GMS-2020-512: Insecure Cryptography Algorithm in simple-crypto-js

September 3, 2020 (updated September 29, 2021)

Versions of simple-crypto-js use AES-CBC with PKCS#7 padding, which is vulnerable to padding oracle attacks. This may allow attackers to break the encryption and access sensitive data.
