      <title>CVE-2026-114607 — better-auth: OAuth state can be used as a Magic Link to sign in as another user</title>
      <link>https://db.gcve.eu/vuln/cve-2026-114607</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; better-auth&lt;/p&gt;
&lt;p&gt;Better Auth is an authentication and authorization library for TypeScript. From 1.4.0-beta.18 until 1.7.7, deployments that enable Magic Link with storeToken set to plain, or with storeToken set to hashed and the global verification.storeIdentifier setting also set to hashed, enable a built-in social or Generic OAuth provider, and use account.storeStateStrategy set to database can accept an OAuth sign-in state value as a Magic Link token. These settings can cause Magic Link verification records and OAuth state to resolve to the same stored identifier, allowing an unauthenticated attacker to start OAuth sign-in for a known email address and redeem the returned state through Magic Link without controlling the mailbox or completing the provider callback. The attacker can obtain a normal session for an existing user, or create an account incorrectly marked as email verified when sign-up is enabled. This issue is fixed in version 1.7.7.&lt;/p&gt;</description>
