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-2026-66803 in the wild and no public exploit code.\n\nAffected product: Microsoft Azure Cosmos DB. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-66803/ (Markdown: https://insights.sbomify.com/CVE-2026-66803/index.md)","id":"CVE-2026-66803","markdown":"https://insights.sbomify.com/CVE-2026-66803/index.md","name":"CVE-2026-66803","record":{"aliases":["GHSA-ww36-75qc-rhmx"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Azure Cosmos DB","requires_auth":"none","summary":"An unauthorized attacker can execute code over the network due to improper access control in Azure Cosmos DB.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"azure_cosmos_db","vendor":"microsoft"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"Improper access control in Azure Cosmos DB allows an unauthorized attacker to execute code over a network.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Azure Cosmos DB Remote Code Execution Vulnerability","id":"CVE-2026-66803","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Windows Cross Device Service Elevation of Privilege Vulnerability","id":"CVE-2026-66804"},"packages":[],"prev":{"headline":"Windows Device Health Attestation (DHA) Remote Code Execution Vulnerability","id":"CVE-2026-66802"},"products":["Azure Cosmos DB"],"published":"2026-07-30","related":[{"cvss_score":9.6,"headline":"Azure Cosmos DB Elevation of Privilege Vulnerability","id":"CVE-2026-87701","kev_date_added":null,"published":"2026-09-17"},{"cvss_score":8.5,"headline":"Azure Cosmos DB Spoofing Vulnerability","id":"CVE-2026-69857","kev_date_added":null,"published":"2026-09-03"},{"cvss_score":8.3,"headline":"Azure Cosmos DB Spoofing Vulnerability","id":"CVE-2025-64675","kev_date_added":null,"published":"2025-12-18"}],"sources":[{"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":"total"},"state":"PUBLISHED","updated":"2026-10-28","vendors":["Microsoft"]},"summary":"An unauthorized attacker can execute code over the network due to improper access control in Azure Cosmos DB.","url":"https://insights.sbomify.com/CVE-2026-66803/"}
