The create path then calls `provisioningOfTrafficRoutingInfo(smPolicy, appID, routeReq, ...)` with `routeReq == nil` and dereferences `routeReq.RouteToLocs` (and other fields) without a nil check, causing `runtime error: invalid memory address or nil pointer dereference`. Gin recovery converts the panic into `HTTP 500`.\n\nThe trigger is a single valid authenticated request -- changing only `suppFeat` from `\"0\"` to `\"1\"` flips the same shape of POST from a normal `201 Created` into a panic-driven `500`.\n\nThis endpoint requires a valid `npcf-policyauthorization` OAuth2 access token (PR:L). The PCF process is not killed (Gin recovers); the realized impact is per-request panic-DoS on the app-session create path.\n\n### Details\nValidated against the PCF container in the official Docker compose lab.\n- Source repo tag: `v4.2.1`\n- PCF endpoint: `http://10.100.200.9:8000`\n- Validation date: 2026-03-12\n\nVulnerable handl","public_affected_ranges":["< 1.4.3"]}],"null_published_at":"2026-11-07T07:07:39.807Z","source_updated_at":"2026-06-08T23:47:08.000Z","source_disclosed_at":"2026-05-08T22:40:11.000Z","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"}
