How to Fix GHSA-869w-47c6-fq8q

To remediate this vulnerability, upgrade all affected Github.com/babylonlabs io/babylon dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/babylonlabs-io/babylon fixed: 1.1.0 
Upgrade github.com/babylonlabs-io/babylon to 1.1.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

How to Check if You Are Affected

To determine whether your application is affected by GHSA-869w-47c6-fq8q, inspect your project dependencies for Github.com/babylonlabs io/babylon:

inspect dependencies for github.com/babylonlabs-io/babylon

Analyze the terminal output to locate any version of Github.com/babylonlabs io/babylon in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-190: Integer Overflow or Wraparound, where the product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. this occurs when an integer value is incremented to a value that is too large to store in the associated representation. when this occurs, the value may become a very small or negative number. In Github.com/babylonlabs io/babylon, 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 Minting large amount of tokens through ibc transfer and then depositing them in validator rewards pool (via `DepositValidatorRewardsPool` message) can lead to integer overflow panic when calculating `cumulative_reward_ratio` for the validator. This calculation happens in `x/epoching` module `EndBlocker`, thus the panic will halt the chain. ### Impact Denial of Service - Due to panic in the `EndBlocker` Babylon Genesis will halt
