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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:N/VI:H/VA:L/SC:N/SI:N/SA:N","score":6.0},"cvss_v3":null,"cwes":["CWE-362"],"references":["https://github.com/QuantumNous/new-api/commit/dfc0d6324b40c1d6c2972e524409f933541bfb0f","https://github.com/QuantumNous/new-api/releases/tag/v1.0.0-rc.16","https://github.com/QuantumNous/new-api/security/advisories/GHSA-j6gc-4893-qwmp"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:10.689564601+00:00"},"epss":{"cve":"CVE-2026-64865","score":0.00295,"percentile":0.22133,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-j6gc-4893-qwmp","url":"https://osv.dev/vulnerability/GHSA-j6gc-4893-qwmp","summary":"New API: Redis user quota cache overwrite via PUT /api/user/self allows quota bypass","modified":"2026-08-18T15:11:00.903177226Z","packages":[{"ecosystem":"Go","name":"github.com/QuantumNous/new-api","purl":"pkg:golang/github.com/QuantumNous/new-api","ranges":["<1.0.0-rc.16"],"fixed":["1.0.0-rc.16"]}]},{"id":"GO-2026-6243","url":"https://osv.dev/vulnerability/GO-2026-6243","summary":"New API: Redis user quota cache overwrite via PUT /api/user/self allows quota bypass in github.com/QuantumNous/new-api","modified":"2026-08-18T15:00:26.862409189Z","packages":[{"ecosystem":"Go","name":"github.com/QuantumNous/new-api","purl":"pkg:golang/github.com/QuantumNous/new-api","ranges":["<1.0.0-rc.16"],"fixed":["1.0.0-rc.16"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
