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-2022-31306 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-2022-31306/ (Markdown: https://insights.sbomify.com/CVE-2022-31306/index.md)","id":"CVE-2022-31306","markdown":"https://insights.sbomify.com/CVE-2022-31306/index.md","name":"CVE-2022-31306","record":{"aliases":["GHSA-6wgc-59vm-vww8"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Nginx NJS library","requires_auth":"none","summary":"A use-after-free vulnerability in the Nginx NJS library allows attackers to cause a segmentation violation and denial of service.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"njs","vendor":"f5"}],"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":"Nginx NJS v0.7.2 was discovered to contain a segmentation violation in the function njs_array_convert_to_slow_array at src/njs_array.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":false,"headline":"Use after free in n/a","id":"CVE-2022-31306","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2022"},"n_packages":0,"n_references":2,"next":{"headline":"Use after free in n/a","id":"CVE-2022-31307"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2022-31303"},"products":["n/a"],"published":"2022-06-21","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":"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 the Nginx NJS library allows attackers to cause a segmentation violation and denial of service.","url":"https://insights.sbomify.com/CVE-2022-31306/"}
