WordPress · Advanced Import · CVE-2026-4328
**Name of the Vulnerable Software and Affected Versions**
Advanced Import versions prior to 1.4.7
**Description**
Server-Side Request Forgery (SSRF) occurs when the plugin uses the `wp remote get()` function to fetch a user-supplied URL without validating that the destination does not point to internal or private network resources. This issue is located within the `demo download and unzip()` function. Specifically, when the `demo file type` is set to 'url', the `demo file` parameter from `$ POST` is processed via `sanitize text field()`—which only prevents cross-site scripting (XSS)—and passed directly to the request function. Authenticated attackers with Author-level access or higher (possessing the `upload files` capability) can leverage this to make web requests to arbitrary locations from the application, potentially querying and viewing data from internal services or cloud instance metadata endpoints.
**Recommendations**
Update to a version later than 1.4.6.
As a temporary workaround, restrict access for users with Author-level permissions or disable the `demo download and unzip()` function until the update is applied.
