GHSA-7JP2-5H22-M432

Auth0 Symfony SDK Does Not Properly Handle File Types in Bulk User Import

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.

Acknowledgement

Okta would like to thank Mohamed Amine Saidani (pwni) for discovering this vulnerability.

The application accepts file uploads without adequately restricting the file type or content. Typical impact: remote code execution if the uploaded file can be served and executed on the server.

GHSA-7JP2-5H22-M432 has a CVSS score of 3.3 (Low). The vector is network-reachable, high privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (5.5.0); upgrading removes the vulnerable code path.

Upgrade Auth0/symfony to version 5.5.0 or greater.

1. What is GHSA-7JP2-5H22-M432? GHSA-7JP2-5H22-M432 is a low-severity unrestricted upload of dangerous file types vulnerability in auth0/symfony (composer), affecting versions >= 2.0.2, <= 5.4.1. It is fixed in 5.5.0. The application accepts file uploads without adequately restricting the file type or content.
2. How severe is GHSA-7JP2-5H22-M432? GHSA-7JP2-5H22-M432 has a CVSS score of 3.3 (Low). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of auth0/symfony are affected by GHSA-7JP2-5H22-M432? auth0/symfony (composer) versions >= 2.0.2, <= 5.4.1 is affected.
4. Is there a fix for GHSA-7JP2-5H22-M432? Yes. GHSA-7JP2-5H22-M432 is fixed in 5.5.0. Upgrade to this version or later.
5. Is GHSA-7JP2-5H22-M432 exploitable, and should I be worried? Whether GHSA-7JP2-5H22-M432 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether GHSA-7JP2-5H22-M432 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix GHSA-7JP2-5H22-M432? Upgrade auth0/symfony to 5.5.0 or later.
