Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | No special conditions - remote unauthenticated exploitation against any WordPress site with the Feed KuantoKusta for WooCommerce - Free plugin (versions through 5.3) installed and active, reachable over HTTP/HTTPS. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L describes a network-reachable, low-complexity, unauthenticated, no-interaction attack with high confidentiality impact and scope change - the canonical profile of a serious SQLi against a public WordPress endpoint. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An opportunistic attacker scanning the internet for WordPress sites running the Feed KuantoKusta plugin sends a crafted HTTP GET or POST request to the vulnerable feed endpoint, injecting UNION-based or time-based SQL payloads into a tainted parameter. Because no authentication is required and complexity is low, the attacker extracts wp_users password hashes and WooCommerce customer order data (PII, addresses, possibly partial payment metadata) in a single automated pass. … |
| Remediation | No vendor-released patched version is independently confirmed in the supplied data - the input only specifies vulnerable range '≤5.3' without naming a fixed release - so administrators should consult the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/feed-kuantokusta-for-woocommerce/vulnerability/wordpress-feed-kuantokusta-for-woocommerce-free-plugin-5-3-sql-injection-vulnerability for the latest fixed version and upgrade to any release above 5.3 if published. … Detailed patch versions, workarounds, and compensating controls in full report. |
