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-2026-25667 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- dotnet (Bitnami): affected from 8.0.0; fixed in 8.0.22, 9.0.11\n- dotnet-sdk (Bitnami): affected from 8.0.0; fixed in 8.0.22, 9.0.11\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-2026-25667/ (Markdown: https://insights.sbomify.com/CVE-2026-25667/index.md)","id":"CVE-2026-25667","markdown":"https://insights.sbomify.com/CVE-2026-25667/index.md","name":"CVE-2026-25667","record":{"aliases":["BIT-dotnet-2026-25667","BIT-dotnet-sdk-2026-25667","GHSA-jc8w-j2q2-vwjx","MINI-4xj4-jqfh-j879","MINI-9mr2-2hf7-crmq"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ASP.NET Core Kestrel","requires_auth":"none","summary":"Remote attackers can cause excessive CPU consumption in ASP.NET Core Kestrel via crafted QUIC packets, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":".net","vendor":"microsoft"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"ASP.NET Core Kestrel in Microsoft .NET 8.0 before 8.0.22 and .NET 9.0 before 9.0.11 allows a remote attacker to cause excessive CPU consumption by sending a crafted QUIC packet, because of an incorrect exit condition for HTTP/3 Encoder/Decoder stream processing.","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":"Denial of service in n/a","id":"CVE-2026-25667","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"microsoft:.net","products":["microsoft:.net"],"type":"denial_of_service","year":"2026"},"n_packages":2,"n_references":3,"next":{"headline":"Potential denial-of-service vulnerability in URLField via Unicode normalization on Windows","id":"CVE-2026-25673"},"packages":[{"ecosystem":"Bitnami","fixed":["8.0.22","9.0.11"],"introduced":["8.0.0","9.0.0"],"last_affected":[],"package":"dotnet","purl":"pkg:bitnami/dotnet","source":"BIT-dotnet-2026-25667"},{"ecosystem":"Bitnami","fixed":["8.0.22","9.0.11"],"introduced":["8.0.0","9.0.0"],"last_affected":[],"package":"dotnet-sdk","purl":"pkg:bitnami/dotnet-sdk","source":"BIT-dotnet-sdk-2026-25667"}],"prev":{"headline":"Authentication bypass for certain API calls","id":"CVE-2026-25660"},"products":["n/a"],"published":"2026-03-19","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-29","vendors":["n/a"]},"summary":"Remote attackers can cause excessive CPU consumption in ASP.NET Core Kestrel via crafted QUIC packets, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2026-25667/"}
