Summary
AdaptiveGRC is vulnerable to Stored XSS via text type fields across the forms. Authenticated attacker can replace the value of the text field in the HTTP POST request. Improper parameter validation by the server results in arbitrary JavaScript execution in the victim's browser. Critically, this may allow the attacker to obtain the administrator authentication token and perform arbitrary actions with administrative privileges, which could lead to further compromise.
This issue occurs in versions released before December 2025.
