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-2021-46462 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-2021-46462/ (Markdown: https://insights.sbomify.com/CVE-2021-46462/index.md)","id":"CVE-2021-46462","markdown":"https://insights.sbomify.com/CVE-2021-46462/index.md","name":"CVE-2021-46462","record":{"aliases":["ALPINE-CVE-2021-46462","CLEANSTART-2026-ML08252","GHSA-ghww-grw3-m7r6"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"NGINX JavaScript library","requires_auth":"none","summary":"A segmentation violation in the njs library allows attackers to cause a denial of service via crafted input.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"njs","vendor":"f5"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"njs through 0.7.1, used in NGINX, was discovered to contain a segmentation violation via njs_object_set_prototype in /src/njs_object.c.","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":"Null dereference in n/a","id":"CVE-2021-46462","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-46463"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2021-46461"},"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":"Memory corruption in n/a","id":"CVE-2021-46463","kev_date_added":null,"published":"2022-02-14"},{"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":"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 segmentation violation in the njs library allows attackers to cause a denial of service via crafted input.","url":"https://insights.sbomify.com/CVE-2021-46462/"}
