Summary
A cross-site scripting (XSS) vulnerability was found in Privoce Vocechat up to version 0.9.121, in the widget.html file's handling of the 'welcome' query parameter. Manipulation of this argument allows execution of malicious script. The attack can be launched remotely, and the exploit has been publicly disclosed.
Risk Assessment
This XSS vulnerability may allow an attacker to execute arbitrary JavaScript in the user's browser, potentially leading to session theft, account takeover, or content modification. Due to the public exploit, the risk is elevated.
