Severity by source
AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Network-reachable with low complexity, but the 'Custom role' requirement forces PR:H; full CIA impact reflects RCE potential of PHP Object Injection assuming a reachable gadget chain.

Custom role PHP Object Injection in eCommerce Product Catalog <= 3.6.0 versions.
AnalysisAI
PHP object injection in the Implecode eCommerce Product Catalog plugin for WordPress (3.6.0 and earlier) allows an authenticated attacker holding a high-privilege custom role to feed crafted serialized data into PHP's unserialize(), enabling arbitrary object instantiation that can escalate to remote code execution where a usable POP gadget chain exists in loaded code. Rated CVSS 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H), it carries full confidentiality, integrity and availability impact, but is access-gated: the high-privilege custom role requirement (PR:H) means anonymous and low-privileged users cannot reach the vulnerable path, so this is a genuine but access-gated risk rather than an internet-wide exposure. …

Vulnerability AssessmentAI
| Exploitation | Requires the eCommerce Product Catalog plugin (Implecode) at version 3.6.0 or earlier on WordPress, AND an authenticated actor holding a high-privilege custom role (per PR:H and the 'Custom role' description) who can reach the vulnerable deserialization input. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but access-gated risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch identified at time of analysis, so the first action is to check the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/ecommerce-product-catalog/vulnerability/wordpress-ecommerce-product-catalog-plugin-3-6-0-php-object-injection-vulnerability?_s_id=cve and the plugin's WordPress.org page for a fixed release, then upgrade to the first version above 3.6.0 as soon as it is published. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory every WordPress instance running the Implecode eCommerce Product Catalog plugin at version 3.6.0 or earlier and confirm exactly which accounts hold the high-privilege custom role that can reach the vulnerable code path; if the plugin is not business-critical, deactivate and remove it immediately, and if it must stay online, tighten role assignments to the smallest possible set of trusted administrators and add a WAF rule or managed virtual patch that blocks serialized-object payloads to the plugin's endpoints. …
