Vulnerability AssessmentAI
| Exploitation | No authentication, user interaction, or special privileges are required (CVSS PR:N/UI:N/AC:L), so a default installation of any Tutor LMS version prior to 4.0.6 is exploitable by remote unauthenticated users over the network. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine high-priority issue rather than an inflated CVSS score. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
