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-2020-8125 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- klona (npm): affected all versions; fixed in 1.1.1\n- klona (npm): affected all versions; fixed in 1.1.1\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-2020-8125/ (Markdown: https://insights.sbomify.com/CVE-2020-8125/index.md)","id":"CVE-2020-8125","markdown":"https://insights.sbomify.com/CVE-2020-8125/index.md","name":"CVE-2020-8125","record":{"aliases":["GHSA-8f89-2fwj-5v5r"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"npm klona library","requires_auth":"none","summary":"Prototype pollution in the klona npm library allows attackers to achieve remote code execution or cause denial of service in applications using the package.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"klona","vendor":"klona_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-20","name":"Improper Input Validation"}],"description":"Flaw in input validation in npm package klona version 1.1.0 and earlier may allow prototype pollution attack that may result in remote code execution or denial of service of applications using klona.","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":"Improper Input Validation in klona","id":"CVE-2020-8125","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"code_injection","year":"2020"},"n_packages":2,"n_references":1,"next":{"headline":"Command injection in EdgeSwitch","id":"CVE-2020-8126"},"packages":[{"ecosystem":"npm","fixed":["1.1.1"],"introduced":["0"],"last_affected":[],"package":"klona","purl":null,"source":"GHSA-8f89-2fwj-5v5r"},{"ecosystem":"npm","fixed":["1.1.1"],"introduced":["0"],"last_affected":[],"package":"klona","purl":"pkg:npm/klona","source":"GHSA-8f89-2fwj-5v5r"}],"prev":{"headline":"Improper Validation and Sanitization in url-parse","id":"CVE-2020-8124"},"products":["klona npm module"],"published":"2020-02-04","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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Prototype pollution in the klona npm library allows attackers to achieve remote code execution or cause denial of service in applications using the package.","url":"https://insights.sbomify.com/CVE-2020-8125/"}
