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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-58269)\n\nAffected packages:\n\n- `@sync-in/server <= 2.3.0`\n\nPatched in:\n\n- `@sync-in/server 2.4.0`\n\nSource: https://github.com/advisories/GHSA-92cr-jxw4-5wjg","depth":"midnight","depthScore":57,"depthScoreParts":{"impact":44.6,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":210434,"id":"CVE-2026-58269","ts":1790290512683,"field":"exploit_available","old":"false","new":"true"}]}
