Last modified

CVE-2026-64865 is a medium-severity vulnerability rated 6/10 on the CVSS scale. New API is a large language mode (LLM) gateway and artificial intelligence (AI) asset management system. Prior to 1.0.0-rc.16, repeated PUT /api/user/self requests that update language or sidebar_modules can race relay billing because controller/user.go calls User.Update and updateUserCache performs a full RedisHSetObj write to user:.Quota, overwriting concurrent HINCRBY deductions and allowing an authenticated user to keep cached quota artificially high. EPSS estimates a 0.24% chance of exploitation in the next 30 days.
