CVE-2025-58840 is a stored cross-site scripting vulnerability in the Ibnul H. Custom Team Manager product, affecting versions up to 2.4.2. The issue is caused by improper neutralization of input during web page generation, which allows attackers to inject and store malicious scripts that execute when viewed by other users. The CVSS 3.1 vector indicates network attack vector, low attack complexity, low privileges required, and user interaction needed, with a scope change and limited impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the affected application, potentially leading to information disclosure, session hijacking, or other impacts on user data and application integrity. The CVSS score of 6.5 reflects a medium severity impact with limited confidentiality, integrity, and availability consequences. There are no known exploits in the wild at this time.
