No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2020-9493/ (Markdown: https://insights.sbomify.com/CVE-2020-9493/index.md)","id":"CVE-2020-9493","markdown":"https://insights.sbomify.com/CVE-2020-9493/index.md","name":"CVE-2020-9493","record":{"aliases":["CLSA-2026-1787931543","CLSA-2026-1790602996","CLSA-2026-1791960488","GHSA-prp9-9gxw-38j8"],"analysis":null,"analysis_generated_by":null,"assigner":"apache","cpe":[{"product":"chainsaw","vendor":"apache"},{"product":"log4j","vendor":"apache"},{"product":"reload4j","vendor":"qos"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","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-502","name":"Deserialization of Untrusted Data"}],"description":"A deserialization flaw was found in Apache Chainsaw versions prior to 2.1.0 which could lead to malicious code execution.","ecosystems":[],"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":"Java deserialization in Chainsaw","id":"CVE-2020-9493","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2020"},"n_packages":0,"n_references":4,"next":{"headline":"Denial of service in Apache Traffic Server","id":"CVE-2020-9494"},"packages":[],"prev":{"headline":"Improper Privilege Management in Apache Hadoop","id":"CVE-2020-9492"},"products":["Apache Chainsaw"],"published":"2021-06-16","related":[{"cvss_score":8.8,"headline":"A deserialization flaw in the Chainsaw component of Log4j 1 can lead to malicious code execution.","id":"CVE-2022-23307","kev_date_added":null,"published":"2022-01-18"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-07","vendors":["Apache Software Foundation"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2020-9493/"}
