CVE-2025-57930 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the kanwei_doublethedonation product called Double the Donation, affecting versions up to 2.0.0. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a malicious request to a web application in which they are currently authenticated, without their consent or knowledge. This can lead to unauthorized actions being performed on behalf of the user. In this case, the vulnerability allows an attacker to craft a request that, when executed by an authenticated user, could alter some state or perform actions within the Double the Donation application. The CVSS v3.1 base score of 4.3 (medium severity) reflects that the attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R), and impacts integrity (I:L) but not confidentiality or availability. The scope remains unchanged (S:U). No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is categorized under CWE-352, which specifically relates to CSRF issues. Since Double the Donation is a tool used primarily for managing donation matching and fundraising activities, unauthorized changes could disrupt donation processing or data integrity, potentially impacting organizational fundraising operations.

For European organizations, especially non-profits, charities, and fundraising entities using Double the Donation, this vulnerability could lead to unauthorized manipulation of donation matching data or settings. While it does not directly compromise confidentiality or availability, the integrity impact could result in incorrect donation records, financial discrepancies, or reputational damage if donors perceive mishandling of funds. Given the nature of the product, attackers could potentially cause financial misallocations or disrupt fundraising campaigns. The requirement for user interaction means phishing or social engineering could be used to exploit this vulnerability. Organizations handling sensitive donor information or large volumes of donations could face regulatory scrutiny under GDPR if data integrity is compromised. The medium severity indicates a moderate risk but should not be ignored, especially in environments where donation accuracy is critical.

To mitigate this CSRF vulnerability, organizations should implement anti-CSRF tokens in all state-changing requests within the Double the Donation application. This includes ensuring that any form submissions or AJAX requests that modify data require a unique, unpredictable token that is validated server-side. Additionally, enforcing the SameSite cookie attribute (preferably 'Strict' or 'Lax') can reduce the risk of CSRF by restricting cross-origin requests. Organizations should also educate users about phishing and social engineering risks to reduce the likelihood of user interaction exploitation. Monitoring and logging unusual or unexpected changes in donation data can help detect exploitation attempts. Since no official patches are currently available, organizations should consider isolating or restricting access to the affected application where possible, and apply web application firewalls (WAFs) with rules to detect and block CSRF attack patterns. Regularly checking for vendor updates or patches is critical to apply fixes once released.
