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-2026-96238 in the wild and no public exploit code.\n\nAffected product: Microsoft .NET 10.0 runtime. 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-2026-96238/ (Markdown: https://insights.sbomify.com/CVE-2026-96238/index.md)","id":"CVE-2026-96238","markdown":"https://insights.sbomify.com/CVE-2026-96238/index.md","name":"CVE-2026-96238","record":{"aliases":["UBUNTU-CVE-2026-96238"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":".NET Framework","requires_auth":"none","summary":"An origin validation error in .NET allows attackers to bypass security features over the network, requiring patches for affected versions.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-346","name":"Origin Validation Error"}],"description":"Origin validation error in .NET allows an unauthorized attacker to bypass a security feature 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":true,"headline":".NET Security Feature Bypass Vulnerability","id":"CVE-2026-96238","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Windows WalletService Elevation of Privilege Vulnerability","id":"CVE-2026-96243"},"packages":[],"prev":{"headline":".NET Remote Code Execution Vulnerability","id":"CVE-2026-96237"},"products":[".NET 10.0 runtime",".NET 11.0 runtime",".NET 8.0 runtime",".NET 9.0 runtime","Microsoft Visual Studio 2022 version 17.14","Microsoft Visual Studio 2026 version 18.10"],"published":"2026-10-13","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-10-29","vendors":["Microsoft"]},"summary":"An origin validation error in .NET allows attackers to bypass security features over the network, requiring patches for affected versions.","url":"https://insights.sbomify.com/CVE-2026-96238/"}
