CVE-2019-11743 is fixed in 11 products on 2 platforms, first by firefox 69.0+build2-0ubuntu0.18.04.1, released September 3, 2019. It is not reported as exploited. Patch Radar priority: Routine.
Navigation events were not fully adhering to the W3C's "Navigation-Timing Level 2" draft specification in some instances for the unload event, which restricts access to detailed timing attributes to only be same-origin. This resulted in potential cross-origin information exposure of history through timing side-channel attacks. This vulnerability affects Firefox < 69, Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR < 60.9, and Firefox ESR < 68.1.
