TechFlow reports that on October 27, Casey, the founder of Ordinals, issued a warning on X, urging users to upgrade their ord wallets to version 0.21.2 as soon as possible. This update fixes a critical vulnerability that could lead to accidental loss of runes when using the "ord wallet send" function, due to incorrect creation of change outputs. Casey explained that when an input UTXO contains multiple runes (A and B), sending rune A might inadvertently cause rune B to be sent as well. The update also adds message signing functionality for wallet addresses and resolves an issue with minting progress display. No user asset losses related to this vulnerability have been reported so far.
