VWE-2017-3415 Viewing Source [template]Vulnerability | cve= | aka= | severity=High | difficulty=Normal | description=CAN-SPAM Non-compliance for subscriptions of threads moved into the wiki. | discover-date=January 26, 2017 | patch-date=February 17, 2017 | patches=4.0.16 Patch Level 1 | workaround=[/template] [H=3]More Details[/h] The unsubscribe URL of subscription emails sent within the past 30 days are no longer valid after the thread is moved. A user wishing to unsubscribe will be unsubscribed from the thread or receive a message that the thread no longer exists. However, the user will continue to receive emails from the new wiki page. This patch changes the behavior so that a thread that is moved into the wiki does not also have its subscriptions moved; any subscribers who wish to keep their subscriptions will need to re-subscribe. For any threads moved prior to the patch, please submit a private support ticket. 912 characters
