A network attacker who can reach NEF on the SBI can use a forged or arbitrary bearer token (e.g. `Authorization: Bearer not-a-real-token`) to read PFD application data via `GET /applications` and `GET /applications/{appID}`, and to create or delete PFD change-notification subscriptions via `POST /subscriptions` and `DELETE /subscriptions/{subID}`. Same root cause as the other NEF SBI findings: the route group is mounted without any inbound auth middleware. Unlike the OAM and traffic-influence groups, `nnef-pfdmanagement` IS declared in the runtime `ServiceList`, so this is the production-intended path that operators expect to be protected by `OAuth2 setting receive from NRF: true` -- and it is not.\n\n### Details\nValidated against the NEF container in the official Docker compose lab.\n- Source repo tag: `v4.2.1`\n- Running Docker image: `free5gc/nef:v4.2.0`\n- Runtime NEF commit: `5ce35eab`\n- Docker validation date: 2026-03-11\n\nNEF advertises `OAuth2 setting receive from NRF: true`, but the entire `nnef-pfdmanagement` route group is mounted with no inbound auth middle","public_affected_ranges":["<= 1.2.3"]}],"null_published_at":"2026-11-07T07:07:39.825Z","source_updated_at":"2026-06-08T23:48:32.000Z","source_disclosed_at":"2026-05-08T23:02:41.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-07T00:50:36.189Z"}],"next_cursor":null,"snapshot_revision":"42594"}
