Zcashd in Zcash before 2.0.7-3 allows discovery of the IP address of a full node that owns a shielded address, related to mishandling of exceptions during deserialization of note plaintexts. This affects anyone who has disclosed their zaddr to a third party.

Security readout for executives and security teams

This issue could let someone connect a disclosed Zcash shielded address to the IP address of the full node that owns it. That is a privacy and metadata exposure risk, not described in the bundle as theft of funds or key compromise. Organizations or individuals operating Zcash full nodes with shielded addresses are most exposed if they disclosed a zaddr to another party and ran zcashd versions before 2.0.7-3. Prioritize remediation for teams relying on Zcash shielded-address privacy or running identifiable full nodes. This is not presented as a system takeover issue, but it can undermine anonymity assumptions and create business, personal-safety, or regulatory concerns. Mitigation focus: Upgrade zcashd to version 2.0.7-3 or later.; Review the Zcash security announcement for vendor guidance.; Identify any disclosed zaddrs used by vulnerable full nodes..
