This exploit involved repeatedly unlocking collateral deposited against short positions on Mirror Protocol.
The lock contract did not contain a duplicate call check for withdrawals, allowing the attacker to drain funds deposited by other users by calling unlock_position_funds for their own position ID multiple times.
On the 14th of May 2022, the vulnerability was finally, and quietly, patched with no mention of the bug nor the $90M loss it had produced just seven months earlier.
