CVE-2025-3781 identifies a stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79 in the Raisely Donation Form plugin for WordPress, developed by creativefreedomau. This vulnerability exists in all versions up to and including 1.0 due to improper neutralization of user-supplied input within the raisely_donation_form shortcode. Specifically, the plugin fails to adequately sanitize and escape attributes provided by authenticated users with contributor-level access or higher. As a result, these users can inject arbitrary JavaScript code into pages where the shortcode is used. When other users access these pages, the malicious scripts execute in their browsers, potentially compromising session tokens, redirecting users, or performing unauthorized actions on their behalf. The vulnerability requires authentication at the contributor level, which limits exposure compared to unauthenticated XSS but still poses a significant risk in environments where multiple users have such privileges. The CVSS 3.1 score of 6.4 reflects a medium severity, with network attack vector, low attack complexity, and no user interaction required. The scope is considered changed (S:C) because the vulnerability affects resources beyond the attacker’s privileges, impacting other users. No patches or fixes have been published yet, and no active exploitation has been reported. The vulnerability highlights the importance of proper input validation and output encoding in WordPress plugins, especially those handling user-generated content.

The impact of CVE-2025-3781 can be significant for organizations using the Raisely Donation Form plugin on WordPress sites, particularly those with multiple contributors or editors. Successful exploitation allows an attacker with contributor-level access to inject persistent malicious scripts that execute in the browsers of any user visiting the affected pages. This can lead to session hijacking, theft of sensitive information, unauthorized actions performed on behalf of users, defacement, or distribution of malware. For organizations relying on donation forms, this could erode donor trust, damage reputation, and potentially lead to financial losses. Since the vulnerability requires authenticated access, the risk is higher in environments with less stringent user privilege management or where contributor accounts may be compromised. The medium CVSS score indicates a moderate but non-trivial risk, emphasizing the need for timely mitigation. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as attackers often target WordPress plugins due to their widespread use. Overall, the vulnerability could disrupt normal operations, compromise user data confidentiality and integrity, and impact organizational credibility.

To mitigate CVE-2025-3781 effectively, organizations should implement the following specific measures: 1) Restrict contributor-level access strictly to trusted users and review existing user roles to minimize unnecessary privileges. 2) Employ a Web Application Firewall (WAF) with custom rules to detect and block suspicious input patterns targeting the raisely_donation_form shortcode. 3) Monitor logs and user activity for unusual behavior indicative of attempted XSS injection or privilege misuse. 4) Temporarily disable or remove the Raisely Donation Form plugin if contributor access cannot be sufficiently controlled until a patch is released. 5) Engage with the plugin vendor or community to obtain updates or patches as soon as they become available and apply them promptly. 6) Educate content contributors about secure input practices and the risks of injecting untrusted content. 7) Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on affected pages. 8) Regularly scan the website with security tools specialized in detecting stored XSS vulnerabilities. These targeted actions go beyond generic advice by focusing on access control, monitoring, and layered defenses tailored to the plugin’s context.
