Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-26850 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.nifi:nifi-single-user-utils (Maven): affected all versions; fixed in 1.16\n- org.apache.nifi:nifi-single-user-utils (Maven): affected all versions; fixed in 1.16\n- nifi (Bitnami): affected from 1.14.0; fixed in 1.16.0\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-2022-26850/ (Markdown: https://insights.sbomify.com/CVE-2022-26850/index.md)","id":"CVE-2022-26850","markdown":"https://insights.sbomify.com/CVE-2022-26850/index.md","name":"CVE-2022-26850","record":{"aliases":["BIT-nifi-2022-26850","GHSA-rvp4-r3g6-8hxq"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache NiFi","requires_auth":"low_privilege","summary":"An attacker with local access could read sensitive credentials from a temporary file during configuration updates in Apache NiFi.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"nifi","vendor":"apache"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-668","name":"Exposure of Resource to Wrong Sphere"}],"description":"When creating or updating credentials for single-user access, Apache NiFi wrote a copy of the Login Identity Providers configuration to the operating system temporary directory.
