Core Lightning warns attackers are targeting unpatched nodes

The significance here is less the specific exploit than the disclosure posture: Core Lightning is naming active targeting while withholding the attack's mechanics, which leaves unpatched operators unable to judge their own exposure beyond the version cutoff. Anyone running older Lightning infrastructure, particularly node operators with routing liquidity at stake, faces the immediate decision the advisory frames as urgent. The open question is whether the withheld details reflect a deliberate embargo to buy patching time or simply an incomplete picture — and whether other Lightning implementations surface similar warnings.
