Zcash fixes critical node vulnerability, preventing potential $6.5M hack

A critical security vulnerability has been fixed in Zcash nodes that could have allowed attackers to bypass proof verification for the older 'Sprout' anonymous pool, Decrypt reported. The Zcash development team released an emergency patch, version v6.12.0, last Tuesday to address the issue. Had a malicious miner exploited the flaw, they could have stolen 25,424 ZEC, worth approximately $6.5 million, remaining in the Sprout pool. No actual attacks occurred.
