CVE-2025-60157 is a Stored Cross-site Scripting (XSS) vulnerability classified under CWE-79, affecting the emarket-design WP Ticket Customer Service Software & Support Ticket System up to version 6.0.2. This vulnerability arises due to improper neutralization of user-supplied input during web page generation, allowing malicious scripts to be stored and later executed in the context of users viewing the affected pages. The vulnerability requires low privileges (PR:L) and user interaction (UI:R) to be exploited, but can be triggered remotely (AV:N). The scope is changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component. The CVSS v3.1 base score is 6.5, reflecting a medium severity level with partial impact on confidentiality, integrity, and availability. Specifically, an attacker can inject malicious JavaScript payloads into ticket system pages, which when viewed by other users or administrators, can lead to session hijacking, credential theft, or unauthorized actions performed with the victim’s privileges. The vulnerability does not currently have known exploits in the wild, and no official patches have been linked yet. However, given the nature of stored XSS in customer service platforms, the risk of phishing, privilege escalation, and data leakage is significant if exploited. The vulnerability affects all versions up to 6.0.2, with no specific earliest affected version stated. The WP Ticket system is a WordPress plugin widely used to manage customer support tickets, making it a valuable target for attackers seeking to compromise support workflows or gain footholds in organizational networks.

For European organizations, this vulnerability poses a risk to the confidentiality and integrity of customer support communications and potentially broader internal systems if attackers leverage the XSS to escalate privileges or move laterally. Customer service platforms often handle sensitive personal data and internal operational details, so exploitation could lead to data breaches under GDPR regulations, resulting in legal and financial penalties. The stored nature of the XSS means that multiple users, including support staff and customers, could be affected, amplifying the impact. Additionally, attackers could use the vulnerability to implant persistent malicious scripts that facilitate further attacks such as credential theft or deployment of malware. Given the interconnected nature of enterprise IT environments in Europe, a successful attack could disrupt customer service operations and damage organizational reputation. The medium severity score suggests that while the vulnerability is serious, exploitation requires some user interaction and privileges, somewhat limiting the attack surface but not eliminating risk.

European organizations using the WP Ticket Customer Service Software should immediately audit their installations for the affected versions and plan for an upgrade once a patch is released. In the interim, they should implement strict input validation and output encoding on all user-supplied data fields within the ticket system to neutralize potentially malicious scripts. Deploying Web Application Firewalls (WAFs) with custom rules to detect and block typical XSS payloads targeting the ticket system can reduce risk. Organizations should also enforce the principle of least privilege for users interacting with the ticket system to limit the potential damage of an exploit. Regular security awareness training for support staff to recognize suspicious inputs or behaviors can help mitigate social engineering attempts leveraging this vulnerability. Monitoring logs for unusual activity related to the ticket system and isolating the system from critical internal networks can further reduce impact. Finally, organizations should subscribe to vendor advisories and CVE databases to promptly apply official patches once available.
