It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-85656 in the wild and no public exploit code.\n\nAffected product: Amazon log4j-cve-2021-44228-hotpatch. 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-2026-85656/ (Markdown: https://insights.sbomify.com/CVE-2026-85656/index.md)","id":"CVE-2026-85656","markdown":"https://insights.sbomify.com/CVE-2026-85656/index.md","name":"CVE-2026-85656","record":{"aliases":["GHSA-4p2r-rwww-hrf2"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Amazon Linux hotpatch","requires_auth":"low_privilege","summary":"A local attacker can execute arbitrary commands with root privileges by exploiting OS command injection in the Amazon Linux log4j hotpatch package.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMZN","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"An OS command injection issue in the log4j-cve-2021-44228-hotpatch package in Amazon Linux before 1.3-9 might allow a local user to execute arbitrary commands with root privileges via a Java process whose executable path contains embedded newline characters.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"OS command injection in Amazon log4j-cve-2021-44228-hotpatch","id":"CVE-2026-85656","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in Co-Authors, Multiple Authors and Guest Authors in an Author Box with PublishPress Authors","id":"CVE-2026-85657"},"packages":[],"prev":{"headline":"The Enable Media Replace plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.2.2.","id":"CVE-2026-85655"},"products":["log4j-cve-2021-44228-hotpatch"],"published":"2026-09-04","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-04","vendors":["Amazon"]},"summary":"A local attacker can execute arbitrary commands with root privileges by exploiting OS command injection in the Amazon Linux log4j hotpatch package.","url":"https://insights.sbomify.com/CVE-2026-85656/"}
