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.","published_at":"2023-07-29T07:12:18.290000Z","last_modified_at":null,"cvss_v3_score":8.8,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"none","ssvc_automatable":false,"ssvc_technical_impact":"total","cwes":["CWE-94"],"nvd_references":["https://nifi.apache.org/security.html#CVE-2023-36542","https://lists.apache.org/thread/swnly3dzhhq9zo3rofc8djq77stkhbof","http://seclists.org/fulldisclosure/2023/Jul/43","http://www.openwall.com/lists/oss-security/2023/07/29/1"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-29T01:33:40.240625Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"apache-software-foundation","vendor_name":"Apache Software Foundation","product_slug":"apache-nifi","product_name":"Apache NiFi","version_start":"0.0.2","version_start_inclusive":true,"version_end":"1.22.0","version_end_inclusive":true,"cpe23_uri":"cve5:apache-software-foundation:apache-nifi:0.0.2:1.22.0"}],"exploit_refs":[],"news":[],"references":[{"url":"https://nifi.apache.org/security.html#CVE-2023-36542","source_type":"MISC","tags":[]},{"url":"https://lists.apache.org/thread/swnly3dzhhq9zo3rofc8djq77stkhbof","source_type":"MAILING_LIST","tags":["mailing-list"]},{"url":"http://seclists.org/fulldisclosure/2023/Jul/43","source_type":"MAILING_LIST","tags":["mailing-list"]},{"url":"http://www.openwall.com/lists/oss-security/2023/07/29/1","source_type":"MAILING_LIST","tags":["mailing-list"]}],"timeline":[{"type":"published","at":"2023-07-29T07:12:18.290000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:29:00.783215Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:29:00.783215Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:29:00.783215Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T01:33:40.240625Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:33:40.240625Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:33:40.240625Z","label":"SSVC decision revised","source":"vulnrichment"}]}
