{"id":"AZL-98349","summary":"CVE-2026-37236 affecting package cloud-provider-kubevirt 0.5.1-6","details":"grpc-gateway v2.28.0 is vulnerable to Incorrect Access Control. The application processes the X-HTTP-Method-Override header in ServeMux.ServeHTTP without restricting allowed methods. When a POST request with Content-Type application/x-www-form-urlencoded includes this header, the request method is rewritten to an arbitrary attacker-supplied value before routing. This allows bypassing method-based access controls enforced by upstream proxies or WAFs.","modified":"2026-09-02T14:19:00.488385261Z","published":"2026-08-28T16:17:46Z","upstream":["CVE-2026-37236"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-37236"}],"affected":[{"package":{"name":"cloud-provider-kubevirt","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/cloud-provider-kubevirt"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"0.5.1-6"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-98349.json"}}],"schema_version":"1.9.0"}
