Severity
CWE	CWE-327: Use of a Broken or Risky Cryptographic Algorithm
OWASP	A02:2021 - Cryptographic Failures
Confidence Level	High
Impact Level	Medium
Likelihood Level	High

Description#

The code is using ECB (Electronic Codebook) mode for encryption, which does not properly hide patterns in the data and is considered insecure. Instead, you should use authenticated encryption modes like AES-GCM or ChaCha20Poly1305.

Impact#

If ECB mode is used, attackers can detect patterns and potentially recover sensitive information from encrypted data, even without the key. This can lead to exposure of confidential data and weaken the overall security of your application.
