CVE-2025-60646 is a stored cross-site scripting (XSS) vulnerability identified in the Business Line Management module of Xxl-api version 1.3.0. Stored XSS occurs when malicious input is saved by the application and later rendered in web pages without proper sanitization or encoding, allowing attackers to execute arbitrary JavaScript in the context of other users' browsers. In this case, the vulnerability arises from insufficient validation or sanitization of the 'Name' parameter, which accepts crafted payloads that can include malicious scripts or HTML. When a victim accesses the affected page, the injected script executes, potentially enabling attackers to steal session cookies, perform actions on behalf of the user, deface the website, or redirect users to malicious sites. The vulnerability does not require prior authentication or user interaction beyond visiting the affected page, increasing its risk. Although no known exploits have been reported in the wild, the vulnerability is publicly disclosed and thus may attract attackers. No official patch or CVSS score has been published yet, but the impact on confidentiality, integrity, and availability can be significant in environments where sensitive data or critical functions are exposed. The vulnerability affects organizations using Xxl-api v1.3.0, particularly those relying on the Business Line Management module for operational workflows. Given the nature of stored XSS and its persistence, attackers can maintain long-term access or influence over compromised user sessions. This vulnerability highlights the importance of secure coding practices, including input validation, output encoding, and content security policies to mitigate XSS risks.

For European organizations, exploitation of CVE-2025-60646 could lead to unauthorized access to user sessions, data theft, and manipulation of business management interfaces. This can compromise sensitive business information, disrupt operations, and damage organizational reputation. In sectors such as finance, healthcare, and critical infrastructure, the impact could extend to regulatory non-compliance and financial losses. The persistent nature of stored XSS means that multiple users can be affected over time, increasing the scope of potential damage. Additionally, attackers could use the vulnerability as a foothold for further attacks within the network or to spread malware. Given the lack of authentication requirements and ease of exploitation, the threat is significant for any European entity using the vulnerable software. The absence of a patch increases the urgency for interim mitigations to protect against exploitation.

1. Immediately implement strict input validation on the 'Name' parameter to reject or sanitize any HTML or script content before storage. 2. Apply output encoding/escaping on all user-supplied data when rendering in web pages to prevent script execution. 3. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 4. Monitor web application logs for suspicious input patterns or repeated injection attempts. 5. Restrict access to the Business Line Management module to trusted users and networks until a patch is available. 6. Engage with the vendor or development team to obtain or expedite a security patch for Xxl-api v1.3.0. 7. Conduct security awareness training for users to recognize and report unusual behavior or phishing attempts that may leverage this vulnerability. 8. Consider implementing web application firewalls (WAF) with rules to detect and block XSS payloads targeting the vulnerable parameter. 9. Regularly review and update software components to ensure timely application of security fixes.
