TREE NEWS update: LNbits issued an emergency security warning urging all users to shut down their servers immediately until a critical vulnerability is patched, following multiple attacks. Operator @KevinR4 reported that attackers created new accounts and withdrew funds, costing him 2,285,545 sats over roughly five hours. LNbits said a security patch is expected within 24 to 48 hours.
LNbits Urges Users to Shut Down Servers After Attacks
The urgency here stands out: LNbits is telling operators to take servers offline rather than wait for a fix, which signals the flaw is exploitable in the wild, not theoretical. The reported losses came through account creation and withdrawal, pointing at the account and wallet flow rather than a downstream integration. That matters for anyone running a self-hosted Lightning instance, where the operator carries the exposure directly. The open question is whether the promised patch closes the vector or only narrows it, and whether more operators report similar drains in the meantime.
