An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-17195 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.nifi:nifi (Maven): affected from 1.0.0; fixed in 1.8.0\n- org.apache.nifi:nifi (Maven): affected from 1.0.0; fixed in 1.8.0\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-2018-17195/ (Markdown: https://insights.sbomify.com/CVE-2018-17195/index.md)","id":"CVE-2018-17195","markdown":"https://insights.sbomify.com/CVE-2018-17195/index.md","name":"CVE-2018-17195","record":{"aliases":["GHSA-3jq8-jg75-rqv6"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache NiFi","requires_auth":"none","summary":"An attacker can perform CSRF attacks on the template upload API via MiTM, potentially injecting malicious code or modifying data.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"nifi","vendor":"apache"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-319","name":"Cleartext Transmission of Sensitive Information"}],"description":"The template upload API endpoint accepted requests from different domain when sent in conjunction with ARP spoofing + man in the middle (MiTM) attack, resulting in a CSRF attack.
