When DNS over HTTPS is in use, it intentionally filters RFC1918 and related IP ranges from the responses as these do not make sense coming from a DoH resolver. However when an IPv4 address was mapped through IPv6, these addresses were erroneously let through, leading to a potential DNS Rebinding attack. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
Data is provided by the National Vulnerability Database (NVD)
Mozilla ≫ Firefox ESR Version < 78.5
Mozilla ≫ Thunderbird Version < 78.5
