NVD Description

Note: Versions mentioned in the description apply only to the upstream librewolf package and not the librewolf package as distributed by Alpine. See How to fix? for Alpine:3.21 relevant fixed versions and status.

By using a form with a data URI it was possible to gain access to the privileged JSONView object that had been cloned into content. Impact from exposing this object appears to be minimal, however it was a bypass of existing defense in depth mechanisms. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2.
