AI risk analysis

Summary: The flaw allows an attacker to bypass authentication by manipulating the session_variables object in the request body instead of using the Authorization header's JWT claims.
Exploitability: Exploitation requires control over the client-supplied JSON request body and no verification of Hasura origin, making it relatively easy for attackers with access to this vector.
Blast radius: If exploited, this could lead to unauthorized access, data modification, or full system compromise, depending on the server's permissions and configurations.
Prioritized remediation: Implement strict validation and verification of JWT claims from the Authorization header before using any session-related variables in the request body.

NVD 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.
