CVE-2025-3848: CWE-639 Authorization Bypass Through User-Controlled Key in themesgrove Download Manager and Payment Form WordPress Plugin – WP SmartPay
The Download Manager and Payment Form WordPress Plugin – WP SmartPay plugin for WordPress is vulnerable to privilege escalation via account takeover in versions 1.1.0 to 2.7.13. This is due to the plugin not properly validating a user's identity prior to updating their email through the update() function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to change arbitrary user's email addresses, including administrators, and leverage that to reset the user's password and gain access to their account.
AI Analysis
Technical Summary
CVE-2025-3848 is a high-severity vulnerability affecting the Download Manager and Payment Form WordPress Plugin – WP SmartPay, specifically versions 1.1.0 through 2.7.13. The vulnerability stems from improper authorization checks in the plugin's update() function, which handles user email updates. Authenticated users with Subscriber-level privileges or higher can exploit this flaw to change arbitrary users' email addresses, including those of administrators. By altering an administrator's email, the attacker can initiate a password reset process, effectively taking over the administrator account without needing higher privileges initially. This represents an authorization bypass (CWE-639) where user-controlled input is used to manipulate key identity attributes without proper validation. The vulnerability is remotely exploitable over the network (AV:N), requires low attack complexity (AC:L), and only low privileges (PR:L) with no user interaction (UI:N). The impact is severe, affecting confidentiality, integrity, and availability (C:H/I:H/A:H) of the WordPress site, as attackers can gain full administrative control. No known exploits are currently reported in the wild, but the high CVSS score (8.8) indicates a critical risk if weaponized. The plugin is widely used for managing downloads and payment forms, making affected sites vulnerable to account takeover and subsequent malicious activities such as data theft, site defacement, or malware deployment.
Potential Impact
For European organizations using the WP SmartPay plugin, this vulnerability poses significant risks. Compromise of administrator accounts can lead to full site control, enabling attackers to access sensitive customer data, financial information, and internal communications. This can result in data breaches violating GDPR regulations, leading to legal penalties and reputational damage. E-commerce and service providers relying on this plugin for payment processing are particularly at risk of financial fraud and disruption of business operations. Additionally, attackers could use compromised sites to distribute malware or launch further attacks within the organization's network. The ease of exploitation by low-privilege users increases the threat surface, especially in environments where multiple users have Subscriber or Contributor roles. The lack of user interaction requirement facilitates automated attacks, potentially impacting a large number of sites quickly.
Mitigation Recommendations
European organizations should immediately audit their WordPress installations to identify the presence of the WP SmartPay plugin and verify the version in use. If affected versions (1.1.0 to 2.7.13) are detected, organizations must upgrade to the latest patched version as soon as it becomes available from the vendor. In the absence of an official patch, temporary mitigations include restricting plugin access to trusted users only, removing or disabling the plugin, and monitoring logs for suspicious email update requests or password reset attempts. Implementing multi-factor authentication (MFA) for administrator accounts can reduce the risk of account takeover. Additionally, organizations should review user roles and permissions to minimize the number of users with Subscriber-level or higher access. Regular backups and incident response plans should be updated to prepare for potential exploitation. Network-level protections such as web application firewalls (WAFs) can be configured to detect and block anomalous requests targeting the vulnerable update() function.
