It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-45490 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- dotnet (Bitnami): affected from 8.0.0; fixed in 8.0.28, 9.0.17, 10.0.9\n- dotnet-sdk (Bitnami): affected from 8.0.0; fixed in 8.0.28, 9.0.17, 10.0.9\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-2026-45490/ (Markdown: https://insights.sbomify.com/CVE-2026-45490/index.md)","id":"CVE-2026-45490","markdown":"https://insights.sbomify.com/CVE-2026-45490/index.md","name":"CVE-2026-45490","record":{"aliases":["BIT-dotnet-2026-45490","BIT-dotnet-sdk-2026-45490","GHSA-77gm-m6x5-jf4f","MINI-q752-6w4w-4fj5","MINI-qqfw-h489-7vq4","UBUNTU-CVE-2026-45490"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":".NET SDK","requires_auth":"low_privilege","summary":"An authorized local attacker can elevate privileges due to improper authorization in the .NET SDK.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":".net","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-266","name":"Incorrect Privilege Assignment"},{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-285","name":"Improper Authorization"}],"description":"Improper authorization in .NET allows an authorized attacker to elevate privileges 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 SDK Elevation of Privilege Vulnerability","id":"CVE-2026-45490","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"microsoft:.net","products":["microsoft:.net"],"type":"privilege_escalation","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":".NET Tampering Vulnerability","id":"CVE-2026-45491"},"packages":[{"ecosystem":"Bitnami","fixed":["8.0.28","9.0.17","10.0.9"],"introduced":["8.0.0","9.0.0","10.0.0"],"last_affected":[],"package":"dotnet","purl":"pkg:bitnami/dotnet","source":"BIT-dotnet-2026-45490"},{"ecosystem":"Bitnami","fixed":["8.0.28","9.0.17","10.0.9"],"introduced":["8.0.0","9.0.0","10.0.0"],"last_affected":[],"package":"dotnet-sdk","purl":"pkg:bitnami/dotnet-sdk","source":"BIT-dotnet-sdk-2026-45490"}],"prev":{"headline":"Microsoft Edge (Chromium-based) Spoofing Vulnerability","id":"CVE-2026-45489"},"products":[".NET 10.0",".NET 8.0",".NET 9.0"],"published":"2026-06-09","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":"2026-09-24","vendors":["Microsoft"]},"summary":"An authorized local attacker can elevate privileges due to improper authorization in the .NET SDK.","url":"https://insights.sbomify.com/CVE-2026-45490/"}
