An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2018-9206 exists.\n\nAffected packages and fixed versions:\n- blueimp-file-upload (npm): affected all versions; fixed in 9.22.1\n- blueimp-file-upload (npm): affected all versions; fixed in 9.22.1\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-2018-9206/ (Markdown: https://insights.sbomify.com/CVE-2018-9206/index.md)","id":"CVE-2018-9206","markdown":"https://insights.sbomify.com/CVE-2018-9206/index.md","name":"CVE-2018-9206","record":{"aliases":["CVE-2025-63994","DEBIAN-CVE-2018-9206","GHSA-4cj8-g9cp-v5wr","UBUNTU-CVE-2018-9206"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"jQuery File Upload","requires_auth":"none","summary":"Unauthenticated attackers can upload arbitrary files to execute code on systems using the vulnerable jQuery File Upload library.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"larry_cashdollar","cpe":[{"product":"jquery_file_upload","vendor":"jquery_file_upload_project"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"Unauthenticated arbitrary file upload vulnerability in Blueimp jQuery-File-Upload \u003c= v9.22.0","ecosystems":["npm"],"exploits":{"exploitdb":4,"first_seen":"2018-10-09","github_poc":6,"max_poc_stars":63,"metasploit":1,"nuclei":1,"refs":[{"date":"2018-10-24T20:24:20Z","kind":"github_poc","ref":"https://github.com/Stahlz/JQShell","stars":63,"title":"A weaponized version of CVE-2018-9206"},{"date":"2018-10-22T16:33:22Z","kind":"github_poc","ref":"https://github.com/Den1al/CVE-2018-9206","stars":13,"title":"A Python PoC for CVE-2018-9206"},{"date":"2025-12-27T02:31:22Z","kind":"github_poc","ref":"https://github.com/flame-11/CVE-2018-9206-jquery-file-upload","stars":1,"title":null},{"date":"2018-10-09","kind":"metasploit","ref":"exploit/unix/webapp/jquery_file_upload","stars":null,"title":"blueimp's jQuery (Arbitrary) File Upload"},{"date":"2018-10-11","kind":"exploitdb","ref":"45584","stars":null,"title":"jQuery-File-Upload 9.22.0 - Arbitrary File Upload"},{"date":"2018-11-06","kind":"exploitdb","ref":"45790","stars":null,"title":"blueimp's jQuery 9.22.0 - (Arbitrary) File Upload (Metasploit)"},{"date":"2018-11-06","kind":"exploitdb","ref":"45790","stars":null,"title":"blueimp's jQuery 9.22.0 - (Arbitrary) File Upload (Metasploit)"},{"date":"2019-01-11T22:23:06Z","kind":"github_poc","ref":"https://github.com/cved-sources/cve-2018-9206","stars":0,"title":"cve-2018-9206"}],"tier":"weaponised"},"has_fix":true,"headline":"Unrestricted Upload of File with Dangerous Type in blueimp-file-upload","id":"CVE-2018-9206","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"file_upload","year":"2018"},"n_packages":2,"n_references":7,"next":{"headline":"Unrestricted Upload of File with Dangerous Type in jquery-file-upload","id":"CVE-2018-9207"},"packages":[{"ecosystem":"npm","fixed":["9.22.1"],"introduced":["0"],"last_affected":[],"package":"blueimp-file-upload","purl":null,"source":"GHSA-4cj8-g9cp-v5wr"},{"ecosystem":"npm","fixed":["9.22.1"],"introduced":["0"],"last_affected":[],"package":"blueimp-file-upload","purl":"pkg:npm/blueimp-file-upload","source":"GHSA-4cj8-g9cp-v5wr"}],"prev":{"headline":"Path traversal in avatar uploader","id":"CVE-2018-9205"},"products":["Blueimp jQuery-File-Upload"],"published":"2018-10-11","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-12","vendors":["Blueimp"]},"summary":"Unauthenticated attackers can upload arbitrary files to execute code on systems using the vulnerable jQuery File Upload library.","url":"https://insights.sbomify.com/CVE-2018-9206/"}
