Core Lightning warns of critical vulnerabilities, urges nodes switch to offline mode

Core Lightning developers have identified multiple serious vulnerabilities in Bitcoin Lightning Network payment software after reviewing a large batch of AI-generated security reports, CoinDesk reported. The team strongly urged node operators who cannot apply updates immediately to restart in --offline mode, which blocks routing connections, rather than shutting nodes down entirely. Specific details on the vulnerabilities and their potential impact will remain undisclosed for two weeks to prevent attackers from reverse-engineering the patched code and exploiting the flaws. CoinDesk reported a signed patch release is expected once developer verification is complete, and users should update promptly.
