Description

Overview

In applications built with the Auth0-PHP SDK, the Bulk User Import endpoint does not validate the file path wrapper or value. Without proper validation, affected applications may accept arbitrary file paths or URLs.

Am I affected?

You are affected by this vulnerability if you meet the following preconditions:

  1. Applications using the Auth0 laravel-auth0 SDK with version between 4.0.0 and 7.18.0,
  2. Auth0 laravel-auth0 SDK uses the Auth0-PHP SDK with versions between 3.3.0 and 8.16.0.

Fix

Upgrade Auth0 laravel-auth0 SDK to version 7.19.0 or greater.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for auth0/login, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update auth0/login to 7.19.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hjfh-5jmm-xr24 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
