What is CVE-2025-61949?

LogStare Collector contains a vulnerability that allows stored cross-site scripting (XSS) through manipulated user information within the UserManagement module. When crafted payloads are stored, they may lead to arbitrary script execution in the browsers of users accessing the management portal. This raises significant security concerns, potentially compromising session data and user privacy. Proper validation and sanitization of user inputs are essential to mitigate this risk.
