In complete honesty: if you have to ask this question, it's overwhelmingly unlikely that you have actually succeeded in breaking the security of AES. At best, you may have discovered a well-known attack against misuse of particular block cipher modes; for instance, plaintext recovery with a chosen-ciphertext attack against ECB, or blind manipulation of the plaintext with a ciphertext-only attack against unauthenticated CTR.
What property of AES do you believe that you've managed to compromise? Under what attack model did you conduct this attack? How was AES used? What block size and mode?
