Verification cache poisoning allows forged Nostr events to bypass signature validation
The nostr-relay-pool crate cached the result of event signature verification before the check was actually performed. Because the entry was inserted unconditionally, a first delivery whose signature failed was still recorded in the cache. A subsequent delivery of the same event identical ID, but...
RUSTSEC-2026-0232 Processing of unverified relay events
The processed events received from a relay through admission-policy and database paths before verifying that the serialized fields matched the claimed event ID and signature. In particular, a database result for the claimed ID could cause verification to be skipped. The verification cache also...
CVE-2026-40880
The CVE-2026-40880 issue affects Zebra (Zcash node) prior to Zebrad 4.3.1 and zebra-consensus 5.0.2. A logic error in Zebra’s transaction verification cache allowed a malicious miner to exploit height-dependent validity (e.g., an expiry height or upgrade) by submitting a transaction valid at heig...
CVE-2026-40880 Zebra: Cached Mempool Verification Bypasses Consensus Rules for Ahead-of-Tip Blocks
ZEBRA is a Zcash node written entirely in Rust. Prior to zebrad version 4.3.1 and zebra-consensus version 5.0.2, a logic error in Zebra's transaction verification cache could allow a malicious miner to induce a consensus split. By carefully submitting a transaction that is valid for height H+1 bu...
CVE-2026-40880: Comparison Using Wrong Factors
ZEBRA is a Zcash node written entirely in Rust. Prior to zebrad version 4.3.1 and zebra-consensus version 5.0.2, a logic error in Zebra's transaction verification cache could allow a malicious miner to induce a consensus split. By carefully submitting a transaction that is valid for height H+1 bu...
CVE-2026-34377 Zebra has a Consensus Failure due to Improper Verification of V5 Transactions
ZEBRA is a Zcash node written entirely in Rust. Prior to zebrad version 4.3.0 and zebra-consensus version 5.0.1, a logic error in Zebra's transaction verification cache could allow a malicious miner to induce a consensus split. By matching a valid transaction's txid while providing invalid...

Zebra data falsification issue vulnerabilities
Zebra is an open-source implementation of Zcash full node written in Rust by the Zcash Foundation. Zebra has a vulnerability related to data forgery, which stems from logical errors in the transaction verification cache. This vulnerability could allow malicious miners to manipulate consensus...
