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-2025-59273 in the wild and no public exploit code.\n\nAffected product: Microsoft Azure Event Grid System. 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-2025-59273/ (Markdown: https://insights.sbomify.com/CVE-2025-59273/index.md)","id":"CVE-2025-59273","markdown":"https://insights.sbomify.com/CVE-2025-59273/index.md","name":"CVE-2025-59273","record":{"aliases":["GHSA-5wpc-p9f6-h8mw"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Azure Event Grid","requires_auth":"none","summary":"An unauthorized attacker can elevate privileges in Azure Event Grid due to improper access control, requiring immediate patching.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"azure_event_grid","vendor":"microsoft"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"Improper access control in Azure Event Grid allows an unauthorized attacker to elevate privileges 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 Event Grid System Elevation of Privilege Vulnerability","id":"CVE-2025-59273","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Windows Authentication Elevation of Privilege Vulnerability","id":"CVE-2025-59275"},"packages":[],"prev":{"headline":"Copilot Information Disclosure Vulnerability","id":"CVE-2025-59272"},"products":["Azure Event Grid System"],"published":"2025-10-23","related":[{"cvss_score":7.7,"headline":"Azure Event Grid Spoofing Vulnerability","id":"CVE-2026-83947","kev_date_added":null,"published":"2026-10-08"}],"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":"2026-02-26","vendors":["Microsoft"]},"summary":"An unauthorized attacker can elevate privileges in Azure Event Grid due to improper access control, requiring immediate patching.","url":"https://insights.sbomify.com/CVE-2025-59273/"}
