Zcash Foundation releases Zebra 4.5.1 to fix a critical consensus security vulnerability

Foresight News reports that the Zcash Foundation has released Zebra version 4.5.1, addressing a critical consensus security vulnerability (GHSA-2prc-cj5x-4443). All node operators are strongly advised to upgrade immediately. This vulnerability stems from an incomplete fix for the P2SH Sigop counting issue in the previous version (4.5.0), which still poses a risk of consensus fork. Currently, there are no known workarounds; upgrading is the only solution.
