CVE-2022-39273Network attack vector

Remote impersonation via hardcoded OAuth secret

Published Oct 6, 2022 · Updated Apr 23, 2025

Hard-coded credential vulnerability in Flyte FlyteAdmin before 1.1.44 allows remote attackers to impersonate Flyte Propeller via OAuth requests. The built-in authorization server accepts a shipped hashed client secret when staticClients remains unchanged, allowing requests to be treated as Propeller traffic. The exposure requires FlyteAdmin's internal authorization server without ExternalAuthorizationServer; attackers can then read or modify workflow-control data, while external authorization deployments are not affected.
