Does this matter?

Lower severity and a low EPSS score (3.03%). Track it; it rarely justifies an emergency change on its own.

Description

Manipulating individual parts of a URL object could have caused an out-of-bounds read, leaking process memory to malicious JavaScript. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0.
