CyberRota Analysis
AI-GeneratedVersions of better-auth from 1.1.3 to 1.6.22, as well as pre-release versions from 1.7.0-beta.0 to 1.7.0-beta.10, are vulnerable to account takeover due to a flaw in the magic-link and email-OTP sign-in process. This vulnerability allows an attacker to hijack a victim's account by registering it with their email and a chosen password, enabling persistent access when the legitimate user attempts to sign in. Organizations using these affected versions should prioritize immediate updates to versions 1.6.22 or 1.7.0-beta.10 to mitigate this risk.

Original NVD Description
better-auth versions >= 1.1.3 and < 1.6.22 (and pre-release versions >= 1.7.0-beta.0 and < 1.7.0-beta.10) are vulnerable to account takeover via pre-account hijacking on magic-link and email-OTP sign-in when open email/password registration is enabled. An attacker registers an account with the victim's email address and an attacker-chosen password; the account remains unverified. When the legitimate owner later signs in via the magic-link or email-OTP passwordless flow, the account is marked verified without removing the pre-existing password or revoking existing sessions, so the attacker's password remains valid, granting persistent access to the victim's account. Fixed in 1.6.22 and 1.7.0-beta.10.
