auth-js is an isomorphic Javascript library for Supabase Auth. Prior to version 2.70.0, the library functions getUserById, deleteUser, updateUserById, listFactors and deleteFactor did not require the user supplied values to be valid UUIDs. This could lead to a URL path traversal, resulting in the wrong API function being called. Implementations that follow security best practice and validate user controlled inputs, such as the userId are not affected by this. This issue has been patched in version 2.70.0.

GHSA-8r88-6cj9-9fh5 — auth-js Vulnerable to Insecure Path Routing from Malformed User Input

Affected: npm: @supabase/auth-js

### Impact The library functions `getUserById`, `deleteUser`, `updateUserById`, `listFactors` and `deleteFactor` did not require the user supplied values to be valid UUIDs. This could lead to a URL path traversal, resulting in the wrong API function being called.

Implementations that follow security best practice and validate user controlled inputs, such as the `userId` are not affected by this.

### Patches Strict value checks have been added to all affected functions. These functions now require that the `userId` and `factorId` parameters MUST be valid UUID (v4).

**Patched version:** >= 2.69.1

### Workarounds Implementations that follow security best practice and validate user controlled inputs, such as the `userId` are not affected by this. It is recommended that users of the auth-js library always follow security best practice and validate all inputs, before passing these to other functions or libraries.
