This medium-severity CVE scores 6.1 under NVD CVSS v3. EPSS exploit probability: 0.4%, top 69% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Better Auth is an authentication library for TypeScript. An open redirect vulnerability has been identified in the verify email endpoint of all versions of Better Auth prior to v1.1.6, potentially allowing attackers to redirect users to malicious websites. This issue affects users relying on email verification links generated by the library. The verify email callback endpoint accepts a callbackURL parameter. Unlike other verification methods, email verification only uses JWT to verify and redirect without proper validation of the target domain. The origin checker is bypassed in this scenario because it only checks for POST requests. An attacker can manipulate this parameter to redirect users to arbitrary URLs controlled by the attacker. Version 1.1.6 contains a patch for the issue.
