Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-86089 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nifi (Bitnami): affected from 2.11.0; fixed in 2.12.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-86089/ (Markdown: https://insights.sbomify.com/CVE-2026-86089/index.md)","id":"CVE-2026-86089","markdown":"https://insights.sbomify.com/CVE-2026-86089/index.md","name":"CVE-2026-86089","record":{"aliases":["BIT-nifi-2026-86089","GHSA-5rjq-rw3w-qr4c","MINI-r6f5-p3m4-62vm"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache NiFi","requires_auth":"low_privilege","summary":"Authenticated users can bypass Process Group authorization to enumerate or migrate flows without proper access rights in Apache NiFi.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"nifi","vendor":"apache"}],"cvss":{"score":2.3,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/S:P/AU:Y/R:U/V:C/RE:L/U:Clear","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Apache NiFi 2.11.0 supports migrating the contents of a version-controlled Process Group into a Connector using REST API methods that list eligible migration sources and submit migration requests. The framework authorized both methods against the target Connector alone, without evaluating access to the Process Groups involved. The absence of Process Group authorization allowed an authenticated user with read access to a Connector to enumerate the identifiers, names, and flow registry details of version-controlled Process Groups outside the scope of granted read policies. It also allowed a user with write access to a Connector to migrate a Process Group without write access to that Process Group, copying the flow definition, referenced assets, and component state into the Connector, and leaving the source Process Group disabled and renamed. Migration excludes sensitive property values and requires the source Process Group to be stopped with empty queues, which limits the scope of exposure. Apache NiFi installations that do not implement component-level authorization policies for Process Groups are not subject to this vulnerability, because the framework enforces Connector write permissions as the security boundary. Upgrading to Apache NiFi 2.12.0 is the recommended mitigation, which filters migration sources to Process Groups the requesting user is authorized to read, and requires write access to the source Process Group when submitting a migration request.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Apache NiFi: Missing Process Group Authorization for Connector Migration","id":"CVE-2026-86089","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"apache:nifi","products":["apache:nifi"],"type":"missing_authorization","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"ntopng before 6.7.260717 Missing Authorization on the Notification Endpoint and Recipient Delete Handlers","id":"CVE-2026-86090"},"packages":[{"ecosystem":"Bitnami","fixed":["2.12.0"],"introduced":["2.11.0"],"last_affected":[],"package":"nifi","purl":"pkg:bitnami/nifi","source":"BIT-nifi-2026-86089"}],"prev":{"headline":"IBM® Db2® could allow an authenticated user to send a specially crafted request to write arbitrary files on the system","id":"CVE-2026-86087"},"products":["Apache NiFi"],"published":"2026-09-16","related":[{"cvss_score":9.8,"headline":"Improper Restriction of XML External Entity Reference in Apache NiFi","id":"CVE-2018-1309","kev_date_added":null,"published":"2018-05-23"},{"cvss_score":9.8,"headline":"Apache NiFi XSS issue in context path handling","id":"CVE-2017-15697","kev_date_added":null,"published":"2018-01-23"},{"cvss_score":9.8,"headline":"Injection in Apache NiFi","id":"CVE-2017-5636","kev_date_added":null,"published":"2017-10-19"},{"cvss_score":8.8,"headline":"Apache NiFi: Uncontrolled Resource Consumption through Decompression of HTTP Requests","id":"CVE-2026-68981","kev_date_added":null,"published":"2026-08-03"},{"cvss_score":8.8,"headline":"Apache NiFi: Potential Code Injection with Properties Referencing Remote Resources","id":"CVE-2023-36542","kev_date_added":null,"published":"2023-07-29"},{"cvss_score":8.8,"headline":"Apache NiFi: Potential Code Injection with Database Services using H2","id":"CVE-2023-34468","kev_date_added":null,"published":"2023-06-12"},{"cvss_score":8.8,"headline":"Improper Neutralization of Command Elements in Shell User Group Provider","id":"CVE-2022-33140","kev_date_added":null,"published":"2022-06-15"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-17","vendors":["Apache Software Foundation"]},"summary":"Authenticated users can bypass Process Group authorization to enumerate or migrate flows without proper access rights in Apache NiFi.","url":"https://insights.sbomify.com/CVE-2026-86089/"}
