EUVD-2026-28654

ZEBRA is a Zcash node written entirely in Rust. Prior to zebrad version 4.3.1 and prior to zebra-chain version 6.0.2, Orchard transactions contain a rk field which is a randomized validating key and also an elliptic curve point. The Zcash specification allows the field to be the identity a "zero"...

CVE-2026-41584

ZEBRA (the Zebra node implementation for Zcash) is affected by CVE-2026-41584 due to the rk field in Orchard transactions. Prior to zebrad 4.3.1 and zebra-chain 6.0.2, an identity value for rk (the randomized validating key and elliptic-curve point) could trigger a panic in the orchard crate used...

GHSA-29X4-R6JV-FF4W Zebra Vulnerable to Denial of Service via Interrupted JSON-RPC Requests from Authenticated Clients

A vulnerability in Zebra's JSON-RPC HTTP middleware allows an authenticated RPC client to cause a Zebra node to crash by disconnecting before the request body is fully received. The node treats the failure to read the HTTP request body as an unrecoverable error and aborts the process instead of...
