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-2021-39239 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.jena:jena-core (Maven): affected all versions; fixed in 4.2.0\n- org.apache.jena:jena-core (Maven): affected all versions; fixed in 4.2.0\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-2021-39239/ (Markdown: https://insights.sbomify.com/CVE-2021-39239/index.md)","id":"CVE-2021-39239","markdown":"https://insights.sbomify.com/CVE-2021-39239/index.md","name":"CVE-2021-39239","record":{"aliases":["DEBIAN-CVE-2021-39239","GHSA-7rp6-w7mg-h8rw","UBUNTU-CVE-2021-39239"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Java semantic web library","requires_auth":"none","summary":"An attacker can exploit XML processing flaws in Apache Jena to read local files and send them to a remote server.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"jena","vendor":"apache"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"A vulnerability in XML processing in Apache Jena, in versions up to 4.1.0, may allow an attacker to execute XML External Entities (XXE), including exposing the contents of local files to a remote server.","ecosystems":["Maven"],"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":"XML External Entity (XXE) vulnerability","id":"CVE-2021-39239","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xxe","year":"2021"},"n_packages":2,"n_references":4,"next":{"headline":"Other in n/a","id":"CVE-2021-39240"},"packages":[{"ecosystem":"Maven","fixed":["4.2.0"],"introduced":["0"],"last_affected":[],"package":"org.apache.jena:jena-core","purl":null,"source":"GHSA-7rp6-w7mg-h8rw"},{"ecosystem":"Maven","fixed":["4.2.0"],"introduced":["0"],"last_affected":[],"package":"org.apache.jena:jena-core","purl":"pkg:maven/org.apache.jena/jena-core","source":"GHSA-7rp6-w7mg-h8rw"}],"prev":{"headline":"Memory corruption in HP Enterprise LaserJet; HP LaserJet Managed; HP Enterprise PageWide; HP PageWide Managed printers","id":"CVE-2021-39238"},"products":["Apache Jena"],"published":"2021-09-16","related":[{"cvss_score":9.8,"headline":"Processing external DTDs","id":"CVE-2022-28890","kev_date_added":null,"published":"2022-05-05"},{"cvss_score":8.8,"headline":"Apache Jena: Configuration files uploaded by administrative users are not check properly","id":"CVE-2025-50151","kev_date_added":null,"published":"2025-07-21"},{"cvss_score":8.8,"headline":"Apache Jena: Exposure of execution in script engine expressions.","id":"CVE-2023-32200","kev_date_added":null,"published":"2023-07-12"},{"cvss_score":7.5,"headline":"Apache Jena: Administrative users can create files outside the server directory space via the admin UI","id":"CVE-2025-49656","kev_date_added":null,"published":"2025-07-21"},{"cvss_score":5.4,"headline":"Apache Jena: Exposure of arbitrary execution in script engine expressions.","id":"CVE-2023-22665","kev_date_added":null,"published":"2023-04-25"}],"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":["Apache Software Foundation"]},"summary":"An attacker can exploit XML processing flaws in Apache Jena to read local files and send them to a remote server.","url":"https://insights.sbomify.com/CVE-2021-39239/"}
