Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-36566 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.microsoft.commondatamodel:objectmodel (Maven): affected all versions; fixed in 1.7.4\n- com.microsoft.commondatamodel:objectmodel (Maven): affected all versions; fixed in 1.7.4\n- Microsoft.CommonDataModel.ObjectModel (NuGet): affected all versions; fixed in 1.7.4\n- Microsoft.CommonDataModel.ObjectModel (NuGet): affected all versions; fixed in 1.7.4\n- commondatamodel-objectmodel (PyPI): affected all versions; fixed in 1.7.4\n- commondatamodel-objectmodel (PyPI): affected all versions; fixed in 1.7.4\n- commondatamodel-objectmodel (PyPI): affected all versions; fixed in 1.7.4\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-2023-36566/ (Markdown: https://insights.sbomify.com/CVE-2023-36566/index.md)","id":"CVE-2023-36566","markdown":"https://insights.sbomify.com/CVE-2023-36566/index.md","name":"CVE-2023-36566","record":{"aliases":["GHSA-vm2m-7hpw-fpmq","PYSEC-2026-1261"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Common Data Model SDK","requires_auth":"low_privilege","summary":"Attackers can cause a denial of service in applications using the Microsoft Common Data Model SDK across multiple languages.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"common_data_model_sdk","vendor":"microsoft"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Microsoft Common Data Model SDK Denial of Service Vulnerability","ecosystems":["Maven","NuGet","PyPI"],"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":"Microsoft Common Data Model SDK Denial of Service Vulnerability","id":"CVE-2023-36566","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":7,"n_references":1,"next":{"headline":"Windows Deployment Services Information Disclosure Vulnerability","id":"CVE-2023-36567"},"packages":[{"ecosystem":"Maven","fixed":["1.7.4"],"introduced":["0"],"last_affected":[],"package":"com.microsoft.commondatamodel:objectmodel","purl":null,"source":"GHSA-vm2m-7hpw-fpmq"},{"ecosystem":"Maven","fixed":["1.7.4"],"introduced":["0"],"last_affected":[],"package":"com.microsoft.commondatamodel:objectmodel","purl":"pkg:maven/com.microsoft.commondatamodel/objectmodel","source":"GHSA-vm2m-7hpw-fpmq"},{"ecosystem":"NuGet","fixed":["1.7.4"],"introduced":["0"],"last_affected":[],"package":"Microsoft.CommonDataModel.ObjectModel","purl":null,"source":"GHSA-vm2m-7hpw-fpmq"},{"ecosystem":"NuGet","fixed":["1.7.4"],"introduced":["0"],"last_affected":[],"package":"Microsoft.CommonDataModel.ObjectModel","purl":"pkg:nuget/Microsoft.CommonDataModel.ObjectModel","source":"GHSA-vm2m-7hpw-fpmq"},{"ecosystem":"PyPI","fixed":["1.7.4"],"introduced":["0"],"last_affected":[],"package":"commondatamodel-objectmodel","purl":null,"source":"GHSA-vm2m-7hpw-fpmq"},{"ecosystem":"PyPI","fixed":["1.7.4"],"introduced":["0"],"last_affected":[],"package":"commondatamodel-objectmodel","purl":"pkg:pypi/commondatamodel-objectmodel","source":"GHSA-vm2m-7hpw-fpmq"},{"ecosystem":"PyPI","fixed":["1.7.4"],"introduced":["0"],"last_affected":[],"package":"commondatamodel-objectmodel","purl":"pkg:pypi/commondatamodel-objectmodel","source":"PYSEC-2026-1261"}],"prev":{"headline":"Microsoft Office Graphics Elevation of Privilege Vulnerability","id":"CVE-2023-36565"},"products":["Microsoft Common Data Model SDK for C#","Microsoft Common Data Model SDK for Java","Microsoft Common Data Model SDK for Python","Microsoft Common Data Model SDK for TypeScript"],"published":"2023-10-10","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":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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":"partial"},"state":"PUBLISHED","updated":"2025-04-14","vendors":["Microsoft"]},"summary":"Attackers can cause a denial of service in applications using the Microsoft Common Data Model SDK across multiple languages.","url":"https://insights.sbomify.com/CVE-2023-36566/"}
