Leaking of user information on Cross-Domain communication in sysend
Impact
Users that use Cross-Origin communication and send sensitive information make it possible for this data to be intercepted. This is not a big impact because it happens only on the same browser.
Patches
It has been patched in version 1.10.0
Workarounds
The only workaround is to not send sensitive information with sysend messages.
