CVE-2025-58769 is a path traversal vulnerability identified in the Auth0-PHP SDK, specifically affecting versions 3.3.0 through 8.16.0. This SDK is widely used for integrating Auth0 Authentication and Management APIs into PHP applications, including popular frameworks such as Laravel (laravel-auth0), Symfony, and WordPress. The vulnerability resides in the Bulk User Import endpoint, where the SDK fails to properly validate the file-path wrapper or the file path value provided by the user. This improper validation allows an attacker to supply arbitrary file paths or URLs, potentially enabling unauthorized access to files outside the intended restricted directories. The underlying weakness corresponds to CWE-22 (Improper Limitation of a Pathname to a Restricted Directory) and CWE-73 (External Control of File Name or Path). Although the vulnerability does not require user interaction, it does require high privileges (PR:H) to exploit, and the attack complexity is high (AC:H). The CVSS v3.1 base score is 3.3, indicating a low severity level, with limited impact on confidentiality and integrity and no impact on availability. The issue is resolved in version 8.17.0 of the SDK. No known exploits have been reported in the wild as of the publication date (October 1, 2025).

For European organizations, the impact of this vulnerability depends largely on the extent to which they use the affected Auth0-PHP SDK versions within their PHP applications, particularly those leveraging Laravel, Symfony, or WordPress frameworks. Exploitation could allow attackers with elevated privileges to access or manipulate files outside the intended directories, potentially leading to unauthorized disclosure or modification of sensitive data. While the vulnerability does not directly lead to system compromise or denial of service, unauthorized file access could facilitate further attacks or data leakage. Organizations handling sensitive personal data, such as those in finance, healthcare, or government sectors, could face regulatory and reputational risks if such data is exposed. However, the requirement for high privileges to exploit this vulnerability limits the attack surface, reducing the likelihood of widespread impact. The absence of known exploits in the wild further mitigates immediate risk but does not eliminate the need for remediation.

European organizations should prioritize upgrading the Auth0-PHP SDK to version 8.17.0 or later, where the vulnerability is fixed. For applications indirectly using the affected SDK through Auth0/symfony, Auth0/laravel-auth0, or Auth0/wordpress SDKs, ensure these dependencies are also updated accordingly. Additionally, organizations should audit their applications to verify that file path inputs, especially those related to bulk user imports or file handling, are properly validated and sanitized to prevent path traversal attacks. Implementing strict access controls and limiting the privileges of accounts that can perform bulk imports will reduce the risk of exploitation. Monitoring and logging file access activities related to the Bulk User Import endpoint can help detect suspicious behavior. Finally, conducting regular security assessments and code reviews focusing on file handling logic will help identify and remediate similar vulnerabilities proactively.
