CVE-2026-104429

The Zebra (zebrad) software, versions 5.0.0 before 6.0.0-rc.0 , is vulnerable to a mempool admission bypass. The root cause is that the system fails to apply per-peer mempool admission caps to transactions received as direct P2P tx messages , as these are queued without recording the sending peer...

CVE-2026-104428

The zebra-rpc component in the Zcash Foundation's Zebra node (versions before 11.0.0 ) is vulnerable to a Denial of Service (DoS) . The getblock RPC method panics when handling a side-chain block with verbosity 2 because a -1 confirmations sentinel is converted to u32 using .expect() , causing th...

CVE-2026-104428 Zebra before 11.0.0 Denial of Service via getblock Verbosity 2

The getblock RPC method in zebra-rpc before 11.0.0, used by the Zcash Foundation's Zebra node, panics on verbosity 2 for a side-chain block because the block's -1 confirmations sentinel is converted to u32 with .expect, aborting the process. Remote unauthenticated attackers, directly or through...

CVE-2026-104426 Zebra before 6.1.0 Quadratic Complexity DoS via Block Transparent Value Check

Zebra before 6.1.0 contains an inefficient algorithmic complexity vulnerability in remainingtransactionvalue that clones the entire block-level spent-UTXO map per transaction during contextual verification. Attackers can mine or seed the mempool with roughly 26,000 minimal single-input transactio...

CVE-2026-104426

Zebra versions before 6.1.0 are susceptible to an inefficient algorithmic complexity vulnerability (CWE-407) within the remaining_transaction_value function. The root cause is the cloning of the entire block-level spent-UTXO map for every transaction during contextual verification. This allows an...

CVE-2026-104425 Zebra before 6.1.0 Batch-Verification Poisoning DoS via Unattributed Pushed Transactions

ZcashFoundation Zebra before 6.1.0 contains a resource exhaustion vulnerability that allows unauthenticated peers to degrade block processing by pushing transactions with invalid Orchard proofs without being misbehavior-scored. Attackers can repeatedly push invalid proofs into the shared halo2...

CVE-2026-104425

ZcashFoundation Zebra versions before 6.1.0 are susceptible to a resource exhaustion vulnerability. Unauthenticated peers can degrade block processing by pushing transactions containing invalid Orchard proofs without being misbehavior-scored. By repeatedly pushing these invalid proofs into the sh...

CVE-2026-104424 Zebra before 6.1.0 Incorrect Block Size Calculation in getblocktemplate

Zebra before 6.1.0 contains an incorrect calculation vulnerability in its ZIP-317 block template selector that omits header and transaction-count size from the block budget. Attackers can place valid selectable transactions in a victim miner's mempool to shape templates into oversized blocks,...

CVE-2026-104423

The Zebra (zebrad) software, specifically versions before 6.2.1 , is susceptible to an asymmetric resource consumption vulnerability (CWE-405). This flaw allows unauthenticated peers to stall block verification by flooding the shared unprioritized Halo2 verification queue with zero-fee transactio...

CVE-2026-104421

Zebra versions before 6.2.1 are vulnerable to an incomplete cleanup vulnerability (CWE-459). This flaw allows unauthenticated peers to prevent the downloading of valid blocks by leaving rejected hashes in SentHashes . An attacker can transmit a contextually invalid block that shares an honest blo...
