Developers have disclosed a software vulnerability in Babylon, the Bitcoin staking protocol's BLS voting extension (block signature) mechanism. The vulnerability allows malicious validators to intentionally omit the block hash field when submitting voting extensions, potentially triggering other validators to crash at network epoch boundaries, thereby slowing down block production during critical consensus checks. There is currently no evidence that the vulnerability has been exploited in practice, but developers warn that it could be abused if not fixed. Babylon has not yet publicly responded with a fix.
