CVE-2018-6353: Electrum

High severity, CVSS 7.8. EPSS: 0.5% chance of exploitation in the next 30 days.

The Python console in Electrum through 2.9.4 and 3.x through 3.0.5 supports arbitrary Python code without considering (1) social-engineering attacks in which a user pastes code that they do not understand and (2) code pasted by a physically proximate attacker at an unattended workstation, which makes it easier for attackers to steal Bitcoin via hook code that runs at a later time when the wallet password has been entered, a different vulnerability than CVE-2018-1000022.

Affected products

• Electrum Electrum: up to and including 2.9.4; version 3.0.0 only; version 3.0.1 only; version 3.0.2 only; version 3.0.3 only; version 3.0.5 only
