Description Laura Pardo 2019-02-13 18:17:54 UTC
A flaw was found in Firefox version 65. Cross-origin images can be read from a canvas element in violation of the same-origin policy using the transferFromImageBitmap method. 
Note: This only affects Firefox 65. Previous versions are unaffected.

Statement:

In general, this flaw cannot be exploited through email in Thunderbird because scripting is disabled when reading mail, but it is potentially a risk in browser or browser-like contexts.
