    External Control of File Name or Path

    better-auth is a The most comprehensive authentication library for TypeScript.

    Affected versions of this package are vulnerable to External Control of File Name or Path via the getBaseURL function. An attacker can cause all routes to return 404 errors for all users by sending a crafted first request with manipulated X-Forwarded-Host and X-Forwarded-Proto headers, which poisons the router's basePath.

    Note: This is only exploitable if the baseURL is not explicitly configured and the attacker is able to make the very first request to the server after startup.

    How to fix External Control of File Name or Path?

    Upgrade better-auth to version 1.4.3 or higher.
