CVE-2022-40482: Laravel Framework

Medium severity, CVSS 5.3. EPSS: 0.9% chance of exploitation in the next 30 days.

The authentication method in Laravel 8.x through 9.x before 9.32.0 was discovered to be vulnerable to user enumeration via timeless timing attacks with HTTP/2 multiplexing. This is caused by the early return inside the hasValidCredentials method in the Illuminate\Auth\SessionGuard class when a user is found to not exist.

Affected products

• Laravel Framework: from 8.0.0, before 8.83.24 (fixed in 8.83.24); from 9.0.0, before 9.32.0 (fixed in 9.32.0)
