CSA-2026-001: Tachyon Description Name: CSA-2026-001: Tachyon Criticality: Critical (Catastrophic Impact; Possible Likelihood per ACMv1.2) Affected versions: All versions of CometBFT Affected users: Validators and protocols relying on block timestamps Description A consensus-leve...
Name: ASA-2025-003: Invalid BitArray handling can lead to network halt Criticality: High (Considerable Impact; Possible Likelihood per ACMv1.2) Affected versions: <= v0.38.18, <= v0.37.15, and main development branches Affected users: Validators, Full nodes, Users Description A b...
CometBFT is a distributed, Byzantine fault-tolerant, deterministic state machine replication engine. In the blocksync protocol peers send their base and latest heights when they connect to a new node (A), which is syncing to the tip of a network. base acts as a lower ground and i...
Name: ASA-2025-002: Malicious peer can stall network by disseminating seemingly valid block parts Component: CometBFT Criticality: High (Catastrophic Impact; Possible Likelihood per ACMv1.2) Affected versions: <= v0.38.16, v1.0.0 Affected users: Validators, Full nodes, Users Desc...
Name: ASA-2024-011: Vote Extensions: Panic when receiving a Pre-commit with an invalid data Component: CometBFT Criticality: High (Considerable Impact, and Possible Likelihood per ACMv1.2) Affected versions: >= 0.38.x, unreleased v1.x and main development branches Affected users:...
Name: ASA-2024-009: State syncing validator from malicious node may lead to a chain split Component: CometBFT Criticality: Medium (ACMv1.2: I:Moderate; L: Possible) Affected versions: >= 0.34.0, <= 0.34.33, >=0.37.0, <= 0.37.10, >= 0.38.0, <= 0.38.11 Summary The state sync protoc...
Name: ASA-2024-008: Instability during blocksync when syncing from malicious peer Component: CometBFT Criticality: Medium (ACMv1: I:Moderate; L: Possible) Affected versions: < v0.38.7 Summary An issue was identified for nodes syncing on an existing network during blocksync in whi...
ASA-2024-004: Default configuration param for Evidence may limit window of validity Component: CometBFT Criticality: Low Affected versions: All Affected users: Validators, Chain Builders + Maintainers Summary A default configuration in CometBFT has been found to be small for comm...
Summary A vulnerability in CometBFT’s validation logic for VoteExtensionsEnableHeight can result in a chain halt when triggered through a governance parameter change proposal on an ABCI2 Application Chain. If a parameter change proposal including a VoteExtensionsEnableHeight modi...
Amulet Security Advisory for CometBFT: ASA-2023-002 Component: CometBFT Criticality: Low Affected versions: All Affected users: Validators, Chain Builders + Maintainers Summary A default configuration in CometBFT has been found to be large for common use cases, and may affect blo...
CometBFT is a Byzantine Fault Tolerant (BFT) middleware that takes a state transition machine and replicates it on many machines. An internal modification made in versions 0.34.28 and 0.37.1 to the way struct PeerState is serialized to JSON introduced a deadlock when new function...
CometBFT is a Byzantine Fault Tolerant (BFT) middleware that takes a state transition machine and replicates it on many machines. The mempool maintains two data structures to keep track of outstanding transactions: a list and a map. These two data structures are supposed to be in...
