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-2021-38003 and fix it if it is affected.\n\nWhat it is: CVE-2021-38003 is a high-severity memory corruption vulnerability in Debian Debian Linux, published on 23 Nov 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-2021-38003 in the wild since at least 3 Nov 2021.\n\nAffected product: Debian Debian Linux. 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-2021-38003/ (Markdown: https://insights.sbomify.com/CVE-2021-38003/index.md)","id":"CVE-2021-38003","markdown":"https://insights.sbomify.com/CVE-2021-38003/index.md","name":"CVE-2021-38003","record":{"aliases":["DEBIAN-CVE-2021-38003","GHSA-4xx3-xg55-3wr5","UBUNTU-CVE-2021-38003"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Google Chrome","requires_auth":"none","summary":"A remote attacker can exploit heap corruption in the V8 engine via a crafted HTML page, potentially leading to code execution.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Chrome","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"chrome","vendor":"google"}],"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-755","name":"Improper Handling of Exceptional Conditions"}],"description":"Inappropriate implementation in V8 in Google Chrome prior to 95.0.4638.69 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2023-01-07","github_poc":2,"max_poc_stars":39,"metasploit":0,"nuclei":0,"refs":[{"date":"2023-01-07T06:09:14Z","kind":"github_poc","ref":"https://github.com/SpiralBL0CK/Chrome-V8-RCE-CVE-2021-38003","stars":39,"title":"CVE-2021-38003 exploits extracted from https://twitter.com/WhichbufferArda/status/1609604183535284224"},{"date":"2026-10-14T08:27:00Z","kind":"github_poc","ref":"https://github.com/jamezx32/CVE-2021-38003","stars":0,"title":"V8 TheHole leak via JSON.stringify - PoC + OrderedHashMap amplification"}],"tier":"exploited"},"has_fix":true,"headline":"Google Chromium V8 Memory Corruption","id":"CVE-2021-38003","indexable":true,"kev":{"dateAdded":"2021-11-03","dueDate":"2021-11-17","knownRansomwareCampaignUse":"Unknown","product":"Chromium V8","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Google","vulnerabilityName":"Google Chromium V8 Memory Corruption Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","fedoraproject:fedora","google:chrome"],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":4,"next":{"headline":"Information disclosure in Chrome","id":"CVE-2021-38004"},"packages":[],"prev":{"headline":"Use after free in Chrome","id":"CVE-2021-38002"},"products":["Chrome"],"published":"2021-11-23","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["Google"]},"summary":"A remote attacker can exploit heap corruption in the V8 engine via a crafted HTML page, potentially leading to code execution.","url":"https://insights.sbomify.com/CVE-2021-38003/"}
