• CVE-2025-58769: 0.35% estimated exploitation activity in the next 30 days; percentile 28.72 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

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-PHP SDK, versions between v3.3.0 and v8.16.0, or 2. Applications using the following SDKs that rely on the Auth0-PHP SDK versions between v3.3.0 and v8.16.0: a. Auth0/symfony, b. Auth0/laravel-auth0, c. Auth0/wordpress. Fix Upgrade Auth0/Auth0-PHP to version 8.17.0 or greater. Acknowledgement Okta would like to thank Mohamed Amine Saidani (pwni) for discovering this vulnerability.

# Patch Next advisory brief: CVE-2025-58769

Advisory: auth0-PHP SDK Does Not Properly Handle File Types in Bulk User Import
IDs: CVE-2025-58769, GHSA-9mh6-g99m-ppcw
Record: https://patchnext.com/advisories/cve-2025-58769 (revision 1, source checked 26 Oct 2026, 14:34 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Low (CVSS 3.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: auth0/auth0-php 8.17.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist auth0/auth0-php: affected >= 3.3.0, <= 8.16.0; fixed in 8.17.0

## Suggested inspection (read-only)
- Packagist auth0/auth0-php: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on auth0/auth0-php.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-9mh6-g99m-ppcw (GitHub-reviewed advisory GHSA-9mh6-g99m-ppcw lists affected ranges: Packagist auth0/auth0-php >=3.3.0 <=8.16.0)
