directusnpmDescription
Summary
When GRAPHQL_INTROSPECTION=false is configured, Directus correctly blocks standard GraphQL introspection queries (__schema, __type). However, the server_specs_graphql resolver on the /graphql/system endpoint returns an equivalent SDL representation of the schema and was not subject to the same restriction. This allowed the introspection control to be bypassed, exposing schema structure (collection names, field names, types, and relationships) to unauthenticated users at the public permission level, and to authenticated users at their permitted permission level.
Impact
Administrators who set GRAPHQL_INTROSPECTION=false to hide schema structure from clients would have had a false sense of security, as equivalent schema information remained accessible via the SDL endpoint without authentication.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for directus, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update directus to 11.16.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-wxwm-3fxv-mrvx is resolved across your whole dependency graph.
Workarounds
Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.
