DescriptionThe 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. By setting {"session_variables":{"x-hasura-role":"aerie_admin"}} in the body of a request to POST /command-expansion/put-expansion with no Authorization header, an unauthenticated attacker satisfies the role check and can insert arbitrary expansion rules into sequencing.expansion_rule, which govern how spacecraft activities are translated into commands. Separately, POST /put-dictionary is explicitly listed in the ENDPOINTS_WHITELIST and is exempt from any authentication, allowing unauthenticated writes of command dictionaries.
