CVE-2025-71401

The connected CVE entry describes a vulnerability in better-auth (npm) before 1.4.2 where an external request can configure baseURL when it is not defined (e.g., BETTER_AUTH_URL unset). An attacker who can trigger the first request after startup can poison the router’s base path, causing all rout...

CVE-2025-71399

CVE-2025-71399 affects Better Auth prior to version 1.4.5, which ships a vulnerable rou3 router. In rou3, path normalization removes empty segments, causing /path, //path, and ///path to resolve to the same route. This enables an attacker to bypass disabledPaths configuration and path-based rate ...

CVE-2025-71399

Better Auth relies on better-call, which uses the rou3 router library. In affected versions of rou3, paths are normalized by removing empty segments, so /path, //path, and ///path resolve to the same route. In Better Auth versions prior to 1.4.5 which bundles the fixed rou3, this can allow...

CVE-2025-71399: Improper Input Validation

Better Auth relies on better-call, which uses the rou3 router library. In affected versions of rou3, paths are normalized by removing empty segments, so /path, //path, and ///path resolve to the same route. In Better Auth versions prior to 1.4.5 which bundles the fixed rou3, this can allow...

CVE-2025-71401: Allocation of Resources Without Limits or Throttling

better-auth npm before 1.4.2 allows an external request to configure baseURL when it is not otherwise defined e.g., BETTERAUTHURL is unset. An attacker able to make the very first request to the server after startup can poison the router's base path, causing all routes to return 404 for all users...
