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-2026-72970 and fix it if it is affected.\n\nWhat it is: CVE-2026-72970 is a high-severity memory corruption vulnerability in Microsoft Edge Chromium, published on 14 Aug 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-72970 in the wild and no public exploit code.\n\nAffected product: Microsoft Edge Chromium. 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-2026-72970/ (Markdown: https://insights.sbomify.com/CVE-2026-72970/index.md)","id":"CVE-2026-72970","markdown":"https://insights.sbomify.com/CVE-2026-72970/index.md","name":"CVE-2026-72970","record":{"aliases":["GHSA-rmf3-9hmx-hc46"],"analysis":{"component_type":"browser","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Edge browser","requires_auth":"none","summary":"Heap-based buffer overflow in Microsoft Edge allows remote attackers to execute arbitrary code over the network.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"edge_chromium","vendor":"microsoft"}],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:L/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"Heap-based buffer overflow in Microsoft Edge (Chromium-based) allows an unauthorized attacker to execute code over a network.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Microsoft Edge (Chromium-based) Remote Code Execution Vulnerability","id":"CVE-2026-72970","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:edge_chromium","products":["microsoft:edge_chromium"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Windows Container Isolation FS Filter Driver (unionfs.sys) Tampering Vulnerability","id":"CVE-2026-72971"},"packages":[],"prev":{"headline":"Windows Program Compatibility Assistant Service Elevation of Privilege Vulnerability","id":"CVE-2026-72969"},"products":["Microsoft Edge (Chromium-based)"],"published":"2026-08-14","related":[{"cvss_score":9.6,"headline":"Microsoft Edge (Chromium-based) Elevation of Privilege Vulnerability","id":"CVE-2024-21326","kev_date_added":null,"published":"2024-01-26"},{"cvss_score":9.6,"headline":"Microsoft Edge (Chromium-based) Elevation of Privilege Vulnerability","id":"CVE-2023-35618","kev_date_added":null,"published":"2023-12-07"},{"cvss_score":9.6,"headline":"Microsoft Edge (Chromium-based) Elevation of Privilege Vulnerability","id":"CVE-2023-36735","kev_date_added":null,"published":"2023-09-15"},{"cvss_score":9.6,"headline":"Microsoft Edge (Chromium-based) Security Feature Bypass Vulnerability","id":"CVE-2022-33649","kev_date_added":null,"published":"2022-08-09"},{"cvss_score":9,"headline":"Microsoft Edge (Chromium-based) Remote Code Execution Vulnerability","id":"CVE-2026-58289","kev_date_added":null,"published":"2026-07-03"},{"cvss_score":8.8,"headline":"Microsoft Edge (Chromium-based) Remote Code Execution Vulnerability","id":"CVE-2026-69486","kev_date_added":null,"published":"2026-09-15"},{"cvss_score":8.8,"headline":"Microsoft Edge (Chromium-based) Elevation of Privilege Vulnerability","id":"CVE-2026-85893","kev_date_added":null,"published":"2026-09-15"}],"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)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-28","vendors":["Microsoft"]},"summary":"Heap-based buffer overflow in Microsoft Edge allows remote attackers to execute arbitrary code over the network.","url":"https://insights.sbomify.com/CVE-2026-72970/"}
