Is Core Rs Albatross affected by EUVD-2026-22061?

Nimiq core-rs-albatross validators below version 1.3.0 are vulnerable to remote denial-of-service attacks through malformed Tendermint proposals, potentially disrupting consensus participation and validator availability across the Nimiq blockchain network.

DescriptionNVD

nimiq/core-rs-albatross is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. Prior to version 1.3.0, an untrusted peer could crash a validator by publishing a signed tendermint proposal message where signer == validators.num_validators(). ProposalSender::send uses > instead of >= for the signer bounds check, so the equality case passes and reaches validators.get_validator_by_slot_band(signer), which panics with an out-of-bounds index before any signature verification runs. This issue has been fixed in version 1.3.0.

AnalysisAI

Nimiq core-rs-albatross validators prior to version 1.3.0 can be remotely crashed via malformed Tendermint proposals. An unauthenticated network attacker exploits an off-by-one bounds check error (using > instead of >=) to trigger an out-of-bounds index panic before signature verification occurs. …

RemediationAI

Within 24 hours: Identify all Nimiq validator instances running core-rs-albatross versions below 1.3.0 and assess current deployment inventory. Within 7 days: Apply vendor-released patch to version 1.3.0 or later across all validator nodes, beginning with non-critical validators to validate stability. …
