An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-97801 in the wild and no public exploit code.\n\nAffected product: Microsoft .NET Framework 3.5. 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-2026-97801/ (Markdown: https://insights.sbomify.com/CVE-2026-97801/index.md)","id":"CVE-2026-97801","markdown":"https://insights.sbomify.com/CVE-2026-97801/index.md","name":"CVE-2026-97801","record":{"aliases":["GHSA-pjfw-qhmc-7gc7"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":".NET Framework","requires_auth":"none","summary":"An unauthorized attacker can tamper with data over the network due to improper input validation in the .NET Framework.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-1287","name":"Improper Validation of Specified Type of Input"}],"description":"Improper validation of specified type of input in .NET Framework allows an unauthorized attacker to perform tampering 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":".NET Framework Tampering Vulnerability","id":"CVE-2026-97801","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Windows Kernel Elevation of Privilege Vulnerability","id":"CVE-2026-97803"},"packages":[],"prev":{"headline":"Windows Mobile Broadband Elevation of Privilege Vulnerability","id":"CVE-2026-97800"},"products":["Microsoft .NET Framework 3.5","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"],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-29","vendors":["Microsoft"]},"summary":"An unauthorized attacker can tamper with data over the network due to improper input validation in the .NET Framework.","url":"https://insights.sbomify.com/CVE-2026-97801/"}
