CVE-2025-30639 is a high-severity vulnerability classified under CWE-862 (Missing Authorization) affecting the ThemeAtelier IDonatePro plugin, versions up to 2.1.9. The vulnerability arises from improperly configured access control mechanisms within the plugin, allowing unauthorized users to perform actions or access resources that should be restricted. Specifically, the issue is due to missing authorization checks, meaning that the system does not verify whether a user has the appropriate permissions before granting access to certain functionalities or data. The CVSS v3.1 score of 7.5 reflects a high severity level, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact is primarily on integrity (I:H), with no direct confidentiality (C:N) or availability (A:N) impact noted. This suggests that an attacker can modify or manipulate data or operations within the IDonatePro plugin without authentication, potentially altering donation records, payment processing, or other critical plugin functions. Although no known exploits are currently reported in the wild, the vulnerability's nature and ease of exploitation make it a significant risk. The lack of available patches at the time of publication further increases the urgency for mitigation. The vulnerability affects all installations of IDonatePro up to version 2.1.9, regardless of specific version details, indicating a broad exposure for users of this plugin. Given that IDonatePro is a WordPress plugin commonly used for donation management, the vulnerability could be leveraged to manipulate donation data, disrupt fundraising activities, or undermine trust in organizations relying on this software.

For European organizations, especially nonprofits, charities, and other entities relying on the IDonatePro plugin for managing donations, this vulnerability poses a serious risk. Unauthorized modification of donation data can lead to financial discrepancies, loss of donor trust, and potential legal or regulatory repercussions under data protection laws such as GDPR. The integrity compromise could also facilitate fraudulent transactions or misreporting of funds, damaging organizational reputation. Since the vulnerability does not require authentication or user interaction, attackers can remotely exploit it over the network, increasing the risk of widespread abuse. Additionally, the absence of confidentiality impact means sensitive donor data may not be directly exposed, but the manipulation of donation records alone can have severe operational and financial consequences. The lack of availability impact suggests the plugin or site may remain operational, potentially masking the ongoing exploitation. European organizations with public-facing donation platforms using IDonatePro are particularly vulnerable, as attackers can exploit this flaw without needing insider access or complex attack methods.

Given the absence of an official patch at the time of disclosure, European organizations should implement immediate compensating controls. These include restricting network access to the IDonatePro plugin endpoints via web application firewalls (WAFs) or IP whitelisting to limit exposure to trusted users only. Organizations should audit and monitor logs for unusual activity related to donation management functions, looking for unauthorized changes or access attempts. Temporarily disabling or uninstalling the IDonatePro plugin until a patch is available can prevent exploitation. If disabling is not feasible, organizations should enforce strict role-based access controls at the WordPress level, ensuring only trusted administrators have permissions to manage donations. Regular backups of donation data and plugin configurations should be maintained to enable recovery from unauthorized modifications. Additionally, organizations should stay alert for vendor updates or patches and apply them promptly once released. Engaging with ThemeAtelier support or security advisories can provide early warnings and guidance. Finally, conducting security awareness training for administrators managing the plugin can help detect and respond to suspicious activities quickly.
