💉 CVE-2018-17144 Inflation Bug Disclosed in Full

On 20 September 2018, Bitcoin Core fully disclosed CVE-2018-17144: an optimization added in version 0.14 dropped a check for duplicate inputs, theoretically letting a miner build a block that double-spends and inflates the supply. The patch shipped on 18 September framed as the lesser DoS bug — the team withheld the full picture "to give times for systems to upgrade."
