Last modified

CVE-2017-12842 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. Bitcoin Core before 0.14 allows an attacker to create an ostensibly valid SPV proof for a payment to a victim who uses an SPV wallet, even if that payment did not actually occur. Completing the attack would cost more than a million dollars, and is relevant mainly only in situations where an autonomous system relies solely on an SPV proof for transactions of a greater dollar amount.. EPSS estimates a 2.16% chance of exploitation in the next 30 days.
