CVE-2026-44498

ZEBRA is a Zcash node written entirely in Rust. Prior to version 4.4.0, Zebra's block validator undercounts transparent signature operations against the 20000-sigop block limit MAXBLOCKSIGOPS, allowing it to accept blocks that zcashd rejects with bad-blk-sigops. A miner who produces such a block...

CVE-2026-41584

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-2026-44499

ZEBRA (Zcash node, Rust) before 4.4.0 contains a composite DoS in the block discovery pipeline. An unauthenticated remote attacker can, via a single TCP connection, exploit three independent weaknesses in the gossip, syncer, and download subsystems to create a monotonically growing block deficit ...

EUVD-2026-28655

ZEBRA is a Zcash node written entirely in Rust. From zebrad versions 2.2.0 to before 4.3.1 and from zebra-rpc versions 1.0.0-beta.45 to before 6.0.2, 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...

ZEBRA is a Zcash node written entirely in Rust. Prior to zebrad version 4.3.1 and prior to zebra-script version 5.0.2, after a refactoring, Zebra failed to validate a consensus rule that restricted the possible values of sighash hash types for V5 transactions which were enabled in the NU5 network...

CVE-2026-41583 ZEBRA: Consensus Divergence in Transparent Sighash Hash-Type Handling

ZEBRA is a Zcash node written entirely in Rust. Prior to zebrad version 4.3.1 and prior to zebra-script version 5.0.2, after a refactoring, Zebra failed to validate a consensus rule that restricted the possible values of sighash hash types for V5 transactions which were enabled in the NU5 network...

PT-2026-39149

Name of the Vulnerable Software and Affected Versions ZEBRA versions prior to 4.4.0 Description A composite denial-of-service issue in the block discovery pipeline allows an unauthenticated remote attacker to permanently stop all new block discovery on a targeted node. The attack leverages three...

zebra 安全漏洞

Zebra is an open-source implementation of Zcash full node written in Rust by the Zcash Foundation. Versions of Zebra prior to 4.4.0 contained a security vulnerability, which was caused by a combined denial-of-service vulnerability in the block discovery pipeline. This vulnerability could allow...

Zebra is an open-source Zcash implementation built using Rust by the Zcash Foundation. Versions of Zebra prior to 4.4.0 contained security vulnerabilities. These vulnerabilities stemmed from excessive buffer sizes allocated for multiple inbound deserialization paths, which could allow attackers t...

zebra 安全漏洞

Zebra is an open-source Zcash implementation built using Rust by the Zcash Foundation. Versions of Zebra prior to 4.3.1 contained security vulnerabilities. These vulnerabilities stemmed from the use of sighash hash types for V5 transactions and the standard hash type used for V4 transactions, whi...

zebra 安全漏洞

Zebra is an open-source Zcash implementation built with Rust by the Zcash Foundation. Versions of Zebra prior to 4.4.0 contained security vulnerabilities; these vulnerabilities stemmed from the block verifier underestimating the number of transparent signature operations, which could lead to...

zebra 安全漏洞

Zebra is an open-source Zcash implementation built using Rust by the Zcash Foundation. There were security vulnerabilities in versions 2.2.0 to 4.3.1 of Zebra. These vulnerabilities stemmed from the JSON-RPC HTTP middleware disconnecting connections when the request body was not fully received,...

zebra 安全漏洞

Zebra is an open-source Zcash implementation built using Rust by the Zcash Foundation. Versions of Zebra prior to 4.3.1 contained a security vulnerability. This vulnerability occurred when the rk field in Orchard transactions was set to an identity value, causing the Orchard crate to crash and...

PT-2026-38618

Name of the Vulnerable Software and Affected Versions Zebra versions 4.3.1 through 4.3.1 Description Insufficient error handling during sighash computation can lead to consensus divergence. When an invalid sighash type is encountered, the system fails to return an error, leaving the input sighash...

PT-2026-38619

Zebra's block validator undercounts transparent signature operations against the 20000-sigop block limit MAX BLOCK SIGOPS, allowing it to accept blocks that zcashd rejects with bad-blk-sigops. A miner who produces such a block can split the network: Zebra nodes follow the offending chain while...
