CVE-2026-111682: EFAK 5.0.0 through 5.1.0 Missing Authorization via /api/model-config Exposes API Keys

EFAK 5.0.0 through 5.1.0 contains a missing authorization vulnerability that allows authenticated low-privilege users to read LLM provider API keys through the /api/model-config REST API. Attackers with any ROLEUSER account can query /api/model-config/page or /api/model-config/{id} to retrieve unmasked keys, enabling provider account access and incurred costs.
