Detailsinfo

A vulnerability classified as critical was found in NASA-AMMOS PlanDev (the affected version is unknown). This vulnerability affects the function getHasuraSession of the file sequencing-server/src/app.ts of the component Authorization Middleware. The manipulation of the argument session_variables with an unknown input leads to a improper authorization vulnerability. The CWE definition for the vulnerability is CWE-285. The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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. 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.

The advisory is available at github.com. This vulnerability was named CVE-2026-71214 since 08/05/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are known, but there is no available exploit.
