CVE-2026-71479
Full vulnerability record from the local CVENow database.
Description
New API is a large language mode (LLM) gateway and artificial intelligence (AI) asset management system. Prior to 1.0.0-rc.18, user-controlled image n, video seconds and duration, max_tokens, max_completion_tokens, maxOutputTokens, audio duration, and billing-expression quantities can overflow conversions in common/quota_math.go and related settlement paths, allowing a low-privileged account with positive balance or an active subscription to turn a negative charge into account credit and potentially drain upstream funds. This issue is fixed in version 1.0.0-rc.18.

Antes de 1.0.0-rc.18, las cantidades controladas por el usuario de n de imagen, segundos y duración de video, max_tokens, max_completion_tokens, maxOutputTokens, duración de audio y expresión de facturación pueden desbordar las conversiones en common/quota_math.go y las rutas de liquidación relacionadas, permitiendo que una cuenta de bajo privilegio con saldo positivo o una suscripción activa convierta un cargo negativo en crédito de cuenta y potencialmente agote fondos ascendentes. Este problema está solucionado en la versión 1.0.0-rc.18."
