Inverting interrupt edge (STM32 wake up pin)
Yes, the WKUP pin works like that. If you really need standby state, you pretty much have no other choice left to wake up the device.
You can, however, put a simple inverting transistor in front the the WKUP pin like this:

Check the data sheet, you might be able to spare R2 if a proper pull-down resistor can be switched on for WKUP inside the chip.
