CVE-2025-13206 is a stored cross-site scripting vulnerability identified in the GiveWP Donation Plugin and Fundraising Platform for WordPress, affecting all versions up to and including 4.13.0. The vulnerability stems from improper neutralization of input during web page generation, specifically inadequate sanitization and escaping of the 'name' parameter. This flaw allows unauthenticated attackers to inject arbitrary JavaScript code into pages that are rendered and viewed by other users. The attack vector requires that avatars be enabled in the WordPress installation, as the vulnerability is tied to the rendering of user names alongside avatars. Once exploited, the malicious script executes in the victim's browser context, potentially compromising user sessions, stealing cookies, or performing actions on behalf of the user. The vulnerability has a CVSS 3.1 base score of 7.2, reflecting its high severity due to network attack vector, no privileges or user interaction required, and a scope change affecting confidentiality and integrity. Although no public exploits have been reported, the vulnerability's characteristics make it a viable target for attackers seeking to compromise donation platforms and their users. The vulnerability is classified under CWE-79, which covers improper neutralization of input leading to cross-site scripting. The lack of a patch at the time of reporting necessitates immediate attention to mitigate risk.

The impact of CVE-2025-13206 is significant for organizations using the GiveWP plugin, particularly those operating donation and fundraising websites. Successful exploitation can lead to the execution of arbitrary scripts in users' browsers, enabling attackers to hijack user sessions, steal sensitive information such as authentication tokens or personal data, and perform unauthorized actions on behalf of users. This undermines the confidentiality and integrity of user data and can damage organizational reputation and trust. Since the vulnerability does not require authentication or user interaction, it can be exploited at scale by remote attackers. The scope change in the CVSS vector indicates that the vulnerability affects components beyond the initially vulnerable plugin, potentially impacting the entire WordPress site environment. For organizations relying on GiveWP for critical fundraising activities, this could disrupt operations and lead to financial and legal repercussions. Additionally, attackers could leverage this vulnerability as a foothold for further attacks within the network or to distribute malware to site visitors.

To mitigate CVE-2025-13206, organizations should prioritize updating the GiveWP plugin to a patched version once it becomes available from the vendor. In the interim, administrators should disable avatars in WordPress installations if feasible, as this is a prerequisite for exploitation. Implementing a Web Application Firewall (WAF) with rules to detect and block malicious input patterns targeting the 'name' parameter can reduce exposure. Site owners should also enforce strict input validation and output encoding on all user-supplied data, particularly in areas rendering user names or comments. Regularly audit and monitor logs for suspicious activity related to the plugin. Educate users and administrators about the risks of XSS and encourage the use of security headers such as Content Security Policy (CSP) to limit script execution. Finally, consider isolating critical donation platforms from other web services to contain potential breaches.
