MEDIUM 4.3EPSS 0.85%
Does this matter?
Lower severity and a low EPSS score (0.85%). Track it; it rarely justifies an emergency change on its own.
Description
Repeated calls to the history and location interfaces could have been used to hang the browser. This was addressed by introducing rate-limiting to these API calls. This vulnerability affects Firefox < 83.
