Summary
DSF: Missing Session Timeout for OIDC Sessions
Details

The Data Sharing Framework (DSF) implements a distributed process engine based on the BPMN 2.0 and FHIR R4 standards. Prior to 2.1.0, OIDC-authenticated sessions had no configured maximum inactivity timeout. Sessions persisted indefinitely after login, even after the OIDC access token expired. This vulnerability is fixed in 2.1.0.
