Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid low-privilege account on the E-Commerce Pack application - such as a registered customer or merchant - as confirmed by the PR:L CVSS metric; unauthenticated exploitation is not possible. … Additional conditions and limiting factors are described in the full assessment. |
