JSON

File downloads encoded with “blob:” and “data:” URL elements bypassed
normal file download checks though the Phishing and Malware Protection
feature and its block lists of suspicious sites and files. This would allow
malicious sites to lure users into downloading executables that would
otherwise be detected as suspicious. This vulnerability affects Firefox <
56, Firefox ESR < 52.4, and Thunderbird < 52.4.
