Overview
Affected versions of this package are vulnerable to Origin Validation Error due to the default CORS settings that set the Access-Control-Allow-Origin: * header. An attacker can intercept and read potentially sensitive information by sending crafted requests from any origin.
Note:
This is only exploitable if the attacker knows the URL of the bundle output file name and if the victim has the source map option enabled.
