 FREAK

FREAK, which stands for "Factoring RSA Export Keys," is a vulnerability that was discovered in certain implementations of SSL/TLS protocols. It was revealed in March 2015 and allowed attackers to exploit weak encryption that was used in some older systems, particularly those that employed export-grade cryptography. The vulnerability specifically targeted systems that accepted export-grade ciphers, which were designed to comply with U.S. regulations limiting the strength of encryption that could be exported overseas.
