The issue is rated CVSS 7.2 (High) and requires PR:H, so exploitation is limited to trusted staff or attackers who already control a Shop Manager account; no public exploit code or CISA KEV entry is present in the provided data. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires an authenticated user with the WooCommerce Shop Manager role (PR:H) on a site running Cost of Goods for WooCommerce version ≤3.5.2; no end-user interaction is needed (UI:N) and the vector is network-reachable (AV:N) through the normal WordPress admin/AJAX surface. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 vector (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) yields a 7.2 (High) base score driven by full triple-impact (C:H/I:H/A:H), but the PR:H metric is the decisive limiting factor: exploitation requires an authenticated account with Shop Manager (high) privileges, per both the description ('Shop manager PHP Object Injection') and the vector. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
