Original NVD Description

sm-crypto provides JavaScript implementations of the Chinese cryptographic algorithms SM2, SM3, and SM4. A private key recovery vulnerability exists in the SM2 decryption logic of sm-crypto prior to version 0.3.14. By interacting with the SM2 decryption interface multiple times, an attacker can fully recover the private key within approximately several hundred interactions. Version 0.3.14 patches the issue.
