I mean a blender isn't exactly the worst things to have security bits on.
Looks like a job for a regular flathead and a grinding wheel.
Thought they might sell these specialty tools online, but 3 minutes of searching came up with nothing. Might be time to get creative.
Do you have the room to get a Dremel in there the cut it so a regular flathead will work?
If not, maybe try to use needle noise pliers as your screwdriver.
As a last resort, pick up a cheap screwdriver and cut it to make it slotted.
Edit: I love how quickly several people have commented with links to the needed tools. Thanks to all of you!

I had to cut the casing open in order to discover why I couldn't unscrew the fourth.

Were you able to fix it?
I destroyed the casing to learn why my Phillips screw driver couldn't grab the screw head.
Oh, I have that bit. Its not even the weirdest
Right to Repair
