It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-50649 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- dotnet (Bitnami): affected from 8.0.0; fixed in 8.0.29, 9.0.18\n- dotnet-sdk (Bitnami): affected from 8.0.0; fixed in 8.0.29, 9.0.18\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-2026-50649/ (Markdown: https://insights.sbomify.com/CVE-2026-50649/index.md)","id":"CVE-2026-50649","markdown":"https://insights.sbomify.com/CVE-2026-50649/index.md","name":"CVE-2026-50649","record":{"aliases":["BIT-dotnet-2026-50649","BIT-dotnet-sdk-2026-50649","MINI-28wj-p962-gp8m","MINI-fxv5-9wfj-ccr5","UBUNTU-CVE-2026-50649"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":".NET runtime","requires_auth":"none","summary":"An attacker can execute arbitrary code locally by exploiting unsafe deserialization in the .NET runtime.","user_interaction":"required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":".net","vendor":"microsoft"},{"product":".net_framework","vendor":"microsoft"},{"product":"visual_studio_2026","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/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-502","name":"Deserialization of Untrusted Data"}],"description":"Deserialization of untrusted data in .NET allows an unauthorized attacker to execute code locally.","ecosystems":["Bitnami"],"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 Remote Code Execution Vulnerability","id":"CVE-2026-50649","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"microsoft:.net","products":["microsoft:.net","microsoft:.net_framework"],"type":"deserialization","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":".NET Framework Elevation of Privilege Vulnerability","id":"CVE-2026-50650"},"packages":[{"ecosystem":"Bitnami","fixed":["8.0.29","9.0.18"],"introduced":["8.0.0","9.0.0"],"last_affected":[],"package":"dotnet","purl":"pkg:bitnami/dotnet","source":"BIT-dotnet-2026-50649"},{"ecosystem":"Bitnami","fixed":["8.0.29","9.0.18"],"introduced":["8.0.0","9.0.0"],"last_affected":[],"package":"dotnet-sdk","purl":"pkg:bitnami/dotnet-sdk","source":"BIT-dotnet-sdk-2026-50649"}],"prev":{"headline":".NET Framework Denial of Service Vulnerability","id":"CVE-2026-50648"},"products":[".NET 8.0 runtime",".NET 9.0 runtime","Microsoft .NET Framework 3.5","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 2026 version 18.7"],"published":"2026-07-14","related":[{"cvss_score":9.8,"headline":".NET and Visual Studio Remote Code Execution Vulnerability","id":"CVE-2024-43498","kev_date_added":null,"published":"2024-11-12"},{"cvss_score":9.1,"headline":"NET, .NET Framework, and Visual Studio Security Feature Bypass Vulnerability","id":"CVE-2024-0057","kev_date_added":null,"published":"2024-01-09"},{"cvss_score":8.8,"headline":".NET Security Feature Bypass Vulnerability","id":"CVE-2026-96957","kev_date_added":null,"published":"2026-10-13"},{"cvss_score":8.8,"headline":".NET and Visual Studio Elevation of Privilege Vulnerability","id":"CVE-2026-69439","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":8.8,"headline":".NET and Visual Studio Remote Code Execution Vulnerability","id":"CVE-2026-71328","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":8.8,"headline":"ASP.NET Core Elevation of Privilege Vulnerability","id":"CVE-2026-47300","kev_date_added":null,"published":"2026-07-14"},{"cvss_score":8.8,"headline":"ASP.NET Core Elevation of Privilege Vulnerability","id":"CVE-2026-47303","kev_date_added":null,"published":"2026-07-14"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"An attacker can execute arbitrary code locally by exploiting unsafe deserialization in the .NET runtime.","url":"https://insights.sbomify.com/CVE-2026-50649/"}
