The vulnerability identified as CVE-2025-61080 is a reflected Cross-Site Scripting (XSS) issue in the Clear2Pay Bank Visibility Application - Payment Execution version 1.10.0.104. Reflected XSS occurs when user-supplied input is immediately returned by a web application without proper sanitization or encoding, allowing attackers to inject malicious JavaScript code into the victim's browser session. In this case, the 'ID' parameter in the URL is vulnerable, meaning an attacker can craft a specially designed URL containing malicious script code. When a user clicks this URL, the script executes in their browser with the privileges of the web application, potentially leading to theft of session cookies, redirection to malicious sites, or unauthorized actions performed on behalf of the user. The vulnerability does not require authentication or user privileges beyond clicking a link, making it relatively easy to exploit via phishing or social engineering. Although no public exploits or patches are currently available, the risk remains significant due to the sensitive nature of banking applications and the potential for attackers to leverage this vulnerability to compromise user accounts or escalate attacks within financial institutions. The absence of a CVSS score limits precise severity quantification, but the technical characteristics suggest a high severity level. Clear2Pay is a widely used payment execution platform in the banking sector, and the presence of this vulnerability could undermine trust and security in financial transactions. The vulnerability was reserved in late September 2025 and published in October 2025, indicating recent discovery and disclosure.

For European organizations, particularly banks and financial institutions using Clear2Pay Bank Visibility Application - Payment Execution, this vulnerability could lead to significant security breaches. Exploitation could result in session hijacking, unauthorized transaction initiation, or exposure of sensitive financial data, undermining confidentiality and integrity. The reflected XSS can also facilitate phishing attacks by injecting malicious content into legitimate banking URLs, increasing the risk of credential theft. Given the critical role of payment execution systems, any compromise could disrupt financial operations and damage customer trust. Regulatory compliance risks also arise, as data breaches involving personal financial information may trigger GDPR violations and associated penalties. The impact extends beyond individual institutions to the broader financial ecosystem, potentially affecting interbank transactions and customer confidence across Europe.

To mitigate this vulnerability, organizations should immediately implement strict input validation and output encoding on the 'ID' parameter within the Clear2Pay application to prevent injection of malicious scripts. Employing Content Security Policy (CSP) headers can further reduce the risk by restricting the execution of unauthorized scripts. Regular security testing, including automated scanning and manual penetration testing focused on XSS vectors, should be conducted to identify and remediate similar issues. User education campaigns to raise awareness about phishing and suspicious URLs can reduce the likelihood of successful exploitation. Monitoring web server logs for unusual URL patterns and implementing web application firewalls (WAFs) with rules targeting reflected XSS attacks can provide additional layers of defense. Coordination with Clear2Pay vendors for timely patches or updates is essential once available. Finally, incident response plans should be updated to address potential XSS exploitation scenarios.
