In the principle (MAC is a compression function) there's always a probability of collision. The task is make the probability negligible. Wikipedia (Cryptographic_hash_function) claims "It requires a hash value at least twice as long as that required for preimage-resistance; otherwise collisions may be found by a birthday ...
A birthday attack is a type of cryptographic attack that exploits the mathematics behind the birthday problem in probability theory. This attack can be used to abuse communication between two or more parties. The attack depends on the higher likelihood of collisions found between random attack attempts … See more As an example, consider the scenario in which a teacher with a class of 30 students (n = 30) asks for everybody's birthday (for simplicity, ignore leap years) to determine whether any two students have the same … See more • Collision attack • Meet-in-the-middle attack See more • "What is a digital signature and what is authentication?" from RSA Security's crypto FAQ. • "Birthday Attack" X5 Networks Crypto FAQs See more Given a function $${\displaystyle f}$$, the goal of the attack is to find two different inputs $${\displaystyle x_{1},x_{2}}$$ such that $${\displaystyle f(x_{1})=f(x_{2})}$$.

This attack exploits known blockcipher vulnerabilities (collision/birthday attacks) against 64-bit block ciphers like 3DES and Blowfish. It affects any protocol making use of these “light” blockciphers along with CBC-mode for a long period of time without re-keying.
