It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2016-4434 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.tika:tika-core (Maven): affected all versions; fixed in 1.13\n- org.apache.tika:tika-core (Maven): affected all versions; fixed in 1.13\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-2016-4434/ (Markdown: https://insights.sbomify.com/CVE-2016-4434/index.md)","id":"CVE-2016-4434","markdown":"https://insights.sbomify.com/CVE-2016-4434/index.md","name":"CVE-2016-4434","record":{"aliases":["DEBIAN-CVE-2016-4434","GHSA-4xr4-4c65-hj7f","UBUNTU-CVE-2016-4434"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Apache Tika library","requires_auth":"none","summary":"Remote attackers can exploit XML External Entity vulnerabilities in Apache Tika to read sensitive files or cause denial of service via crafted documents.","user_interaction":"required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"tika","vendor":"apache"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"Apache Tika before 1.13 does not properly initialize the XML parser or choose handlers, which might allow remote attackers to conduct XML External Entity (XXE) attacks via vectors involving (1) spreadsheets in OOXML files and (2) XMP metadata in PDF and other file formats, a related issue to CVE-2016-2175.","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":"Apache Tika does not properly initialize the XML parser or choose handlers","id":"CVE-2016-4434","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xxe","year":"2016"},"n_packages":2,"n_references":6,"next":{"headline":"Missing authorization in Cloud Foundry","id":"CVE-2016-4435"},"packages":[{"ecosystem":"Maven","fixed":["1.13"],"introduced":["0"],"last_affected":[],"package":"org.apache.tika:tika-core","purl":null,"source":"GHSA-4xr4-4c65-hj7f"},{"ecosystem":"Maven","fixed":["1.13"],"introduced":["0"],"last_affected":[],"package":"org.apache.tika:tika-core","purl":"pkg:maven/org.apache.tika/tika-core","source":"GHSA-4xr4-4c65-hj7f"}],"prev":{"headline":"Apache Struts Open Redirect","id":"CVE-2016-4433"},"products":["n/a"],"published":"2017-09-29","related":[{"cvss_score":8.8,"headline":"Allocation of Resources Without Limits or Throttling in Apache Tika","id":"CVE-2019-10088","kev_date_added":null,"published":"2019-08-02"},{"cvss_score":8.4,"headline":"Apache Tika has XXE vulnerability","id":"CVE-2025-66516","kev_date_added":null,"published":"2025-12-04"},{"cvss_score":8.4,"headline":"Apache Tika PDF parser module: XXE vulnerability in PDFParser's handling of XFA","id":"CVE-2025-54988","kev_date_added":null,"published":"2025-08-20"},{"cvss_score":8.1,"headline":"Command injection in org.apache.tika:tika-core","id":"CVE-2018-1335","kev_date_added":null,"published":"2018-04-25"},{"cvss_score":7.8,"headline":"Allocation of Resources Without Limits or Throttling in Apache Tika","id":"CVE-2019-10094","kev_date_added":null,"published":"2019-08-02"},{"cvss_score":7.5,"headline":"Apache Tika is vulnerable to entity expansions which can lead to a denial of service attack","id":"CVE-2018-11796","kev_date_added":null,"published":"2018-10-09"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can exploit XML External Entity vulnerabilities in Apache Tika to read sensitive files or cause denial of service via crafted documents.","url":"https://insights.sbomify.com/CVE-2016-4434/"}
