Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The target WordPress site must have the ThemeGrill User Registration Stripe plugin installed and activated at version 1.3.12 or earlier, with the affected endpoint reachable over HTTP/HTTPS - the standard deployment for a public WordPress signup page. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS vector AV:N/AC:L/PR:N/UI:N indicates fully remote, low-complexity, unauthenticated exploitation with no user interaction, which is the worst-case pre-conditions profile and aligns with the 'Unauthenticated' qualifier in the Patchstack report. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker scanning the internet for WordPress sites fingerprints the User Registration Stripe plugin via its static assets or REST namespace, then sends a crafted HTTP request directly to the vulnerable AJAX or REST endpoint without any session cookie or nonce. Because the handler skips capability checks, the request succeeds and the attacker modifies registration or payment-related state - for example creating users, altering subscription records, or manipulating plan assignments. … |
| Remediation | Upstream fix available per Patchstack advisory; released patched version not independently confirmed in the provided data, so administrators should consult https://patchstack.com/database/wordpress/plugin/user-registration-stripe/vulnerability/wordpress-user-registration-stripe-plugin-1-3-12-broken-access-control-vulnerability for the exact fixed release (expected to be the next version after 1.3.12) and upgrade via the WordPress plugin dashboard. … Detailed patch versions, workarounds, and compensating controls in full report. |
