Description
New API is a large language mode (LLM) gateway and artificial intelligence (AI) asset management system. Prior to 1.0.0-rc.11, POST /api/stripe/webhook, POST /api/creem/webhook, and POST /api/waffo/webhook read and log full request bodies before signature validation in router/api-router.go and the payment controllers, allowing an unauthenticated attacker to cause memory pressure, container restarts, or disk exhaustion without forging a successful payment. This issue is fixed in version 1.0.0-rc.11.
