ECHO-1B2E-BA53-A2B7 CVE-2020-27748 is fully addressed by the CVE-2022-4055 fix (already applied). The vulnerability existed in the run_thunderbird() function which parsed attach= parameters from mailto URIs. The CVE-2022-4055 patch (MR #58) completely removed run_thunderbird(), all Thunderbird detection/dispatch code, and the --attach CLI option. Since the entire vulnerable code surface has been deleted, CVE-2020-27748 cannot be exploited.
