Description
Mythic before 3.4.0.60 contains a broken hasura permission filter on the payload_build_step table with an always-satisfied _or condition that bypasses operation-scoped access controls. Authenticated operators and spectators can query payload_build_step to read step_stdout, step_stderr, step_name, and step_description across all operations on the server.
