Reported as exploited in the wild as part of Google’s 2020 0day vulnerability spreadsheet they made available at https://docs.google.com/spreadsheets/d/1lkNJ0uQwbeC1ZTRrxdtuPLCIl7mlUreoKfSIgajnSyY/edit#gid=1869060786. Original tweet announcing this spreadsheet with the 2020 findings can be found at https://twitter.com/maddiestone/status/1329837665378725888

This is pretty similar to CVE-2020-1020 and its possible they were used together in a single attack, although for now this is just my theory and without full evidence this should be taken with a healthy few grains of salt.
