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-2026-77907 in the wild and no public exploit code.\n\nAffected product: Microsoft Visual Studio 2026 version 18.9. 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-2026-77907/ (Markdown: https://insights.sbomify.com/CVE-2026-77907/index.md)","id":"CVE-2026-77907","markdown":"https://insights.sbomify.com/CVE-2026-77907/index.md","name":"CVE-2026-77907","record":{"aliases":["GHSA-47px-wrj6-fwj9"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Visual Studio IDE","requires_auth":"none","summary":"Heap-based buffer overflow in Visual Studio allows remote attackers to execute arbitrary code.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"visual_studio_2026","vendor":"microsoft"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"Heap-based buffer overflow in Visual Studio 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":"Visual Studio Remote Code Execution Vulnerability","id":"CVE-2026-77907","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Dynamics 365 On-Premises Remote Code Execution Vulnerability","id":"CVE-2026-77908"},"packages":[],"prev":{"headline":"Visual Studio Remote Code Execution Vulnerability","id":"CVE-2026-77906"},"products":["Microsoft Visual Studio 2026 version 18.9"],"published":"2026-09-08","related":[{"cvss_score":8.8,"headline":"Visual Studio Remote Code Execution Vulnerability","id":"CVE-2026-77906","kev_date_added":null,"published":"2026-09-08"}],"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":"2026-10-14","vendors":["Microsoft"]},"summary":"Heap-based buffer overflow in Visual Studio allows remote attackers to execute arbitrary code.","url":"https://insights.sbomify.com/CVE-2026-77907/"}
