{"id":"GHSA-jr54-jwhj-55gp","summary":"NocoDB: User Enumeration via Sign-In Timing","details":"### Summary\nSign-in response timing differed between known and unknown email addresses because\nthe unknown-user branch returned without performing a password hash comparison.\n\n### Details\nThe unknown-user branch in `auth.service.ts` now performs a `bcrypt.compare` against\na fixed dummy hash so the response time of failed sign-ins is approximately\nindependent of whether the address exists. Rate limiting on the sign-in endpoint is\nimplemented in the Enterprise build only and is not affected by this advisory.\n\n### Impact\nA network-positioned attacker could enumerate registered email addresses by timing\nsign-in responses. Exploitation requires only the ability to send unauthenticated\nsign-in requests.\n\n### Credit\nThis issue was reported by [@AndyAnh174](https://github.com/AndyAnh174).","aliases":["CVE-2026-47380"],"modified":"2026-07-20T21:30:40.674946552Z","published":"2026-06-05T16:03:55Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-06-05T16:03:55Z","nvd_published_at":"2026-06-23T21:16:59Z","cwe_ids":["CWE-208","CWE-307"]},"references":[{"type":"WEB","url":"https://github.com/nocodb/nocodb/security/advisories/GHSA-jr54-jwhj-55gp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47380"},{"type":"PACKAGE","url":"https://github.com/nocodb/nocodb"},{"type":"WEB","url":"https://github.com/nocodb/nocodb/releases/tag/2026.04.1"}],"affected":[{"package":{"name":"nocodb","ecosystem":"npm","purl":"pkg:npm/nocodb"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2026.04.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-jr54-jwhj-55gp/GHSA-jr54-jwhj-55gp.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
