{"id":"CVE-2026-58269","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-58269","generatedAt":"2026-10-28T02:21:17.258Z","title":"An attacker with stolen or phished credentials can bypass 2FA in a single request.","description":"Sync-in Server is an open-source platform for file storage, sharing, collaboration, and syncing. Prior to version 2.4.0, `POST /api/auth/token` authenticates with username and password only, then calls `getTokens()`, which returns full access and refresh JWTs without checking whether the account has TOTP 2FA enabled. An attacker with stolen or phished credentials can bypass 2FA in a single request. The parallel login endpoint (`POST /api/auth/login`) correctly enforces 2FA by calling `setCookies(user, res, true)`, which gates on `user.twoFaEnabled`. Version 2.4.0 patches the issue.","published":"2026-09-21T20:17:27.000Z","lastModified":"2026-09-24T23:17:12.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},"cwe":["CWE-288"],"affected":[],"epss":{"score":0.00274,"percentile":0.19622,"date":"2026-10-26","history":[{"date":"2026-09-22","score":0.00225,"percentile":0.13469}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.27%).
