Is SocialBook - YouTube Builder safe?

Low risk

SocialBook - YouTube Builder lets embedding pages request a canvas capture of the current YouTube video frame.

SocialBook - YouTube Builder runs a content script inside YouTube frames and listens for ScreenCapRequest messages without checking the sender's origin. When it receives one, it draws the current YouTube video frame to a canvas and returns the resulting data URL image to the requesting page.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.
