要点
- CVE-2026-48488 は phpmyfaq/phpmyfaq, thorsten/phpmyfaq に影響する深刻度「低」 (CVSS 2.7) の脆弱性です。
- 今後30日間に悪用される確率(EPSS):0.18%(全脆弱性の 7.8% より高い)。
- 対処:4.1.4 以降に更新してください。
概要
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:
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);
}
