Bitcoin Lightning’s year-old security fixes still missing from 71% of flagged nodes

Nearly three-quarters of public Bitcoin Lightning nodes identified as exposed in August remained on affected software lines in October. An Oct. 21 study found that 71% of a group of 550 public LND nodes flagged during an Aug. 11 security disclosure were still operating on affected software release lines as of Oct. 13. Only about 10% had upgraded during that period, while 108 nodes were no longer classified as live. The findings suggest that security fixes are reaching some Lightning operators well after their release dates.
