The resolution introduces a new Required Permission for referencing remote resources, restricting configuration of these components to privileged users. The permission prevents unprivileged users from configuring Processors and Controller Services annotated with the new Reference Remote Resources restriction. Upgrading to Apache NiFi 1.23.0 is the recommended mitigation.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-94"],"references":["http://seclists.org/fulldisclosure/2023/Jul/43","http://www.openwall.com/lists/oss-security/2023/07/29/1","https://lists.apache.org/thread/swnly3dzhhq9zo3rofc8djq77stkhbof","https://nifi.apache.org/security.html#CVE-2023-36542","http://seclists.org/fulldisclosure/2023/Jul/43"],"products":["apache:nifi"],"source":"nvd","synced_at":"2026-10-19T21:38:35.729974749+00:00"},"epss":{"cve":"CVE-2023-36542","score":0.01903,"percentile":0.79702,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-r969-8v3h-23v9","url":"https://osv.dev/vulnerability/GHSA-r969-8v3h-23v9","summary":"Apache NiFi Code Injection vulnerability","modified":"2025-09-15T07:42:01.270014Z","packages":[{"ecosystem":"Maven","name":"org.apache.nifi:nifi-cdc-mysql-bundle","purl":"pkg:maven/org.apache.nifi/nifi-cdc-mysql-bundle","ranges":[">=0.0.2 <1.23.0"],"fixed":["1.23.0"]},{"ecosystem":"Maven","name":"org.apache.nifi:nifi-jms-processors","purl":"pkg:maven/org.apache.nifi/nifi-jms-processors","ranges":[">=0.0.2 <1.23.0"],"fixed":["1.23.0"]},{"ecosystem":"Maven","name":"org.apache.nifi:nifi-standard-processors","purl":"pkg:maven/org.apache.nifi/nifi-standard-processors","ranges":[">=0.0.2 <1.23.0"],"fixed":["1.23.0"]},{"ecosystem":"Maven","name":"org.apache.nifi:nifi-dbcp-service","purl":"pkg:maven/org.apache.nifi/nifi-dbcp-service","ranges":[">=0.0.2 <1.23.0"],"fixed":["1.23.0"]},{"ecosystem":"Maven","name":"org.apache.nifi:nifi-hikari-dbcp-service","purl":"pkg:maven/org.apache.nifi/nifi-hikari-dbcp-service","ranges":[">=0.0.2 <1.23.0"],"fixed":["1.23.0"]},{"ecosystem":"Maven","name":"org.apache.nifi:nifi-hadoop-dbcp-service","purl":"pkg:maven/org.apache.nifi/nifi-hadoop-dbcp-service","ranges":[">=0.0.2 <1.23.0"],"fixed":["1.23.0"]},{"ecosystem":"Maven","name":"org.apache.nifi:nifi-hbase_2-client-service","purl":"pkg:maven/org.apache.nifi/nifi-hbase_2-client-service","ranges":[">=0.0.2 <1.23.0"],"fixed":["1.23.0"]},{"ecosystem":"Maven","name":"org.apache.nifi:nifi-record-serialization-services","purl":"pkg:maven/org.apache.nifi/nifi-record-serialization-services","ranges":[">=0.0.2 <1.23.0"],"fixed":["1.23.0"]}]}],"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).
