Morphology

can + of + worm

The literal image of opening a 'can' full of 'worms' suggests a messy, cascading problem, so a learner who knows the constituents can plausibly infer that it refers to revealing or creating many complications. However, the expression is metaphorical and conventionalized in English, so the exact pragmatic sense ('a situation that will lead to many further problems') is not fully predictable without prior exposure.

Etymology

The idiom can of worms may come from the image of opening a tin can full of live worms that wriggle out and spread everywhere. Because you can't put them back, the phrase means a small action that will start 'many more problems'.
