CVE-2025-48370
auth-js is an isomorphic Javascript library for Supabase Auth.
Overview
CVE-2025-48370 is a known-severity vulnerability. It was published on May 27, 2025.
Technical description
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.
