{"id":"CVE-2026-64865","aliases":["GHSA-j6gc-4893-qwmp","GO-2026-6243"],"url":"https://o3.security/vulnerability/CVE-2026-64865","summary":"New API: Redis user quota cache overwrite via PUT /api/user/self allows quota bypass","details":"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. This issue is fixed in version 1.0.0-rc.16.","published":"2026-08-17T16:13:37.664Z","modified":"2026-08-19T03:48:35.867506423Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Go","name":"github.com/QuantumNous/new-api","fixedVersion":"1.0.0-rc.16"}],"fix":{"url":"https://github.com/QuantumNous/new-api/commit/dfc0d6324b40c1d6c2972e524409f933541bfb0f","label":"QuantumNous/new-api@dfc0d63"},"references":[{"type":"WEB","url":"https://github.com/QuantumNous/new-api/releases/tag/v1.0.0-rc.16"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64865.json"},{"type":"ADVISORY","url":"https://github.com/QuantumNous/new-api/security/advisories/GHSA-j6gc-4893-qwmp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64865"},{"type":"FIX","url":"https://github.com/QuantumNous/new-api/commit/dfc0d6324b40c1d6c2972e524409f933541bfb0f"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T03:48:35.867506423Z"}}
