CyberRota Analysis
AI-GeneratedThe vulnerability affects Better Auth versions prior to 1.4.5, which utilize the rou3 router library that improperly normalizes URL paths, allowing attackers to bypass security configurations like disabledPaths and path-based rate limits by exploiting extra slashes in the URL. This could lead to unauthorized access or abuse of the application. Organizations using affected versions of Better Auth should prioritize patching to mitigate potential exploitation risks.

Original NVD Description
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 attackers to bypass disabledPaths configuration and path-based rate limits by submitting requests with extra slashes in the URL path. The issue does not apply in deployments where the proxy or platform normalizes URLs by collapsing multiple slashes.
