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.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
