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-2021-31804 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-31804/ (Markdown: https://insights.sbomify.com/CVE-2021-31804/index.md)","id":"CVE-2021-31804","markdown":"https://insights.sbomify.com/CVE-2021-31804/index.md","name":"CVE-2021-31804","record":{"aliases":["DEBIAN-CVE-2021-31804","GHSA-636v-4www-6mj9","UBUNTU-CVE-2021-31804"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"LeoCAD 3D modeling","requires_auth":"none","summary":"A use-after-free vulnerability in LeoCAD allows attackers to execute arbitrary code or cause a crash when opening a new document.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"leocad","vendor":"leocad"}],"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-416","name":"Use After Free"}],"description":"LeoCAD before 21.03 sometimes allows a use-after-free during the opening of a new document.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Use after free in n/a","id":"CVE-2021-31804","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Forced OGNL evaluation, when evaluated on raw not validated user input in tag attributes, may lead to RCE.","id":"CVE-2021-31805"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-31803"},"products":["n/a"],"published":"2021-04-26","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2024-08-03","vendors":["n/a"]},"summary":"A use-after-free vulnerability in LeoCAD allows attackers to execute arbitrary code or cause a crash when opening a new document.","url":"https://insights.sbomify.com/CVE-2021-31804/"}
