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-2021-41783 in the wild and no public exploit code.\n\nAffected product: Foxit Pdf Editor. 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-2021-41783/ (Markdown: https://insights.sbomify.com/CVE-2021-41783/index.md)","id":"CVE-2021-41783","markdown":"https://insights.sbomify.com/CVE-2021-41783/index.md","name":"CVE-2021-41783","record":{"aliases":["GHSA-f5q3-g3jg-vwqg"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"PDF reader/editor","requires_auth":"none","summary":"Attackers can execute arbitrary code via a use-after-free vulnerability in Foxit PDF products caused by mishandled JavaScript.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"pdf_editor","vendor":"foxit"},{"product":"pdf_reader","vendor":"foxit"},{"product":"phantompdf","vendor":"foxit"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Foxit PDF Reader before 11.1 and PDF Editor before 11.1, and PhantomPDF before 10.1.6, allow attackers to trigger a use-after-free and execute arbitrary code because JavaScript is mishandled.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Use after free in n/a","id":"CVE-2021-41783","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"foxit:pdf_editor","products":["foxit:pdf_editor","foxit:pdf_reader"],"type":"use_after_free","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Use after free in n/a","id":"CVE-2021-41784"},"packages":[],"prev":{"headline":"Use after free in n/a","id":"CVE-2021-41782"},"products":["n/a"],"published":"2022-08-29","related":[{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2022-28104","kev_date_added":null,"published":"2022-05-20"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2022-24954","kev_date_added":null,"published":"2022-02-11"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2022-24955","kev_date_added":null,"published":"2022-02-11"},{"cvss_score":8.8,"headline":"Foxit PDF Editor/Reader Updater Privilege Escalation","id":"CVE-2026-91798","kev_date_added":null,"published":"2026-09-23"},{"cvss_score":8.8,"headline":"Foxit PDF Editor installer local privilege escalation","id":"CVE-2026-91800","kev_date_added":null,"published":"2026-09-23"},{"cvss_score":8.8,"headline":"Security Vulnerability Report – Foxit PDF Editor/Reader Updater DLL Search Path Hijacking","id":"CVE-2026-91803","kev_date_added":null,"published":"2026-09-23"},{"cvss_score":8.8,"headline":"Foxit PDF Editor/Reader FoxitUpdater Race Condition Local Privilege Escalation Vulnerability","id":"CVE-2026-91813","kev_date_added":null,"published":"2026-09-23"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code via a use-after-free vulnerability in Foxit PDF products caused by mishandled JavaScript.","url":"https://insights.sbomify.com/CVE-2021-41783/"}
