Shop manager PHP Object Injection in Content Egg <= 6.3.1 versions.
AnalysisAI
PHP object injection in the WordPress plugin Content Egg through version 6.3.1 allows an attacker who holds the Shop manager role to trigger unsafe deserialization of attacker-controlled data, potentially leading to full site compromise. The vulnerability is network-reachable with low attack complexity and requires no user interaction, but the PR:H rating in the CVSS vector means a valid authenticated account at the Shop manager privilege level is a prerequisite, and meaningful code-execution impact further depends on the presence of a usable PHP POP gadget chain in Content Egg or another loaded plugin or theme. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires an authenticated WordPress account with the Shop manager role (PR:H) on a site running Content Egg plugin version 6.3.1 or earlier; this is a WooCommerce-oriented management role, so the site typically must have WooCommerce/e-commerce functionality with delegated shop-manager users. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score is 7.2 (High) with vector AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H, meaning network-reachable, low-complexity, no user interaction, but requiring high privileges (PR:H). … 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 version is confirmed in the available data, so administrators should treat every Content Egg release up to and including 6.3.1 as vulnerable and check the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/content-egg/vulnerability/wordpress-content-egg-plugin-6-3-1-php-object-injection-vulnerability?_s_id=cve) plus the plugin's WordPress.org changelog for a fixed release before assuming a given version is safe; absence of a documented fix in this data set is not evidence that none exists. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all WordPress instances running Content Egg 6.3.1 or earlier, immediately deactivate and remove the plugin where feasible, and audit all Shop manager accounts for necessity and suspicious activity. …
