An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-16490 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mpath (npm): affected all versions; fixed in 0.5.1\n- mpath (npm): affected all versions; fixed in 0.5.1\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-2018-16490/ (Markdown: https://insights.sbomify.com/CVE-2018-16490/index.md)","id":"CVE-2018-16490","markdown":"https://insights.sbomify.com/CVE-2018-16490/index.md","name":"CVE-2018-16490","record":{"aliases":["GHSA-h466-j336-74wx"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js mpath library","requires_auth":"none","summary":"Attackers can inject arbitrary properties into Object.prototype via prototype pollution in the mpath library, potentially leading to code execution or denial of service.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"mpath","vendor":"mpath_project"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"A prototype pollution vulnerability was found in module mpath \u003c0.5.1 that allows an attacker to inject arbitrary properties onto Object.prototype.","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":"Prototype Pollution in mpath","id":"CVE-2018-16490","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"code_injection","year":"2018"},"n_packages":2,"n_references":1,"next":{"headline":"Prototype Pollution in node.extend","id":"CVE-2018-16491"},"packages":[{"ecosystem":"npm","fixed":["0.5.1"],"introduced":["0"],"last_affected":[],"package":"mpath","purl":null,"source":"GHSA-h466-j336-74wx"},{"ecosystem":"npm","fixed":["0.5.1"],"introduced":["0"],"last_affected":[],"package":"mpath","purl":"pkg:npm/mpath","source":"GHSA-h466-j336-74wx"}],"prev":{"headline":"Prototype Pollution in just-extend","id":"CVE-2018-16489"},"products":["mpath"],"published":"2019-02-01","related":[{"cvss_score":5.6,"headline":"Prototype Pollution","id":"CVE-2021-23438","kev_date_added":null,"published":"2021-09-01"}],"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":"2024-08-05","vendors":["HackerOne"]},"summary":"Attackers can inject arbitrary properties into Object.prototype via prototype pollution in the mpath library, potentially leading to code execution or denial of service.","url":"https://insights.sbomify.com/CVE-2018-16490/"}
