Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.6, GlancesActions.run() in glances/actions.py ignores --disable-config-exec for on-alert action commands and invokes secure_popen() with shell operators enabled, allowing configured redirection, command chaining, or pipes to execute when an alert triggers. This issue is fixed in 4.5.6.
