Not quite likely unless the film can is leaking light also. That's why there is always an instruction that says "Load film under subdued lighting." Usually if film are kept too long, the colour cast should be uniform.
Can check the negatives to see if there is a darker tone across the whole stretch of film and if only a roll is affected or it is consistent. If only one roll is affected, try not to put film cans under bright sunlight. Best to keep them properly in the can and in a compartment of the camera bag. If all the rolls you shot are affected, check whether you have damaged the camera back, there should be some kind of a slot for the edges of the back to sit in to block out the light. If there is a window to show the film used, check the foam gasket to see if it seals tightly against the film can when the back is closed. If the camera back is dented, you will probably need to buy another one to replace it or send it to the service centre.
So far, I've been assuming it's film. If this is in the case of digital, just send the camera back for servicing, probably nothing much you can do.
