Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold a valid subscriber-level WordPress account on the target site - confirmed by the CVSS PR:L metric and the vulnerability title naming subscriber as the exploiting role. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 4.3 (Medium) reflects network accessibility (AV:N), low complexity (AC:L), low privilege requirement (PR:L), no user interaction (UI:N), unchanged scope, and integrity-only impact (I:L, C:N, A:N). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a free subscriber account on the target WooCommerce marketplace, then sends a crafted authenticated HTTP request to a theme-registered AJAX handler or REST endpoint that omits authorization checks. Because no capability check gates the operation, the subscriber's request is processed as if it originated from a privileged user, allowing unauthorized modification of marketplace data such as product listings, orders, or vendor settings. … |
| Remediation | Upgrade the Martfury WooCommerce Marketplace WordPress Theme beyond version 3.2.8 by consulting the Patchstack advisory (https://patchstack.com/database/wordpress/theme/martfury/vulnerability/wordpress-martfury-woocommerce-marketplace-wordpress-theme-theme-3-2-8-broken-access-control-vulnerability) for the exact patched release version - an explicit fix version was not confirmed in the available input data. … Detailed patch versions, workarounds, and compensating controls in full report. |
