Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

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 Symfony SDK with versions between 2.0.2 and 5.4.1,
  2. Auth0 Symfony SDK uses the Auth0-PHP SDK with versions between 3.3.0 and 8.16.0.

Fix

Upgrade Auth0/symfony to version 5.5.0 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/symfony, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update auth0/symfony to 5.5.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7jp2-5h22-m432 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.
