CVE-2024-53752 is a stored cross-site scripting (XSS) vulnerability identified in the Berg Informatik Stripe Donation plugin, specifically in versions up to 1.2.5. The root cause is improper neutralization of input during web page generation, which allows attackers to inject malicious JavaScript code that is stored persistently within the application. When other users or administrators access the affected pages, the malicious script executes in their browsers, potentially compromising their session cookies, credentials, or enabling further attacks such as phishing or malware distribution. Stored XSS is particularly dangerous because the payload remains on the server and can affect multiple users over time. The vulnerability does not require authentication or complex user interaction, increasing its risk profile. Although no public exploits have been reported yet, the presence of this vulnerability in a widely used donation plugin integrated with Stripe payment services raises concerns about the security of donation platforms and their users. The lack of a CVSS score means severity must be inferred from the nature of the vulnerability, its ease of exploitation, and potential impact. The vulnerability affects all versions up to 1.2.5, and no official patches or mitigation links are currently provided, indicating an urgent need for vendor response or user-applied workarounds.

The impact of CVE-2024-53752 on organizations worldwide can be significant. Stored XSS vulnerabilities can lead to theft of sensitive information such as session tokens, personal data, and payment information, undermining user trust and potentially leading to financial losses. Attackers can also use the vulnerability to perform unauthorized actions on behalf of users, inject malware, or deface websites, damaging organizational reputation. For donation platforms, this could result in donor data compromise and disruption of fundraising activities. The vulnerability affects web applications using the Berg Informatik Stripe Donation plugin, which is likely deployed on WordPress-based e-commerce and charity websites globally. Organizations relying on this plugin without timely remediation expose themselves to targeted attacks that can escalate into broader network compromises. Additionally, regulatory compliance risks arise if personal data is exposed due to exploitation. The absence of known exploits currently provides a window for proactive mitigation but does not reduce the urgency given the vulnerability’s characteristics.

To mitigate CVE-2024-53752, organizations should immediately verify if they are using the Berg Informatik Stripe Donation plugin version 1.2.5 or earlier. If so, they should seek updates or patches from the vendor as a priority. In the absence of official patches, applying web application firewall (WAF) rules to detect and block suspicious input patterns related to script tags or event handlers can reduce risk. Input validation and output encoding should be implemented or enhanced to ensure all user-supplied data is properly sanitized before rendering. Administrators should audit stored content for malicious scripts and remove any suspicious entries. Additionally, limiting user privileges to trusted users only and monitoring logs for unusual activity can help detect exploitation attempts. Employing Content Security Policy (CSP) headers to restrict script execution sources can further mitigate impact. Regular security assessments and penetration testing focused on XSS vulnerabilities are recommended to identify and remediate similar issues proactively.
