CLEANSTART-2026-DN56273 Applications using AesBytesEncryptor with the two-argument constructor or when passing a null IV generator and CBC as the encryption mode encrypt data with AES/CBC using a null (all-zero) initializ...

Security vulnerability affects the apache-nifi-registry package. Applications using AesBytesEncryptor with the two-argument constructor or when passing a null IV generator and CBC as the encryption mode encrypt data with AES/CBC using a null all-zero initialization vector...

Use Of A Broken Or Risky Cryptographic Algorithm

Spring Security is vulnerable to Use of a Broken or Risky Cryptographic Algorithm. The vulnerability is due to AesBytesEncryptor using AES/CBC with a null all-zero initialization vector, which allows an attacker to exploit predictable encryption and potentially infer relationships between encrypt...

CVE-2026-47842

A flaw was found in Spring Security. Applications configured to use AesBytesEncryptor with a two-argument constructor or a null Initialization Vector IV generator in Cipher Block Chaining CBC mode will encrypt data using a predictable, all-zero IV. This deterministic encryption allows an attacker...

CVE-2026-47842

Spring Security 's AesBytesEncryptor deterministically encrypts data with AES/CBC when the two-argument constructor is used or a null IV generator is passed with CBC mode, resulting in a null (all-zero) initialization vector . This causes identical plaintexts to always produce identical ciphertex...
