An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-16040 exists.\n\nAffected product: Google Chrome. 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-2020-16040/ (Markdown: https://insights.sbomify.com/CVE-2020-16040/index.md)","id":"CVE-2020-16040","markdown":"https://insights.sbomify.com/CVE-2020-16040/index.md","name":"CVE-2020-16040","record":{"aliases":["DEBIAN-CVE-2020-16040","GHSA-6v42-384q-wwf5","UBUNTU-CVE-2020-16040"],"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":"Remote attackers can exploit heap corruption in V8 via crafted HTML pages, potentially executing arbitrary code in Google Chrome.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Chrome","cpe":[{"product":"chrome","vendor":"google"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-20","name":"Improper Input Validation"},{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"Insufficient data validation in V8 in Google Chrome prior to 87.0.4280.88 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2020-11-19","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2020-11-19","kind":"metasploit","ref":"exploit/multi/browser/chrome_simplifiedlowering_overflow","stars":null,"title":"Google Chrome versions before 87.0.4280.88 integer overflow during SimplfiedLowering phase"},{"date":"2021-04-06","kind":"exploitdb","ref":"49745","stars":null,"title":"Google Chrome 86.0.4240 V8 - Remote Code Execution"}],"tier":"weaponised"},"has_fix":true,"headline":"Memory corruption in Chrome","id":"CVE-2020-16040","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"google:chrome","products":["google:chrome"],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":5,"next":{"headline":"Information disclosure in Chrome","id":"CVE-2020-16041"},"packages":[],"prev":{"headline":"Use after free in Chrome","id":"CVE-2020-16039"},"products":["Chrome"],"published":"2021-01-08","related":[{"cvss_score":9.6,"headline":"Google Chromium GPU Heap Buffer Overflow","id":"CVE-2022-4135","kev_date_added":"2022-11-28","published":"2022-11-25"},{"cvss_score":9.6,"headline":"Google Chrome Use-After-Free","id":"CVE-2020-16017","kev_date_added":"2021-11-03","published":"2021-01-08"},{"cvss_score":9.6,"headline":"Google Chrome for Android UI Heap Buffer Overflow","id":"CVE-2020-16010","kev_date_added":"2021-11-03","published":"2020-11-03"},{"cvss_score":8.8,"headline":"Google Chromium V8 Out of Bounds Write","id":"CVE-2026-87491","kev_date_added":"2026-09-09","published":"2026-09-09"},{"cvss_score":8.8,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2026-85046","kev_date_added":"2026-09-04","published":"2026-09-03"},{"cvss_score":8.8,"headline":"Google Chromium V8 Out-of-Bounds Read and Write","id":"CVE-2026-11645","kev_date_added":"2026-06-09","published":"2026-06-08"},{"cvss_score":8.8,"headline":"Google Dawn Use-After-Free","id":"CVE-2026-5281","kev_date_added":"2026-04-01","published":"2026-04-01"}],"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)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["Google"]},"summary":"Remote attackers can exploit heap corruption in V8 via crafted HTML pages, potentially executing arbitrary code in Google Chrome.","url":"https://insights.sbomify.com/CVE-2020-16040/"}
