Zcash has addressed a critical security vulnerability in its node software, which affected the deprecated Sprout privacy pool. This flaw could have theoretically allowed malicious miners to steal approximately 25,000 ZEC, valued at around $6.5 million at current prices. The development team released version 6.12.0 to fix the issue, and major mining pools completed the upgrade within three days. Officials confirmed that the vulnerability was not exploited, ensuring user funds remain secure.
