### 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`

### 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:**

``` 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); } ```
