CVE intelligence and bounded remediation

CVE-2024-34360 — go-spacemesh is a Go implementation of the Spacemesh protocol full node

High CVSS 8.2

go-spacemesh is a Go implementation of the Spacemesh protocol full node. Nodes can publish activations transactions (ATXs) which reference the incorrect previous ATX of the Smesher that created the ATX. ATXs are expected to form a single chain from the newest to the first ATX ever published by an identity. Allowing Smeshers to reference an earlier (but not the latest) ATX as previous breaks this protocol rule and can serve as an attack vector where Nodes are rewarded for holding their PoST data for less than one epoch but still being eligible for rewards. This vulnerability is fixed in go-spacemesh 1.5.2-hotfix1 and Spacemesh API 1.37.1.

Matched remediation archetype

General vulnerability remediation

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Confirm the affected component, deployment paths, reachable interfaces, and enabled features from inventories and configuration, without probing production destructively.
  • Compare the advisory's affected conditions with the repository lockfiles, build manifests, artifacts, and runtime inventory.
  • Identify data sensitivity, trust boundaries, and privilege level for every confirmed affected deployment.

Remediate safely

  • Apply a vendor-supported fix or remove the affected component or feature; record the selected change and its source in the repository.
  • Update direct and transitive dependency locks, generated artifacts, deployment manifests, and asset inventories together.
  • Add a regression test for the documented unsafe condition using inert inputs and preserve rollback instructions.
