As to "what to do now," chances are that the bent pin will break with an attempt to bend it back into place, even if you take the camera apart to get to it. (Also, the critical nature of the pin spacing makes bending it back into place unlikely.)
So, the connector to which the pins are attached will probably need to be replaced. Problem with that is the connector is likely soldered onto a main circuit board, possibly a multi-layer circuit board. It may be difficult to find a shop willing to attempt such a repair. In the latter case, the entire circuit board may require replacement.
I am sorry to be the bearer of bad tidings; and I hope that I am wrong...

Pins can be straightened, IF YOU KNOW WHAT YOU'RE DOING. It does require disassembly.
I strongly recommend against dismantling your gear unless you know what you are doing at every level. Anti static mats and straps are a must. ESD safe solder stations are also a must. You can get yourself in deep trouble real quick with one wrong move.
Most, but not all, CF card reader pin assemblies are on a sub-assembly in the high end cameras. Most consumer cameras have the pins soldered to the main board and a skilled tech can change out individual pins. Main board replacement requires the manufacturer' proprietary interfaces and adjustment software, usually found only at authorized shops.
CF cards and pins do require a bit more attention to what you are doing. I've never damaged pins in the nine years of using them. If you do break a pin, remove the battery immediately, as the loose pin can migrate to an IC and blow the thing up.
And if a card becomes damaged do not continue to use it.
And while on the subject of user repairs, resist the urge to use any lubricant of any sort on any part of a modern camera or lens. Most techs tack on an extra idiot fee for equipment that's been tampered with.
SD cards may be harder, though not impossible, to damage, but sure are easier to lose.
