Name of the Vulnerable Software and Affected Versions @dcl/single-sign-on-client versions prior to 0.1.0

Description The issue concerns improper input validation in the init function, allowing arbitrary JavaScript to be executed using the javascript: prefix. This can be exploited by passing malicious input to the init function, such as SSO.init('javascript:alert("javascript successfully injected")'). There is no information provided about the estimated number of potentially affected devices worldwide or real-world incidents where this issue was exploited.

Recommendations For versions prior to 0.1.0, upgrade to version 0.1.0 to resolve the issue. As a temporary workaround for users unable to upgrade, limit untrusted user input to the init function or ensure that user input is correctly sanitized to prevent exploitation.
