Zcash Foundation Releases Critical Zebra 4.4.0 Security Update
- Security Vulnerability Fixes: The Zcash Foundation has released Zebra 4.4.0, addressing five security vulnerabilities, three of which are consensus-critical, necessitating immediate upgrades from all node operators to prevent potential attacks and network splits.
- Severe Vulnerability Impact: The most critical flaw allowed attackers to permanently halt a node's ability to discover new blocks with just one connection, exploiting weaknesses in Zebra's information sharing and downloading mechanisms, rendering the attack invisible to standard monitoring tools and increasing network security risks.
- Historical Attack Context: According to CertiK, April 2026 marked the most hacked month in crypto history with losses around $651 million, highlighting the current vulnerabilities in the crypto market; although Zcash was not directly targeted, the urgency for the update is evident given the volume of attacks.
- Market Response and Recommendations: At the time of the update's release, ZEC was trading at $377.46 with a market cap of $6.28 billion, and the Foundation advises all node operators to upgrade immediately to avoid exposure to the five known vulnerabilities, ensuring the security and stability of the network.
