Morphology

letter + bomb

The meaning (an explosive device concealed in mailed correspondence) is directly and compositionally derived from combining 'letter' (mailed message) with 'bomb' (explosive device). This is a regular compound/nominal construction that maps straightforwardly onto its parts and is cross-linguistically common, so a B1 learner who knows both words would very likely infer the meaning.

Etymology

The noun letter bomb comes from the shocking image of a small bomb hidden inside a letter or envelope. When the envelope is opened the device is 'made to go off when opened', so the phrase means 'an explosive device hidden in an envelope or package'.
