Jump Crypto unveils critical vulnerability on Binance’s BNB Chain

Web3 infrastructure firm Jump Crypto has discovered a vulnerability in the BNB Beacon Chain, which would allow the mint of an unlimited amount of arbitrary tokens. The issue was privately disclosed to the BNB team, enabling a patch to be developed and deployed within 24 hours.

The vulnerability would allow an attacker to mint an almost unlimited amount of BNB tokens via a malicious transfer, meaning that destination accounts would receive a much larger number of BNB tokens than the sender initially provided.
