CVE-2025-58769: 
PHP vulnerability analysis and mitigation

CVE-2025-58769 affects the auth0-PHP SDK, an SDK for Auth0 Authentication and Management APIs. The vulnerability was discovered in versions 3.3.0 through 8.16.0, where the Bulk User Import endpoint fails to validate file-path wrapper or value properly. The vulnerability was disclosed on October 1, 2025, and affects applications that either directly use the Auth0-PHP SDK or indirectly rely on those versions through Auth0/symfony, Auth0/laravel-auth0, or Auth0/wordpress SDKs (Auth0 Advisory).

The vulnerability stems from improper validation of file paths in the Bulk User Import functionality. Without proper validation, affected applications may accept arbitrary file paths or URLs, potentially leading to unauthorized file access. The vulnerability has been assigned a CVSS v3.1 base score of 3.3 (Low) with the vector string CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:L/A:N. The vulnerability is associated with CWE-22 (Path Traversal) and CWE-73 (External Control of File Name or Path) (NVD).

The vulnerability could allow attackers to perform unauthorized file access and potentially access sensitive system files. The impact is considered Low severity due to the high attack complexity and high privileges required for exploitation. The vulnerability affects both confidentiality and integrity with low impact, while availability remains unaffected (Auth0 Advisory).

The vulnerability has been patched in auth0-PHP version 8.17.0. Users are advised to upgrade to this version or later. Additionally, dependent packages have also released patched versions: Auth0/laravel-auth0 (v7.19.0), Auth0/symfony (v5.5.0), and Auth0/wordpress (v5.4.0) (Auth0 Release).
