Storing Passwords in a Recoverable Format in pimcore/customer-data-framework

Vulnerability

Overview The CVE-2023-2881 vulnerability in the Pimcore Customer Data Framework (CDF) arises from storing passwords in a recoverable format[1][2]. Specifically, the customer detail view disclosed the password hash for users, as noted in the advisory[4]. The fix commit (d1d58c1) removes the password field from the customer details view, preventing its exposure[3]. The root cause is that the password field was marked as visible in the detail view configuration, contrary to security best practices.

Exploitation

Prerequisites An attacker with authenticated access to the Pimcore backend, specifically with permissions to view customer detail data, could exploit this vulnerability. The exposed password hash could be retrieved through the normal UI or API endpoints that render customer data. No special network position or elevated privileges beyond standard backend access are required, as the password hash was part of the default view data for customers[4].

Impact

An attacker who obtains the password hash can attempt offline brute-force or dictionary attacks to recover the plaintext password. If successful, this could lead to unauthorized access to customer accounts, data breaches, and further compromise of the Pimcore system. The vulnerability is rated with a CVSS severity reflecting the serious confidentiality impact of password exposure[2].

Mitigation and

Remediation The vulnerability is patched in version 3.3.10 of the Customer Data Framework[2][3]. Users are strongly advised to update to this version or later. Note that the affected repository is archived as of April 2026, and the GPL version is End-of-Life (EOL)[1]. For continued support, users should migrate to the Pimcore Enterprise Edition's ee-customer-data-framework or obtain LTS support through the Pimcore support portal[1]. No workaround is available; updating is the only recommended course of action.
