Dsf Fhir Server
Monthly
Indefinite OIDC session persistence in the Data Sharing Framework (DSF) FHIR and BPE servers prior to 2.1.0 allows any person with physical access to an authenticated browser session to access DSF resources under the original user's permissions, even after the OIDC access token has expired. The root cause is the absence of a maximum inactivity timeout in the Jetty-based session handler for OIDC browser sessions. No public exploit code exists and no active exploitation has been identified; EPSS stands at 0.02% (4th percentile), consistent with the physical access requirement.
