An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-46170 and fix it if it is affected.\n\nWhat it is: CVE-2021-46170 is a high-severity use after free vulnerability in Jerryscript Jerryscript, published on 14 Jan 2022. 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-2021-46170 in the wild and no public exploit code.\n\nAffected product: Jerryscript Jerryscript. 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-2021-46170/ (Markdown: https://insights.sbomify.com/CVE-2021-46170/index.md)","id":"CVE-2021-46170","markdown":"https://insights.sbomify.com/CVE-2021-46170/index.md","name":"CVE-2021-46170","record":{"aliases":["GHSA-q7gg-h9mq-mvc3","UBUNTU-CVE-2021-46170"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript engine","requires_auth":"none","summary":"A use-after-free vulnerability in the JerryScript JavaScript engine allows attackers to potentially execute arbitrary code or cause a denial of service.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"jerryscript","vendor":"jerryscript"}],"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":[{"id":"CWE-416","name":"Use After Free"}],"description":"An issue was discovered in JerryScript commit a6ab5e9.
