Name of the Vulnerable Software and Affected Versions Live Helper Chat versions prior to 3.44v

Description The issue allows for stored XSS in chat messages with an operator via BBCode. This means that an attacker can inject malicious code into chat messages, which can then be executed by the operator's browser, potentially leading to unauthorized access or other malicious activities.

Recommendations For versions prior to 3.44v, update to version 3.44v or later to resolve the issue. As a temporary workaround, consider disabling the use of BBCode in chat messages until a patch is available. Restrict access to chat messages with operators to minimize the risk of exploitation.
