Successful exploitation only alters log content; it does not provide direct code execution or system compromise."}}}}, "created": "2026-04-14T16:21:39.016900+00:00", "title": "Improper Encoding Allows Log Injection in Schneider Electric PowerChute Serial Shutdown", "updated": "2026-04-15T15:30:06.827961+00:00", "vendors": ["schneider-electric", "schneider-electric$PRODUCT$powerchute_serial_shutdown"]}
