SATWEI summary
A channel announcement naming the same node at both ends could crash Core Lightning 25.02 through 26.04 on every restart, at a cost to the attacker of only onchain fees; the fix landed in 26.04.1. Newsletter #429 pairs that disclosure with Oleksandr Kurbatov's protocol for multiparty silent payment inputs and Bitcoin Core's faster point releases for easily discoverable bugs.
