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 a web page without proper sanitization or encoding, allowing attackers to execute arbitrary JavaScript in the context of the victim’s browser. In this case, the vulnerability arises from insufficient validation of the 'Name' parameter, which accepts crafted payloads that get stored and subsequently executed when viewed by other users or administrators. The vulnerability requires no authentication privileges (PR:N) but does require user interaction (UI:R) to trigger the malicious script. The attack vector is network-based (AV:N), meaning it can be exploited remotely over the internet. The vulnerability affects confidentiality and integrity by enabling attackers to steal sensitive information such as session cookies, perform actions on behalf of users, or manipulate displayed content. Availability is not impacted. The CVSS 3.1 base score of 6.1 reflects a medium severity, considering the ease of exploitation and the scope of impact. No patches or fixes have been released at the time of publication, and no known exploits have been observed in the wild. The vulnerability is classified under CWE-79, which is a common web application security weakness related to improper neutralization of input. Organizations using Xxl-api v1.3.0 should assess their exposure and implement mitigations promptly to reduce risk.

For European organizations, this vulnerability poses a moderate risk primarily to confidentiality and integrity of web applications using Xxl-api v1.3.0. Exploitation could lead to session hijacking, unauthorized actions, or defacement of web content, potentially damaging organizational reputation and exposing sensitive business information. Since the vulnerability requires user interaction, phishing or social engineering could be used to lure users into triggering the malicious payload. Industries with web-facing management portals, such as finance, manufacturing, and critical infrastructure sectors, may face increased risk. The lack of available patches increases the window of exposure. Additionally, regulatory frameworks like GDPR impose strict requirements on protecting personal data, so exploitation leading to data leakage could result in legal and financial penalties. Organizations relying on Xxl-api for business line management should prioritize vulnerability assessment and remediation to maintain compliance and operational security.

1. Implement strict input validation and output encoding on the 'Name' parameter within the Business Line Management module to prevent injection of malicious scripts. 2. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 3. Conduct regular code reviews and security testing focusing on XSS vulnerabilities, especially in modules handling user input. 4. Educate users and administrators about phishing risks and safe browsing practices to reduce the likelihood of triggering malicious payloads. 5. Monitor web application logs for unusual input patterns or repeated injection attempts targeting the vulnerable parameter. 6. If possible, isolate or restrict access to the affected module to trusted networks until a patch is available. 7. Engage with the vendor or development team to expedite the release of a security patch addressing this vulnerability. 8. Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block XSS payloads targeting the vulnerable parameter.
