Weak hashing library (MDx) detected

• Rule ID: php_lang_weak_hash_md
• Languages: php
• Source: weak_hash_md.yml

Description

A weak hashing library can lead to data breaches and greater security risk.

Remediations

According to OWASP, MD5 is considered a weak hashing algorithms and therefore shouldn't be used.

❌ Avoid libraries and algorithms with known weaknesses:

  $encrypted = md5($input)

✅ Use stronger encryption algorithms when storing data.

  $encrypted = hash('sha256', $input)

Associated CWE

• CWE-327: Use of a Broken or Risky Cryptographic Algorithm

OWASP Top 10

• A02:2021 - Cryptographic Failures
