CVE-2025-60131 is a Stored Cross-Site Scripting (XSS) vulnerability identified in the Zoefff product Werk aan de Muur, a platform presumably used for art or creative content sharing. The vulnerability stems from improper neutralization of input during web page generation, allowing malicious scripts to be stored and later executed in the browsers of users viewing the affected pages. This type of vulnerability can lead to unauthorized actions such as session hijacking, defacement, or data theft. The CVSS 3.1 score of 5.5 reflects a medium severity, with an attack vector of network (remote exploitation), high attack complexity, and requiring high privileges, but no user interaction. The scope is changed, indicating that the vulnerability affects components beyond the initially vulnerable module. The impact on confidentiality, integrity, and availability is low but present. No patches or known exploits are currently reported, suggesting the vulnerability is newly disclosed. The lack of user interaction reduces the attack surface, but the requirement for high privileges means attackers must already have significant access to exploit this flaw. The vulnerability affects all versions up to and including 1.5 of Werk aan de Muur. Given the nature of stored XSS, attackers could leverage this to compromise user sessions or inject malicious content, potentially impacting users and administrators of the platform.

For European organizations using Werk aan de Muur, this vulnerability could lead to unauthorized script execution within user browsers, resulting in session hijacking, credential theft, or unauthorized actions performed on behalf of legitimate users. Although exploitation requires high privileges, an attacker who gains such access could leverage this vulnerability to escalate their control or pivot within the network. The impact on confidentiality is limited but real, as sensitive user data could be exposed. Integrity could be compromised through unauthorized content manipulation, and availability might be affected if malicious scripts disrupt normal platform operations. Organizations in sectors relying on this platform for creative or artistic collaboration could face reputational damage and operational disruption. The absence of known exploits reduces immediate risk, but the presence of stored XSS vulnerabilities historically correlates with targeted attacks, especially in environments with valuable user-generated content.

Organizations should monitor for official patches from Zoefff and apply them promptly once available. In the interim, implement strict input validation and output encoding on all user-supplied data to prevent script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Limit user privileges rigorously to reduce the risk of high-privilege attackers exploiting this vulnerability. Conduct regular security audits and penetration testing focused on input handling and stored XSS vectors. Educate administrators and users about the risks of XSS and encourage the use of multi-factor authentication to mitigate session hijacking risks. Additionally, consider deploying web application firewalls (WAFs) with rules tuned to detect and block XSS payloads targeting this platform. Logging and monitoring for unusual activity related to script injection attempts should be enhanced to enable early detection.
