Does this matter?

Lower severity and a low EPSS score (0.91%). Track it; it rarely justifies an emergency change on its own.

A malicious installed WebExtension could open arbitrary URLs, which under the right circumstance could be leveraged to collect sensitive user data. This vulnerability affects Firefox < 119, Firefox ESR < 115.4, and Thunderbird < 115.4.1.
