Condensed citation of multiple GitHub issues
As hinted in a comment, "the numbers alone would be enough." Those numbers can appear in the main body, e.g., 

During the course of this research, twelve bugs were reported for the  mythril security analysis software. (Those reports are numbered 584, 1270, 1232, 1235, 1293, 1294, 988, 1300, 1303, 1291, 1238, and 1295, all of which are accessibly from the following url: \url{https://github.com/ConsenSys/mythril/issues/}.)

You could push the bracketed details to a footnote, since they are less interesting. You could also summarise any particularly interesting reports, perhaps you've already done that.
