Zcash has announced the release of zcashd v6.12.1, alongside the Zcash Foundation's release of Zebra v4.3.1, to address four security vulnerabilities. Among these is a defect in Orchard action encoding that could lead to node crashes and potential consensus splits between clients. The updates have been deployed by mining pools running both implementations, and there are no signs of the vulnerabilities being exploited. User funds and privacy remain secure, with no risk of ZEC inflation. Users are advised to upgrade promptly and review the official announcement for full details.
