CVE-2026-19728 WordPress CVE debrief

The Extra Product Options Builder for WooCommerce WordPress plugin before 1.2.176 does not verify that the requester is entitled to a customer-uploaded file before serving it, allowing unauthenticated users who obtain a file's stored name to retrieve it. The Extra Product Options Builder for WooCommerce WordPress plugin before 1.2.176 writes a deny-all rule into its upload directories, so the disclosure only crosses a boundary on web servers that honour it, such as Apache. Where it is ignored, as on a default nginx setup, the same files are already served at their direct URL and the endpoint exposes nothing further.

Who should care

Administrators and security teams responsible for WordPress and WooCommerce installations, especially those using the Extra Product Options Builder plugin, should be aware of this vulnerability and take steps to mitigate it.

Technical summary

The Extra Product Options Builder for WooCommerce WordPress plugin before 1.2.176 does not verify that the requester is entitled to a customer-uploaded file before serving it. This allows unauthenticated users who obtain a file's stored name to retrieve it. The plugin writes a deny-all rule into its upload directories, but this only affects web servers like Apache that honor such rules. On servers like nginx with default settings, these files are already served directly and the endpoint does not expose additional information.

Defensive priority

CVE-2026-19728 is rated HIGH with a CVSS score of 7.5. Consider verifying the entitlement checks for customer-uploaded files in the Extra Product Options Builder for WooCommerce WordPress plugin.

Recommended defensive actions
