CVE-2025-62076 identifies a cross-site scripting (XSS) vulnerability in the Simple Payment plugin by Ido Kobelkowsky, affecting all versions up to and including 2.4.6. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows attackers to inject malicious JavaScript code into the application’s output. This type of vulnerability is classified as reflected or stored XSS depending on how the input is handled, but the details suggest it occurs during page generation, likely enabling attackers to craft URLs or input fields that execute scripts in the context of the victim’s browser. The CVSS 3.1 score of 7.1 indicates a high severity, with an attack vector of network (remote), low attack complexity, no privileges required, but user interaction needed (e.g., victim clicking a malicious link). The scope is changed, meaning the vulnerability can affect resources beyond the initially vulnerable component. The impact includes partial loss of confidentiality (e.g., theft of cookies or credentials), integrity (e.g., unauthorized actions performed on behalf of the user), and availability (e.g., disruption of service via script-based attacks). Although no known exploits are reported in the wild, the vulnerability is publicly disclosed and should be considered a significant risk. The Simple Payment plugin is commonly used in e-commerce environments to facilitate online transactions, making it a valuable target for attackers aiming to steal payment data or disrupt services. The lack of a patch link indicates that a fix may not yet be available, emphasizing the need for immediate mitigation steps.

For European organizations, especially those in e-commerce, retail, and financial services, this vulnerability poses a substantial risk. Exploitation can lead to theft of sensitive customer data, including payment information, resulting in financial loss and reputational damage. The partial compromise of integrity could allow attackers to manipulate transaction data or perform unauthorized actions, undermining trust in payment systems. Availability impacts could disrupt online payment processing, causing operational downtime and customer dissatisfaction. Given the interconnected nature of European markets and strict data protection regulations like GDPR, exploitation could also lead to regulatory penalties and legal consequences. Organizations relying on the Simple Payment plugin must consider the potential for targeted attacks aiming to exploit this vulnerability to gain footholds in their systems or exfiltrate data.

1. Monitor vendor communications closely for official patches or updates addressing CVE-2025-62076 and apply them immediately upon release. 2. Until a patch is available, implement Web Application Firewall (WAF) rules to detect and block common XSS attack patterns targeting the Simple Payment plugin. 3. Conduct thorough input validation and output encoding on all user-supplied data within the payment application to prevent script injection. 4. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 5. Educate users and staff about the risks of clicking on suspicious links or interacting with untrusted content related to payment systems. 6. Perform regular security assessments and penetration testing focusing on web application vulnerabilities, including XSS. 7. Consider isolating or sandboxing the payment plugin environment to limit the impact of potential exploitation. 8. Review and enhance logging and monitoring to detect anomalous activities indicative of exploitation attempts.
