{"id":"AZL-103095","summary":"CVE-2026-92091 affecting package python-jwcrypto 0.6.0-9","details":"A flaw was found in jwcrypto. The JWK.import_key() function validates the key_ops JWK member for duplicate values using an algorithm with O(n^2) time complexity, and the length of key_ops is not bounded. A remote, unauthenticated attacker can supply a JWK with a large key_ops array to an application that passes attacker-controlled key material to a public key-import API (reachable via ECDH-ES key agreement, OIDC dynamic client registration, DPoP, or ACME account key registration, among others) to consume excessive CPU time, resulting in a denial of service.","modified":"2026-09-22T05:33:10Z","published":"2026-09-16T08:16:40Z","upstream":["CVE-2026-92091"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92091"}],"affected":[{"package":{"name":"python-jwcrypto","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/python-jwcrypto"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"0.6.0-9"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-103095.json"}}],"schema_version":"1.9.0"}
