The proposed properties override current configuration, enabling users with read access to invoke predefined verification methods with alternative settings. Apache NiFi installations that do not implement different levels of authorization for viewing and modifying component configuration are not subject to this vulnerability. Upgrading to Apache NiFi 2.10.0 is the recommended mitigation, requiring write access to submit configuration verification requests.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:L/VA:L/SC:L/SI:L/SA:L/AU:Y/R:U/V:C/RE:L/U:Amber","score":2.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","score":6.3},"cwes":["CWE-863"],"references":["https://lists.apache.org/thread/wrj3t4k2bwd2cztyp078f5kj3722qfzy","http://www.openwall.com/lists/oss-security/2026/06/20/4"],"products":["apache:nifi"],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-44911","score":0.00516,"percentile":0.43657,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-qvj8-gwpm-4x49","url":"https://osv.dev/vulnerability/GHSA-qvj8-gwpm-4x49","summary":"Apache NiFi allows read-only users to submit component configuration verification request","modified":"2026-09-11T22:25:58.855627915Z","packages":[{"ecosystem":"Maven","name":"org.apache.nifi:nifi-web-api","purl":"pkg:maven/org.apache.nifi/nifi-web-api","ranges":[">=1.15.0 <2.10.0"],"fixed":["2.10.0"]}]}],"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).
