Name of the Vulnerable Software and Affected Versions
Firefox versions prior to 66
Description
The issue is related to the
createImageBitmap function, which can be used to read cross-origin images in violation of the same-origin policy. This can be achieved by exporting an image after using createImageBitmap to read the image and then rendering the resulting bitmap image within a canvas element. The exploitation of this issue may allow a remote attacker to disclose protected information.Recommendations
For Firefox versions prior to 66, update to version 66 or later to resolve the issue. As a temporary workaround, consider restricting the use of the
createImageBitmap function until a patch is available.Exploit
