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-2026-28672 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.ranger:ranger (Maven): affected from 0.6.0 up to 2.8.0; no fix listed\n- org.apache.ranger:ranger (Maven): affected from 0.6.0 up to 2.8.0; no fix listed\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-2026-28672/ (Markdown: https://insights.sbomify.com/CVE-2026-28672/index.md)","id":"CVE-2026-28672","markdown":"https://insights.sbomify.com/CVE-2026-28672/index.md","name":"CVE-2026-28672","record":{"aliases":["GHSA-6qc3-v8fv-fv9j"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Ranger","requires_auth":"none","summary":"Attackers can execute arbitrary OS commands via crafted usernames in Apache Ranger, requiring an upgrade to mitigate.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"ranger","vendor":"apache"}],"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-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability in Apache Ranger.\n\nThis issue affects Apache Ranger: from 0.6 through 2.8.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":"2026-08-24","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-08-24T16:29:12Z","kind":"github_poc","ref":"https://github.com/oscerd/CVE-2026-28672","stars":0,"title":"Reproducer for CVE-2026-28672 (Apache Ranger UnixUserGroupBuilder OS command injection via username in the unixusersync module)"}],"tier":"poc_unverified"},"has_fix":false,"headline":"Apache Ranger: OS Command Injection via Username in UnixUserGroupBuilder","id":"CVE-2026-28672","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"xiaoheiFS Vulnerable to RCE via Unrestricted Plugin Installation (Manifest Manipulation)","id":"CVE-2026-28673"},"packages":[{"ecosystem":"Maven","fixed":[],"introduced":["0.6.0"],"last_affected":["2.8.0"],"package":"org.apache.ranger:ranger","purl":null,"source":"GHSA-6qc3-v8fv-fv9j"},{"ecosystem":"Maven","fixed":[],"introduced":["0.6.0"],"last_affected":["2.8.0"],"package":"org.apache.ranger:ranger","purl":"pkg:maven/org.apache.ranger/ranger","source":"GHSA-6qc3-v8fv-fv9j"}],"prev":{"headline":"Race condition in Android","id":"CVE-2026-28671"},"products":["Apache Ranger"],"published":"2026-08-10","related":[{"cvss_score":9.8,"headline":"Apache Ranger: SQL Injection vulnerability in lookup functionality","id":"CVE-2026-32227","kev_date_added":null,"published":"2026-08-10"},{"cvss_score":9.8,"headline":"Apache Ranger: Privilege Escalation via URL Parameter","id":"CVE-2026-40920","kev_date_added":null,"published":"2026-08-10"},{"cvss_score":9.8,"headline":"Apache Ranger: Remote Code Execution via JDBC URL Injection","id":"CVE-2026-42537","kev_date_added":null,"published":"2026-08-10"},{"cvss_score":9.8,"headline":"Apache Ranger: Remote Code Execution via Arbitrary Class Instantiation","id":"CVE-2026-44416","kev_date_added":null,"published":"2026-08-10"},{"cvss_score":9.8,"headline":"Apache Ranger: Remote Code Execution Vulnerability in GraalScriptEngineCreator","id":"CVE-2026-55799","kev_date_added":null,"published":"2026-08-10"},{"cvss_score":9.8,"headline":"Apache Ranger: Remote Code Execution Vulnerability in NashornScriptEngineCreator","id":"CVE-2025-59059","kev_date_added":null,"published":"2026-03-03"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-12","vendors":["Apache Software Foundation"]},"summary":"Attackers can execute arbitrary OS commands via crafted usernames in Apache Ranger, requiring an upgrade to mitigate.","url":"https://insights.sbomify.com/CVE-2026-28672/"}
