AI risk analysis
- Summary
- The flaw allows an attacker to bypass authentication by manipulating the session_variables object in the request body, overriding the Authorization header's JWT claims without verification.
- Exploitability
- Exploitation is relatively easy if an attacker can control the request body, as no origin verification is performed.
- Blast radius
- If exploited, this could lead to unauthorized access and potential full system compromise, as the attacker would have elevated privileges.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Disable the affected feature or restrict access to the endpoint where the session_variables object is used.

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.
