An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-30858 and fix it if it is affected.\n\nWhat it is: CVE-2021-30858 is a high-severity use after free vulnerability in Apple Ipados, published on 24 Aug 2021. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: Yes. Attackers have exploited CVE-2021-30858 in the wild since at least 3 Nov 2021.\n\nAffected product: Apple Ipados. 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-2021-30858/ (Markdown: https://insights.sbomify.com/CVE-2021-30858/index.md)","id":"CVE-2021-30858","markdown":"https://insights.sbomify.com/CVE-2021-30858/index.md","name":"CVE-2021-30858","record":{"aliases":["DEBIAN-CVE-2021-30858","MGASA-2021-0447","RHSA-2021:4097","RHSA-2021:4686","RHSA-2022:0059","RHSA-2022:0075","RLSA-2021:4097","UBUNTU-CVE-2021-30858","USN-5087-1"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Apple iOS and macOS","requires_auth":"none","summary":"Attackers can execute arbitrary code via malicious web content due to a use-after-free flaw in Apple operating systems.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apple","cpe":[{"product":"ipados","vendor":"apple"},{"product":"iphone_os","vendor":"apple"},{"product":"macos","vendor":"apple"},{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/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":"A use after free issue was addressed with improved memory management.
