{"cve":"CVE-2026-25903","nvd":{"published":"2026-02-17T10:15:57.950","modified":"2026-06-17T10:25:24.670","status":"Analyzed","description":"Apache NiFi 1.1.0 through 2.7.2 are missing authorization when updating configuration properties on extension components that have specific Required Permissions based on the Restricted annotation. The Restricted annotation indicates additional privileges required to add the annotated component to the flow configuration, but framework authorization did not check restricted status when updating a component previously added. The missing authorization requires a more privileged user to add a restricted component to the flow configuration, but permits a less privileged user to make property configuration changes. Apache NiFi installations that do not implement different levels of authorization for Restricted components are not subject to this vulnerability because the framework enforces write permissions as the security boundary. Upgrading to Apache NiFi 2.8.0 is the recommended mitigation.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:A/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/S:P/AU:Y/R:I/V:C/RE:M/U:Amber","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H","score":6.6},"cwes":["CWE-862"],"references":["https://lists.apache.org/thread/jf6bkt9sk6xvshy8xyxv3vtlxd340345","http://www.openwall.com/lists/oss-security/2026/02/16/1"],"products":["apache:nifi"],"source":"nvd","synced_at":"2026-10-19T22:23:35.260773158+00:00"},"epss":{"cve":"CVE-2026-25903","score":0.00752,"percentile":0.5503,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-c5w7-m8wf-xc77","url":"https://osv.dev/vulnerability/GHSA-c5w7-m8wf-xc77","summary":"Apache NiFi: Missing Authorization of Restricted Permissions for Component Updates","modified":"2026-02-20T09:26:10.935834Z","packages":[{"ecosystem":"Maven","name":"org.apache.nifi:nifi-web-api","purl":"pkg:maven/org.apache.nifi/nifi-web-api","ranges":[">=1.1.0 <2.8.0"],"fixed":["2.8.0"]}]}],"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).
