CVE-2025-67583 identifies a missing authorization vulnerability in the ThemeAtelier IDonate plugin, a WordPress plugin designed to facilitate donation management. The flaw stems from incorrectly configured access control security levels, which means that certain actions or endpoints within the plugin do not properly verify whether the user has the necessary permissions before allowing access or execution. This can enable unauthorized users, including unauthenticated attackers or low-privileged users, to perform restricted operations such as modifying donation data, viewing sensitive information, or manipulating donation workflows. The affected versions include all versions up to and including 2.1.15, with no specific version range provided. No public exploits have been reported yet, and no official patch links are available at the time of publication. The vulnerability was published on December 9, 2025, and is tracked under CVE-2025-67583. The absence of a CVSS score indicates that the vulnerability has not yet been fully assessed for impact severity, but the nature of missing authorization typically represents a significant security risk. The vulnerability is particularly relevant for organizations relying on IDonate for managing donations, as unauthorized access could lead to data breaches, fraudulent transactions, or disruption of fundraising activities.

For European organizations, especially nonprofits, charities, and other entities relying on online donation platforms, this vulnerability poses a significant risk. Unauthorized access could lead to exposure or manipulation of donor information, financial data, and donation records, potentially resulting in financial loss, reputational damage, and regulatory non-compliance (e.g., GDPR violations). The disruption of donation processes could impair fundraising efforts and trust with donors. Since IDonate is a WordPress plugin, any organization using WordPress for their donation management is potentially affected. The impact is heightened in countries with a strong nonprofit sector and high WordPress adoption, where online donations are a critical revenue stream. Additionally, the lack of authentication requirements for exploiting this vulnerability increases the attack surface, making it easier for attackers to leverage the flaw remotely without user interaction. This could facilitate automated attacks or exploitation by opportunistic threat actors.

Organizations should immediately review their use of the IDonate plugin and restrict access to donation management interfaces to trusted users only. Until an official patch is released, administrators can implement the following mitigations: 1) Restrict access to plugin-related endpoints via web application firewalls (WAF) or server-level access controls (e.g., IP whitelisting). 2) Harden WordPress user roles and permissions to ensure only authorized personnel have administrative or donation management privileges. 3) Monitor logs for unusual access patterns or unauthorized attempts to access donation-related functionality. 4) Disable or remove the IDonate plugin if it is not essential or if a secure alternative exists. 5) Stay informed about updates from ThemeAtelier and apply patches promptly once available. 6) Conduct regular security audits and penetration testing focused on access control mechanisms within WordPress plugins. These steps go beyond generic advice by focusing on access control hardening and proactive monitoring specific to this plugin's context.
