All STM32 MCUs has a builtin bootloader stored in so-called system memory. The system memory is a ROM (read-only memory) which is created during the production of the MCU and can never be changed. When the MCU startup the Boot0 pin is asserted and if high (pulled up to VCC) the MCU will execute the bootloader.
