Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-347: Improper Verification of Cryptographic Signature, where the product does not verify, or incorrectly verifies, the cryptographic signature for data. In Github.com/babylonlabs io/babylon/v4, 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 The BIP-322 signature verification does not enforce the SIGHASH value to be SIGHASH_ALL, and therefore is not strictly following the [spec](https://bips.dev/322/). ### Impact Non-compliant BIP-322 signatures in proof of possessions can be accepted by the chain.
