Description Doran Moppert 2019-09-04 00:41:07 UTC 
A same-origin policy violation occurs allowing the theft of cross-origin images through a combination of SVG filters and a `<canvas>` element due to an error in how same-origin policy is applied to cached image content. The resulting same-origin policy violation could allow for data theft.
