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-2026-96230 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- Microsoft.AspNetCore.Components.WebAssembly.Server (NuGet): affected from 10.0.0; fixed in 10.0.13\n- Microsoft.AspNetCore.Components.WebAssembly.Server (NuGet): affected from 10.0.0; fixed in 10.0.13\n- Microsoft.AspNetCore.Components.WebAssembly.Server (NuGet): affected from 11.0.0-preview.1; fixed in 11.0.0-rc.2\n- Microsoft.AspNetCore.Components.WebAssembly.Server (NuGet): affected from 11.0.0-preview.1; fixed in 11.0.0-rc.2\n- Microsoft.AspNetCore.Components.WebAssembly.Server (NuGet): affected from 8.0.0; fixed in 8.0.32\n- Microsoft.AspNetCore.Components.WebAssembly.Server (NuGet): affected from 8.0.0; fixed in 8.0.32\n- Microsoft.AspNetCore.Components.WebAssembly.Server (NuGet): affected from 9.0.0; fixed in 9.0.21\n- Microsoft.AspNetCore.Components.WebAssembly.Server (NuGet): affected from 9.0.0; fixed in 9.0.21\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-2026-96230/ (Markdown: https://insights.sbomify.com/CVE-2026-96230/index.md)","id":"CVE-2026-96230","markdown":"https://insights.sbomify.com/CVE-2026-96230/index.md","name":"CVE-2026-96230","record":{"aliases":["GHSA-qjpx-jqm5-h2c4","UBUNTU-CVE-2026-96230"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"ASP.NET Core","requires_auth":"none","summary":"An attacker can execute code over the network via cross-site scripting in ASP.NET Core, requiring immediate patching for developers and administrators.","user_interaction":"required","vuln_class":"xss"},"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-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Improper neutralization of input during web page generation ('cross-site scripting') in ASP.NET Core allows an unauthorized attacker to execute code over a network.","ecosystems":["NuGet"],"exploits":{"exploitdb":0,"first_seen":"2026-10-14","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-10-14T22:26:00Z","kind":"github_poc","ref":"https://github.com/codevalai/microsoft-security-advisory-cv","stars":0,"title":"Autonomous submission for \"Microsoft Security Advisory CVE-2026-96230 - ASP.NET Core Remote Code Execution Vulnerability\" (MSRC / GitHub Security Advisory)"}],"tier":"poc_unverified"},"has_fix":true,"headline":"ASP.NET Core Remote Code Execution Vulnerability","id":"CVE-2026-96230","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":null,"products":[],"type":"xss","year":"2026"},"n_packages":8,"n_references":1,"next":{"headline":".NET Elevation of Privilege Vulnerability","id":"CVE-2026-96231"},"packages":[{"ecosystem":"NuGet","fixed":["10.0.13"],"introduced":["10.0.0"],"last_affected":[],"package":"Microsoft.AspNetCore.Components.WebAssembly.Server","purl":null,"source":"GHSA-qjpx-jqm5-h2c4"},{"ecosystem":"NuGet","fixed":["10.0.13"],"introduced":["10.0.0"],"last_affected":[],"package":"Microsoft.AspNetCore.Components.WebAssembly.Server","purl":"pkg:nuget/Microsoft.AspNetCore.Components.WebAssembly.Server","source":"GHSA-qjpx-jqm5-h2c4"},{"ecosystem":"NuGet","fixed":["11.0.0-rc.2"],"introduced":["11.0.0-preview.1"],"last_affected":[],"package":"Microsoft.AspNetCore.Components.WebAssembly.Server","purl":null,"source":"GHSA-qjpx-jqm5-h2c4"},{"ecosystem":"NuGet","fixed":["11.0.0-rc.2"],"introduced":["11.0.0-preview.1"],"last_affected":[],"package":"Microsoft.AspNetCore.Components.WebAssembly.Server","purl":"pkg:nuget/Microsoft.AspNetCore.Components.WebAssembly.Server","source":"GHSA-qjpx-jqm5-h2c4"},{"ecosystem":"NuGet","fixed":["8.0.32"],"introduced":["8.0.0"],"last_affected":[],"package":"Microsoft.AspNetCore.Components.WebAssembly.Server","purl":null,"source":"GHSA-qjpx-jqm5-h2c4"},{"ecosystem":"NuGet","fixed":["8.0.32"],"introduced":["8.0.0"],"last_affected":[],"package":"Microsoft.AspNetCore.Components.WebAssembly.Server","purl":"pkg:nuget/Microsoft.AspNetCore.Components.WebAssembly.Server","source":"GHSA-qjpx-jqm5-h2c4"},{"ecosystem":"NuGet","fixed":["9.0.21"],"introduced":["9.0.0"],"last_affected":[],"package":"Microsoft.AspNetCore.Components.WebAssembly.Server","purl":null,"source":"GHSA-qjpx-jqm5-h2c4"},{"ecosystem":"NuGet","fixed":["9.0.21"],"introduced":["9.0.0"],"last_affected":[],"package":"Microsoft.AspNetCore.Components.WebAssembly.Server","purl":"pkg:nuget/Microsoft.AspNetCore.Components.WebAssembly.Server","source":"GHSA-qjpx-jqm5-h2c4"}],"prev":{"headline":".NET Information Disclosure Vulnerability","id":"CVE-2026-96229"},"products":["Microsoft Visual Studio 2022 version 17.14","Microsoft Visual Studio 2026 version 18.10","Microsoft.AspNetCore.Components.WebAssembly.Server"],"published":"2026-10-13","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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-29","vendors":["Microsoft"]},"summary":"An attacker can execute code over the network via cross-site scripting in ASP.NET Core, requiring immediate patching for developers and administrators.","url":"https://insights.sbomify.com/CVE-2026-96230/"}
