CVE-2019-12741","score":0.01268,"percentile":0.6978,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-52mh-p2m2-w625","url":"https://osv.dev/vulnerability/GHSA-52mh-p2m2-w625","summary":"Cross-site Scripting in HAPI FHIR","modified":"2023-11-08T04:01:06.066835Z","packages":[{"ecosystem":"Maven","name":"ca.uhn.hapi.fhir:hapi-fhir-base","purl":"pkg:maven/ca.uhn.hapi.fhir/hapi-fhir-base","ranges":["<3.8.0"],"fixed":["3.8.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
