CVE-2025-49413 is a medium-severity vulnerability classified under CWE-79, which corresponds to Improper Neutralization of Input During Web Page Generation, commonly known as Cross-site Scripting (XSS). This vulnerability affects the Wishloop Terms of Service & Privacy Policy Generator product, specifically versions up to 1.0. The flaw allows an attacker to inject malicious scripts that are stored persistently within the application, leading to Stored XSS attacks. Stored XSS occurs when malicious input is saved by the application and later rendered in users' browsers without proper sanitization or encoding, enabling execution of arbitrary JavaScript code. According to the CVSS 3.1 vector (AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:L), the attack can be performed remotely over the network with low attack complexity but requires high privileges and user interaction. The scope is changed, indicating that the vulnerability affects resources beyond the initially vulnerable component. The impact includes limited confidentiality, integrity, and availability losses, as the attacker can execute scripts that may steal session tokens, manipulate page content, or perform actions on behalf of the user. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability was reserved in June 2025 and published in August 2025. The affected product is a web-based tool used to generate legal documents such as Terms of Service and Privacy Policies, which are often embedded into websites or applications. Stored XSS in such a tool could allow attackers to compromise the security of websites using generated content, potentially affecting end users and administrators who interact with these documents.

For European organizations, the impact of this vulnerability can be significant, particularly for those relying on the Wishloop Terms of Service & Privacy Policy Generator to create legal documents embedded in their websites or applications. Exploitation could lead to session hijacking, defacement, or unauthorized actions performed in the context of authenticated users, including administrators. This can result in data leakage, reputational damage, and potential non-compliance with data protection regulations such as GDPR if personal data is exposed or manipulated. Since the vulnerability requires high privileges and user interaction, the risk is somewhat mitigated but still relevant in environments where privileged users access the affected system. The scope change indicates that the vulnerability could affect multiple components or services, increasing the potential attack surface. European organizations in sectors with high regulatory scrutiny (e.g., finance, healthcare, e-commerce) may face increased risks due to the sensitivity of data and the importance of maintaining trust and compliance.

1. Implement strict input validation and output encoding: Ensure that all user-supplied input is properly sanitized and encoded before rendering in web pages to prevent script injection. 2. Apply Content Security Policy (CSP): Deploy CSP headers to restrict the execution of untrusted scripts and reduce the impact of XSS attacks. 3. Limit privileges: Restrict access to the Wishloop generator tool to only necessary users with minimal privileges to reduce the risk of exploitation. 4. Monitor and audit usage: Regularly review logs and user activities for suspicious behavior that may indicate attempted exploitation. 5. Isolate generated content: Where possible, serve generated Terms of Service and Privacy Policies from separate domains or sandboxed environments to limit script execution impact. 6. Stay updated: Monitor Wishloop vendor communications for patches or updates addressing this vulnerability and apply them promptly once available. 7. Educate users: Train privileged users on the risks of XSS and the importance of cautious interaction with generated content and input fields.
