CVE-2025-27290 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Erima Zarinpal Donate plugin developed by seyyed-amir, affecting versions up to 1.0. CSRF vulnerabilities occur when a web application does not adequately verify that requests originate from legitimate users, allowing attackers to trick authenticated users into submitting unwanted requests. In this case, the plugin fails to implement proper anti-CSRF protections such as tokens or origin checks, making it possible for attackers to craft malicious web pages or emails that, when visited by an authenticated user, execute unauthorized actions on the donation platform. These actions could include unauthorized donations, modification of donation parameters, or other state-changing operations. The vulnerability is present in the plugin's handling of requests without verifying their legitimacy, which is a common security oversight in web applications. No public exploits have been reported yet, and no official patches are currently linked, indicating that users should be vigilant and monitor for updates. The lack of a CVSS score requires an assessment based on the nature of the vulnerability, which typically has a high impact on integrity and potentially availability, with moderate impact on confidentiality. The vulnerability requires the victim to be authenticated but does not require additional user interaction beyond visiting a malicious site. This makes exploitation feasible in targeted or broad phishing campaigns. The plugin is likely used in WordPress environments focused on donation processing, which are common worldwide but more prevalent in countries with high WordPress adoption and active online donation ecosystems.

The primary impact of CVE-2025-27290 is the potential for unauthorized actions to be performed on behalf of authenticated users without their consent. This can lead to financial losses through unauthorized donations or manipulation of donation settings, undermining trust in the affected organizations. For nonprofits or businesses relying on the Erima Zarinpal Donate plugin, this could disrupt donation workflows, cause reputational damage, and result in financial discrepancies. Additionally, attackers might leverage this vulnerability to perform further attacks by altering configurations or injecting malicious data. Since the vulnerability affects the integrity and availability of donation-related operations, organizations could face operational disruptions. The lack of authentication bypass means attackers need the victim to be logged in, which limits but does not eliminate the scope of exploitation. The absence of known exploits in the wild currently reduces immediate risk but does not preclude future attacks once exploit code becomes available. Organizations worldwide using this plugin or similar donation platforms are at risk, especially those with high volumes of online donations or sensitive financial transactions.

To mitigate CVE-2025-27290, organizations should immediately review the use of the Erima Zarinpal Donate plugin and monitor for official patches or updates from the vendor seyyed-amir. Until a patch is available, administrators should consider disabling or removing the plugin to prevent exploitation. Implementing web application firewalls (WAFs) with rules to detect and block CSRF attack patterns can provide interim protection. Developers and administrators should ensure that all state-changing requests require anti-CSRF tokens and validate the HTTP Referer or Origin headers to confirm legitimate request sources. User education to avoid phishing sites and suspicious links is also important since exploitation requires the victim to be authenticated and visit malicious content. Regularly auditing and monitoring logs for unusual donation activities or configuration changes can help detect exploitation attempts early. Finally, organizations should adopt a defense-in-depth approach by combining secure coding practices, patch management, and network-level protections to reduce risk.
