Vulnerability in shopware/platform (CVE-2026-48011)
Summary
Vulnerability in shopware/platform (CVE-2026-48011). Risk of unauthorized operations or information disclosure. Exploitable via password_verify. Mitigation: upgrade to 6.6.10.18 or later.
Original description
The description as published by the source.
Summary
There is a Proof of Concept which is able to enumerate the usernames of administrator users. This was possible by performing a timing attack.
Details
The faulty code exists in src/Core/Framework/Api/OAuth/UserRepository.php:
public function getUserEntityByUserCredentials(
string $username,
#[\SensitiveParameter]
string $password,
string $grantType,
ClientEntityInterface $clientEntity
): ?UserEntityInterface {
if ($this->loginConfigService->getConfig()?->useDefault === false) {
// never allow login via password if the default login is disabled (e.g. using SSO only)
return null;
}
$builder = $this->connection->createQueryBuilder();
$user = $builder->select('user.id', 'user.password')
->from('user')
->where('username = :username')
->setParameter('username', $username)
->fetchAssociative();
// PATH 1: EARLY RETURN WHEN USERNAME IS NOT FOUND
if (!$user) {
return null;
}
// PATH 2: VERIFY PASSWORD IF USER IS FOUND
if (!password_verify($password, (string) $user['password'])) {
return null;
}
return new User(Uuid::fromBytesToHex($user['id']));
}
Subroutine getUserEntityByUserCredentials() is called when an auth request is sen…
