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-2016-7201 in the wild since at least 28 Mar 2022.\n\nAffected packages and fixed versions:\n- Microsoft.ChakraCore (NuGet): affected all versions; fixed in 1.2.2\n- Microsoft.ChakraCore (NuGet): affected all versions; fixed in 1.2.2\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-2016-7201/ (Markdown: https://insights.sbomify.com/CVE-2016-7201/index.md)","id":"CVE-2016-7201","markdown":"https://insights.sbomify.com/CVE-2016-7201/index.md","name":"CVE-2016-7201","record":{"aliases":["GHSA-4f5g-j7wg-7w8j"],"analysis":{"component_type":"browser","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Edge","requires_auth":"none","summary":"Remote attackers can execute arbitrary code or cause denial of service via a crafted website exploiting memory corruption in the Chakra engine.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"edge","vendor":"microsoft"}],"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-843","name":"Access of Resource Using Incompatible Type"}],"description":"The Chakra JavaScript scripting engine in Microsoft Edge allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, aka \"Scripting Engine Memory Corruption Vulnerability,\" a different vulnerability than CVE-2016-7200, CVE-2016-7202, CVE-2016-7203, CVE-2016-7208, CVE-2016-7240, CVE-2016-7242, and CVE-2016-7243.","ecosystems":["NuGet"],"exploits":{"exploitdb":2,"first_seen":"2016-11-18","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2016-11-18","kind":"exploitdb","ref":"40784","stars":null,"title":"Microsoft Edge - 'FillFromPrototypes' Type Confusion"},{"date":"2017-01-05","kind":"exploitdb","ref":"40990","stars":null,"title":"Microsoft Edge (Windows 10) - 'chakra.dll' Information Leak / Type Confusion Remote Code Execution"}],"tier":"exploited"},"has_fix":true,"headline":"Microsoft Edge Memory Corruption","id":"CVE-2016-7201","indexable":true,"kev":{"dateAdded":"2022-03-28","dueDate":"2022-04-18","knownRansomwareCampaignUse":"Unknown","product":"Edge","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Microsoft","vulnerabilityName":"Microsoft Edge Memory Corruption Vulnerability"},"kind":"cve","links":{"ecosystem":"NuGet","product":"microsoft:edge","products":["microsoft:edge"],"type":"memory_corruption","year":"2016"},"n_packages":2,"n_references":7,"next":{"headline":"ChakraCore RCE Vulnerability","id":"CVE-2016-7202"},"packages":[{"ecosystem":"NuGet","fixed":["1.2.2"],"introduced":["0"],"last_affected":[],"package":"Microsoft.ChakraCore","purl":null,"source":"GHSA-4f5g-j7wg-7w8j"},{"ecosystem":"NuGet","fixed":["1.2.2"],"introduced":["0"],"last_affected":[],"package":"Microsoft.ChakraCore","purl":"pkg:nuget/Microsoft.ChakraCore","source":"GHSA-4f5g-j7wg-7w8j"}],"prev":{"headline":"Microsoft Edge Memory Corruption","id":"CVE-2016-7200"},"products":["n/a"],"published":"2016-11-10","related":[{"cvss_score":8.8,"headline":"Microsoft Internet Explorer Memory Corruption","id":"CVE-2021-26411","kev_date_added":"2021-11-03","published":"2021-03-11"},{"cvss_score":8.8,"headline":"Microsoft Edge Memory Corruption","id":"CVE-2016-7200","kev_date_added":"2022-03-28","published":"2016-11-10"},{"cvss_score":8.1,"headline":"Microsoft Edge and Internet Explorer Type Confusion","id":"CVE-2017-0037","kev_date_added":"2022-03-28","published":"2017-02-26"},{"cvss_score":6.5,"headline":"Microsoft Internet Explorer and Edge Information Disclosure","id":"CVE-2016-3351","kev_date_added":"2022-05-24","published":"2016-09-14"},{"cvss_score":9.8,"headline":"Memory corruption in Microsoft ChakraCore","id":"CVE-2017-0028","kev_date_added":null,"published":"2017-07-14"},{"cvss_score":9.8,"headline":"ChakraCore RCE Vulnerability","id":"CVE-2017-0223","kev_date_added":null,"published":"2017-05-15"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code or cause denial of service via a crafted website exploiting memory corruption in the Chakra engine.","url":"https://insights.sbomify.com/CVE-2016-7201/"}
