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-2026-69522 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- Microsoft.DiaSymReader.Native (NuGet): affected from 17.10.0-beta1.24272.1; fixed in 18.9.0-beta1.26405.2\n- Microsoft.DiaSymReader.Native (NuGet): affected from 17.10.0-beta1.24272.1; fixed in 18.9.0-beta1.26405.2\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-2026-69522/ (Markdown: https://insights.sbomify.com/CVE-2026-69522/index.md)","id":"CVE-2026-69522","markdown":"https://insights.sbomify.com/CVE-2026-69522/index.md","name":"CVE-2026-69522","record":{"aliases":["BELL-CVE-2026-69522","GHSA-2j8r-3c22-8565","UBUNTU-CVE-2026-69522"],"analysis":{"component_type":"developer_tool","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 over the network.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[],"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":["NuGet"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":".NET and Visual Studio Remote Code Execution Vulnerability","id":"CVE-2026-69522","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Windows Active Directory Domain Services Remote Code Execution Vulnerability","id":"CVE-2026-69524"},"packages":[{"ecosystem":"NuGet","fixed":["18.9.0-beta1.26405.2"],"introduced":["17.10.0-beta1.24272.1"],"last_affected":[],"package":"Microsoft.DiaSymReader.Native","purl":null,"source":"GHSA-2j8r-3c22-8565"},{"ecosystem":"NuGet","fixed":["18.9.0-beta1.26405.2"],"introduced":["17.10.0-beta1.24272.1"],"last_affected":[],"package":"Microsoft.DiaSymReader.Native","purl":"pkg:nuget/Microsoft.DiaSymReader.Native","source":"GHSA-2j8r-3c22-8565"}],"prev":{"headline":"Windows iSCSI Remote Code Execution Vulnerability","id":"CVE-2026-69521"},"products":[".NET 10.0",".NET 11.0",".NET 8.0",".NET 9.0","Microsoft .NET Framework 3.5 AND 4.6.2/4.7/4.7.1/4.7.2","Microsoft .NET Framework 3.5 AND 4.7.2","Microsoft .NET Framework 3.5 AND 4.8","Microsoft .NET Framework 3.5 AND 4.8.1","Microsoft .NET Framework 4.6.2/4.7/4.7.1/4.7.2","Microsoft .NET Framework 4.8","Microsoft .NET Framework 4.8.1","Microsoft Visual Studio 2022 version 17.14","Microsoft Visual Studio 2026 version 18.9"],"published":"2026-09-08","related":[],"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":"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":"2026-10-26","vendors":["Microsoft"]},"summary":"Heap-based buffer overflow in Visual Studio allows remote attackers to execute arbitrary code over the network.","url":"https://insights.sbomify.com/CVE-2026-69522/"}
