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.","state":0,"publishedAt":"2026-10-22T17:16:58.577+00:00","modifiedAt":"2026-10-23T15:17:26.763+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","score":9.1,"severity":"CRITICAL"}],"references":["https://github.com/better-auth/better-auth/commit/ac54bfd67821a7607533af2059858b12bc54e26a","https://github.com/better-auth/better-auth/pull/11494","https://github.com/better-auth/better-auth/releases/tag/v1.7.7","https://github.com/better-auth/better-auth/security/advisories/GHSA-965c-763c-88jm"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-114607","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-287"],"productCriteria":[],"sourceDates":{"published":"2026-10-22T17:16:58.577","lastModified":"2026-10-23T15:17:26.763"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
