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-2021-46463 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-2021-46463/ (Markdown: https://insights.sbomify.com/CVE-2021-46463/index.md)","id":"CVE-2021-46463","markdown":"https://insights.sbomify.com/CVE-2021-46463/index.md","name":"CVE-2021-46463","record":{"aliases":["ALPINE-CVE-2021-46463","CLEANSTART-2026-ML28121","GHSA-rcr4-6fgm-fjc6"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"NGINX njs module","requires_auth":"none","summary":"A type confusion vulnerability in the njs module allows attackers to hijack control flow, potentially leading to code execution or denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"njs","vendor":"f5"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-843","name":"Access of Resource Using Incompatible Type"}],"description":"njs through 0.7.1, used in NGINX, was discovered to contain a control flow hijack caused by a Type Confusion vulnerability in njs_promise_perform_then().","ecosystems":[],"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":"Memory corruption in n/a","id":"CVE-2021-46463","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-46474"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2021-46462"},"products":["n/a"],"published":"2022-02-14","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-19692","kev_date_added":null,"published":"2023-04-04"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-19695","kev_date_added":null,"published":"2023-04-04"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2022-43286","kev_date_added":null,"published":"2022-10-28"},{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2022-29379","kev_date_added":null,"published":"2022-05-25"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2022-27007","kev_date_added":null,"published":"2022-04-14"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2022-25139","kev_date_added":null,"published":"2022-02-14"}],"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":"A type confusion vulnerability in the njs module allows attackers to hijack control flow, potentially leading to code execution or denial of service.","url":"https://insights.sbomify.com/CVE-2021-46463/"}
