Technical details
The plugin loader in Electrum executes a plugin's __init__.py module when the plugin is marked as enabled in the configuration file without properly verifying the plugin's cryptographic signature. A local attacker with write access to the plugins directory can place unsigned plugin code and mark it enabled in the config, achieving arbitrary code execution within the Electrum process. The fix adds an authorization check via decorator to prevent loading of unauthorized plugins.
