This vulnerability affects Firefox < 66.

MEDIUM 5.3EPSS 1.11%

Does this matter?

Lower severity and a low EPSS score (1.11%). Track it; it rarely justifies an emergency change on its own.

Description

Cross-origin images can be read in violation of the same-origin policy by exporting an image after using createImageBitmap to read the image and then rendering the resulting bitmap image within a canvas element. This vulnerability affects Firefox < 66.
