Community Trust Score Verified 88 % Real Verified 8 votes Updated 16 minutes ago Bitcoinjs-lib maintainers issued security disclosures on October 26 identifying two bugs that can cause software to understate the miner fee a valid Bitcoin transaction would pay if broadcast and accepted. The fixes are included in versions 5.2.2, 6.1.9, and 7.0.4 for their respective release lines. The affected transaction format is the partially signed Bitcoin transaction (PSBT). BIP 174 defines PSBT as a method to pass transaction information and signatures between clients.
