CVE-2020-6861
A flawed protocol design in the Ledger Monero app before 1.5.1 for Ledger Nano and Ledger S devices allows a local attacker to extract the master spending key by sending crafted messages to this app selected on a PIN-entered Ledger connected to a host PC.
Does this matter?
Lower severity and a low EPSS score (0.44%). Track it; it rarely justifies an emergency change on its own.
