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-2018-3726 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- crud-file-server (npm): affected all versions; fixed in 0.8.0\n- crud-file-server (npm): affected all versions; fixed in 0.8.0\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-2018-3726/ (Markdown: https://insights.sbomify.com/CVE-2018-3726/index.md)","id":"CVE-2018-3726","markdown":"https://insights.sbomify.com/CVE-2018-3726/index.md","name":"CVE-2018-3726","record":{"aliases":["GHSA-h24f-9mm4-w336"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js file server","requires_auth":"none","summary":"An attacker can execute arbitrary scripts in the victim's browser via malicious file names in the crud-file-server Node.js module.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"crud-file-server","vendor":"crud-file-server_project"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"crud-file-server node module before 0.8.0 suffers from a Cross-Site Scripting vulnerability to a lack of validation of file names.","ecosystems":["npm"],"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":"Cross-site Scripting (XSS) - Stored in crud-file-server","id":"CVE-2018-3726","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2018"},"n_packages":2,"n_references":2,"next":{"headline":"Path Traversal in 626","id":"CVE-2018-3727"},"packages":[{"ecosystem":"npm","fixed":["0.8.0"],"introduced":["0"],"last_affected":[],"package":"crud-file-server","purl":null,"source":"GHSA-h24f-9mm4-w336"},{"ecosystem":"npm","fixed":["0.8.0"],"introduced":["0"],"last_affected":[],"package":"crud-file-server","purl":"pkg:npm/crud-file-server","source":"GHSA-h24f-9mm4-w336"}],"prev":{"headline":"Path Traversal in hekto","id":"CVE-2018-3725"},"products":["crud-file-server node module"],"published":"2018-06-07","related":[{"cvss_score":7.5,"headline":"Path Traversal in crud-file-server","id":"CVE-2018-3733","kev_date_added":null,"published":"2018-05-29"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["HackerOne"]},"summary":"An attacker can execute arbitrary scripts in the victim's browser via malicious file names in the crud-file-server Node.js module.","url":"https://insights.sbomify.com/CVE-2018-3726/"}
