CVE-2026-117602 is a high-severity flaw (CVSS 8.4) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
Electrum 4.6.0 before 4.7.2 contains an authorization bypass in the external plugin loader, which executes a plugin's __init__.py module when the plugin is marked enabled in the config file, without verifying its plugin-password signature. A rogue local process with write access to the Electrum data directory can place plugin code in the plugins/ folder and mark it enabled, causing arbitrary code execution inside the Electrum process.
