CVE-2026-75971 roxnor CVE debrief

Who should care

Defenders responsible for WordPress installations with the ShopEngine Elementor WooCommerce Builder Addon – All in One WooCommerce Solution plugin, particularly those with Shop Manager-level users, should assess exposure and prioritize verification.

Why it matters

CVE-2026-75971 allows authenticated attackers with Shop Manager-level access to escalate privileges and potentially take over a WordPress site by modifying arbitrary options.

• Enabling open self-registration of Administrator accounts
• Full site takeover through arbitrary WordPress option modification
• Elevation of privileges for authenticated attackers with Shop Manager-level access

Technical summary

The `rum_importer()` function is registered on the WordPress core `import_start` action hook with no plugin-owned capability check and no allowlist filtering, allowing arbitrary `<wp_option>` name/value pairs to be passed directly to `update_option()`. This makes it possible for authenticated attackers, with Shop Manager-level access and above, to write arbitrary WordPress options — most critically setting `users_can_register` to `1` and `default_role` to `administrator` — enabling open self-registration of Administrator accounts and full site takeover. The vulnerability allows authenticated attackers, with Shop Manager-level access and above, to write arbitrary WordPress options.

Defensive priority

Defenders should prioritize verifying exposure of ShopEngine Elementor WooCommerce Builder Addon versions up to 4.9.4 and assessing the role of Shop Manager-level users.

Recommended defensive actions

• Verify exposure of ShopEngine Elementor WooCommerce Builder Addon versions up to 4.9.4
• Assess the role of Shop Manager-level users

• Monitor for suspicious activity related to the `import_start` hook
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented

Evidence notes

The vulnerability allows authenticated attackers, with Shop Manager-level access and above, to write arbitrary WordPress options — most critically setting `users_can_register` to `1` and `default_role` to `administrator` — enabling open self-registration of Administrator accounts and full site takeover.
