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-2026-47304 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- System.Security.Cryptography.Xml (NuGet): affected from 10.0.0; fixed in 10.0.10\n- System.Security.Cryptography.Xml (NuGet): affected from 10.0.0; fixed in 10.0.10\n- System.Security.Cryptography.Xml (NuGet): affected from 8.0.0; fixed in 8.0.4\n- System.Security.Cryptography.Xml (NuGet): affected from 8.0.0; fixed in 8.0.4\n- System.Security.Cryptography.Xml (NuGet): affected from 9.0.0; fixed in 9.0.18\n- System.Security.Cryptography.Xml (NuGet): affected from 9.0.0; fixed in 9.0.18\n- dotnet (Bitnami): affected from 8.0.0; fixed in 8.0.29, 9.0.18, 10.0.6\n- dotnet-sdk (Bitnami): affected from 8.0.0; fixed in 8.0.29, 9.0.18, 10.0.6\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-2026-47304/ (Markdown: https://insights.sbomify.com/CVE-2026-47304/index.md)","id":"CVE-2026-47304","markdown":"https://insights.sbomify.com/CVE-2026-47304/index.md","name":"CVE-2026-47304","record":{"aliases":["BIT-dotnet-2026-47304","BIT-dotnet-sdk-2026-47304","ECHO-d94c-4487-662f","GHSA-g8r8-53c2-pm3f","MINI-7q2v-3hf9-p3g7","MINI-93h9-cw6p-63vv","MINI-g3vh-h9vm-jmcv","MINI-h67h-w6p7-w5qv","MINI-hgxx-r955-6xgg","MINI-j8x9-w4m9-cw8m","MINI-mr8r-v89x-rf8v","MINI-mww3-rv9r-7xfj","MINI-qgr5-28h8-g927","MINI-vvhm-v96r-wwfv","ROOT-APP-NUGET-CVE-2026-47304","UBUNTU-CVE-2026-47304"],"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 attacker can bypass security features by exploiting improper cryptographic signature verification in the .NET framework.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":".net","vendor":"microsoft"},{"product":".net_framework","vendor":"microsoft"},{"product":"visual_studio_2017","vendor":"microsoft"},{"product":"visual_studio_2019","vendor":"microsoft"},{"product":"visual_studio_2022","vendor":"microsoft"},{"product":"visual_studio_2026","vendor":"microsoft"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"},{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"description":"Improper verification of cryptographic signature in .NET allows an unauthorized attacker to bypass a security feature over a network.","ecosystems":["Bitnami","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 Security Feature Bypass Vulnerability","id":"CVE-2026-47304","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"microsoft:.net","products":["microsoft:.net","microsoft:.net_framework","microsoft:visual_studio_2017","microsoft:visual_studio_2019","microsoft:visual_studio_2022"],"type":"security_feature_bypass","year":"2026"},"n_packages":8,"n_references":1,"next":{"headline":"Visual Studio Remote Code Execution Vulnerability","id":"CVE-2026-47305"},"packages":[{"ecosystem":"Bitnami","fixed":["8.0.29","9.0.18","10.0.6"],"introduced":["8.0.0","9.0.0","10.0.0"],"last_affected":[],"package":"dotnet","purl":"pkg:bitnami/dotnet","source":"BIT-dotnet-2026-47304"},{"ecosystem":"Bitnami","fixed":["8.0.29","9.0.18","10.0.6"],"introduced":["8.0.0","9.0.0","10.0.0"],"last_affected":[],"package":"dotnet-sdk","purl":"pkg:bitnami/dotnet-sdk","source":"BIT-dotnet-sdk-2026-47304"},{"ecosystem":"NuGet","fixed":["10.0.10"],"introduced":["10.0.0"],"last_affected":[],"package":"System.Security.Cryptography.Xml","purl":null,"source":"GHSA-g8r8-53c2-pm3f"},{"ecosystem":"NuGet","fixed":["10.0.10"],"introduced":["10.0.0"],"last_affected":[],"package":"System.Security.Cryptography.Xml","purl":"pkg:nuget/System.Security.Cryptography.Xml","source":"GHSA-g8r8-53c2-pm3f"},{"ecosystem":"NuGet","fixed":["8.0.4"],"introduced":["8.0.0"],"last_affected":[],"package":"System.Security.Cryptography.Xml","purl":null,"source":"GHSA-g8r8-53c2-pm3f"},{"ecosystem":"NuGet","fixed":["8.0.4"],"introduced":["8.0.0"],"last_affected":[],"package":"System.Security.Cryptography.Xml","purl":"pkg:nuget/System.Security.Cryptography.Xml","source":"GHSA-g8r8-53c2-pm3f"},{"ecosystem":"NuGet","fixed":["9.0.18"],"introduced":["9.0.0"],"last_affected":[],"package":"System.Security.Cryptography.Xml","purl":null,"source":"GHSA-g8r8-53c2-pm3f"},{"ecosystem":"NuGet","fixed":["9.0.18"],"introduced":["9.0.0"],"last_affected":[],"package":"System.Security.Cryptography.Xml","purl":"pkg:nuget/System.Security.Cryptography.Xml","source":"GHSA-g8r8-53c2-pm3f"}],"prev":{"headline":"ASP.NET Core Elevation of Privilege Vulnerability","id":"CVE-2026-47303"},"products":[".NET 10.0 runtime",".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 2017 version 15.9 (includes 15.0 -
