CVE-2025-67583 identifies a missing authorization vulnerability in the ThemeAtelier IDonate plugin, affecting versions up to and including 2.1.15. This vulnerability arises from incorrectly configured access control security levels, allowing unauthenticated remote attackers to bypass authorization checks. The exploit does not require user interaction or prior authentication, making it accessible over the network. The vulnerability impacts confidentiality by potentially exposing sensitive information or functionalities that should be restricted, but it does not affect data integrity or system availability. The CVSS 3.1 base score is 5.3 (medium), reflecting the ease of exploitation (network vector, low attack complexity, no privileges required) but limited impact scope (confidentiality only, no integrity or availability impact). No known exploits have been reported in the wild, and no official patches have been released at the time of publication. The vulnerability is relevant to organizations using the IDonate plugin for managing donations or fundraising activities, which may involve sensitive donor information or financial data. The root cause is a failure to enforce proper authorization checks on certain plugin functionalities, potentially allowing unauthorized access to restricted operations or data. This type of vulnerability can lead to information disclosure or unauthorized data access, undermining trust and compliance with data protection regulations.

For European organizations, the primary impact of CVE-2025-67583 is unauthorized access to sensitive donation-related data or functionalities within the IDonate plugin. This could lead to exposure of donor information, fundraising details, or other confidential data, potentially violating GDPR and other privacy regulations. Although the vulnerability does not allow data modification or service disruption, the confidentiality breach alone can damage organizational reputation and result in regulatory penalties. Non-profits, charities, and other entities relying on IDonate for fundraising are particularly at risk. The ease of exploitation without authentication increases the threat level, as attackers can probe for vulnerable instances remotely. The absence of known exploits in the wild reduces immediate risk but does not eliminate the potential for future attacks. Organizations may also face indirect impacts such as loss of donor trust and increased scrutiny from regulators. Given the widespread use of WordPress and associated plugins in Europe, the vulnerability could affect a significant number of sites if not addressed promptly.

1. Immediately audit all instances of the IDonate plugin to identify affected versions (up to 2.1.15) and prioritize their remediation. 2. Restrict access to the plugin’s administrative and sensitive functionalities using web application firewalls (WAFs) or IP whitelisting to limit exposure to unauthorized users. 3. Monitor web server and application logs for unusual access patterns or attempts to exploit access control weaknesses. 4. Engage with ThemeAtelier or official plugin channels to obtain and apply patches or updates as soon as they become available. 5. If patches are delayed, consider temporarily disabling the plugin or replacing it with alternative donation management solutions that have verified secure access controls. 6. Implement strict role-based access controls (RBAC) within WordPress to minimize permissions granted to users and plugins. 7. Conduct regular security assessments and penetration tests focusing on access control mechanisms in critical plugins. 8. Educate site administrators about the risks of missing authorization vulnerabilities and the importance of timely updates and monitoring.
