CVE-2025-62076 identifies a cross-site scripting (XSS) vulnerability in the Simple Payment plugin developed 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 pages viewed by other users. This type of vulnerability is classified under CWE-79 (Cross-site Scripting), though no specific CWE was listed in the provided data. The CVSS v3.1 base score is 7.1, indicating a high severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L) reveals that the attack can be launched remotely over the network without any privileges, requires low attack complexity, no privileges, but does require user interaction (such as clicking a malicious link). The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. The impact on confidentiality, integrity, and availability is low to moderate, as attackers can steal session tokens, manipulate content, or cause denial of service. No known exploits are currently reported in the wild, but the vulnerability is publicly disclosed and should be considered a significant risk for websites using this plugin. The Simple Payment plugin is commonly used in e-commerce and payment processing scenarios, making the vulnerability particularly sensitive in financial contexts. The lack of patch links suggests that a fix may not yet be publicly available, emphasizing the need for monitoring vendor updates and applying patches promptly once released.

For European organizations, especially those operating e-commerce platforms or online payment systems using the Simple Payment plugin, this vulnerability poses a significant risk. Exploitation can lead to session hijacking, theft of sensitive user data, unauthorized transactions, and defacement or manipulation of payment pages. This can result in financial losses, reputational damage, regulatory penalties under GDPR due to data breaches, and erosion of customer trust. The cross-site scripting vulnerability can also be leveraged as a pivot point for more advanced attacks, including phishing or malware distribution. Organizations with high volumes of online transactions or those in regulated sectors such as finance and retail are particularly vulnerable. The requirement for user interaction means that social engineering or phishing campaigns could be used to increase exploitation success. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as public disclosure often leads to rapid development of exploit code.

1. Monitor the vendor’s official channels for the release of a security patch addressing CVE-2025-62076 and apply it immediately upon availability. 2. Until a patch is available, implement strict input validation and output encoding on all user-supplied data within the Simple Payment plugin context to prevent script injection. 3. Deploy Content Security Policy (CSP) headers configured to restrict the execution of inline scripts and loading of untrusted resources, mitigating the impact of potential XSS payloads. 4. Educate users and staff about the risks of clicking on suspicious links to reduce successful exploitation via social engineering. 5. Conduct regular security audits and penetration testing focusing on web application vulnerabilities, including XSS, especially on payment-related pages. 6. Consider implementing Web Application Firewalls (WAFs) with rules tailored to detect and block XSS attack patterns targeting the Simple Payment plugin. 7. Review and minimize the use of third-party plugins and ensure all components are kept up to date to reduce the attack surface. 8. Log and monitor unusual activities on payment pages to detect potential exploitation attempts early.
