Reaching this weakness in Embed Plus for YouTube Gallery, Livestream and Lazy Loading with Facades <= 11.8.1 takes a caller who can reach the endpoint.

For Embed Plus for YouTube Gallery, Livestream and Lazy Loading with Facades the fix is 11.8.2: builds <= 11.8.1 are affected, anything from 11.8.2 onward is not.
