Ledger identified and patched a transaction replacement vulnerability caused by a race condition in their Ethereum app 1.22.1, with no reported user impact. The fix was deployed in version 1.22.2 as confirmed by their security team.

This Wire brief sits within Fusion42's coverage of Crypto & Web3 and Cybersecurity.

◆ ◆ The Wire takeaway

You must push your customers to update stuck wallet apps immediately because outdated crypto wallets remain vulnerable even if the issue is fixed upstream. Stale software is your quickest route to exploitation.
