CVE-2022-28282
By using a link with <code>rel="localization"</code> a use-after-free could have been triggered by destroying an object during JavaScript execution and then referencing the object through a freed pointer, leading to a potential exploitable crash.
Does this matter?
Lower severity and a low EPSS score (2.01%). Track it; it rarely justifies an emergency change on its own.
