MEDIUM 6.5EPSS 0.64%

Does this matter?

Lower severity and a low EPSS score (0.64%). Track it; it rarely justifies an emergency change on its own.

Description

Due to the Firefox GTK wrapper code's use of text/plain for drag data and GTK treating all text/plain MIMEs containing file URLs as being dragged a website could arbitrarily read a file via a call to `DataTransfer.setData`. This vulnerability affects Firefox < 109, Firefox ESR < 102.7, and Thunderbird < 102.7.
