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-2020-1951 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.tika:tika (Maven): affected from 1.0; fixed in 1.24\n- org.apache.tika:tika (Maven): affected from 1.0; fixed in 1.24\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-2020-1951/ (Markdown: https://insights.sbomify.com/CVE-2020-1951/index.md)","id":"CVE-2020-1951","markdown":"https://insights.sbomify.com/CVE-2020-1951/index.md","name":"CVE-2020-1951","record":{"aliases":["DEBIAN-CVE-2020-1951","GHSA-3264-3fm9-fg44","UBUNTU-CVE-2020-1951"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Java document parser","requires_auth":"none","summary":"Attackers can cause a denial of service via infinite loop in Apache Tika by submitting crafted PSD files.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"tika","vendor":"apache"},{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"business_process_management_suite","vendor":"oracle"},{"product":"communications_messaging_server","vendor":"oracle"},{"product":"flexcube_private_banking","vendor":"oracle"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"}],"description":"A carefully crafted or corrupt PSD file can cause an infinite loop in Apache Tika's PSDParser in versions 1.0-1.23.","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":"Infinite Loop in Apache Tika","id":"CVE-2020-1951","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux","debian:debian_linux","oracle:flexcube_private_banking"],"type":"denial_of_service","year":"2020"},"n_packages":2,"n_references":5,"next":{"headline":"Improper Certificate Validation in Apache IoTDB","id":"CVE-2020-1952"},"packages":[{"ecosystem":"Maven","fixed":["1.24"],"introduced":["1.0"],"last_affected":[],"package":"org.apache.tika:tika","purl":null,"source":"GHSA-3264-3fm9-fg44"},{"ecosystem":"Maven","fixed":["1.24"],"introduced":["1.0"],"last_affected":[],"package":"org.apache.tika:tika","purl":"pkg:maven/org.apache.tika/tika","source":"GHSA-3264-3fm9-fg44"}],"prev":{"headline":"Uncontrolled Resource Consumption in Apache Tika","id":"CVE-2020-1950"},"products":["Apache Tika"],"published":"2020-03-23","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":7.8,"headline":"Apache Tika does not properly initialize the XML parser or choose handlers","id":"CVE-2016-4434","kev_date_added":null,"published":"2017-09-29"},{"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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can cause a denial of service via infinite loop in Apache Tika by submitting crafted PSD files.","url":"https://insights.sbomify.com/CVE-2020-1951/"}
