Yes, of course it is possible - many PLD manufacturers have app notes showing how to do it with processors far less capable than an STM32!
''Is there some libraries for JTAG master?''
The tricky part is not the JTAG - that's just a matter lf bit-banging a few pins;
The information you really need is the specific protocol/process required for updating the particular CPLD that you are actually using. For that, of course, you will need to refer to
documentation from the CPLD manufacturer...
