Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-754: Improper Check for Unusual or Exceptional Conditions, where the product does not check or incorrectly checks for unusual or exceptional conditions that are not expected to occur frequently during day to day operation of the product. In Github.com/babylonlabs io/babylon/v2, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary Sending a message that modifies the validator set at the epoch boundary halts the chain. ### Impact Denial of Service - Comos-sdk prevents modifying the validator set from two different modules - https://github.com/cosmos/cosmos-sdk/blob/release/v0.50.x/types/module/module.go#L811. Such an operation leads to panic and chain halt. ### Detailed Post mortem https://boiling-lake-106.notion.site/2025-06-18-Genesis-mainnet-chain-halt-post-mortem-229f60cc1b5f80b7adf5e3ea0541ea87
