Name of the Vulnerable Software and Affected Versions MrSwitch hello.js versions 1.18.6 through 1.18.7

There is no information about real-world incidents where this issue was exploited.

Recommendations For MrSwitch hello.js versions 1.18.6 through 1.18.7, update to version 1.18.8 or later to resolve the issue. As a temporary workaround, consider disabling the hello.utils.extend function until a patch is available. Restrict access to the hello.utils.extend function to minimize the risk of exploitation.
