Official description

The Aerie/PlanDev sequencing-server's authorization middleware (sequencing-server/src/app.ts) derives the caller's Hasura session role via getHasuraSession, which prefers a session_variables object taken directly from the client-supplied JSON request body over the Authorization header's JWT claims, with no verification that the request actually originated from Hasura.
