phpMyFAQ has Weak Cryptography - SHA1 for Password Hashing

  • Disclosed: 23.06.2026
  • Updated: 11.10.2026 10:22

Summary

Attachment passwords are hashed using SHA-1, a cryptographically broken algorithm. SHA-1 has been vulnerable to collision attacks since 2017 (SHAttered).

Details

Affected File : phpmyfaq/src/phpMyFAQ/Attachment/AbstractAttachment.php

<img width="810" height="427" alt="image" src="https://github.com/user-attachments/assets/6499a008-3ece-4291-8296-f1d3303ba35c" />

Impact

  • An attacker can generate SHA-1 collisions to bypass attachment protection
  • Risk of password cracking if database is compromised
  • Estimated cracking time: < 1 minute for standard attachment

Solution

Use bcrypt:

php
public function setPassword(string $password): void
{
    $this->passwordHash = password_hash($password, PASSWORD_BCRYPT);
}

public function verifyPassword(string $plainPassword): bool
{
    return password_verify($plainPassword, $this->passwordHash);
}
