WP Import Export Lite vulnerabilities

The WP Import Export Lite WordPress plugin before 3.9.35 does not verify that the user running an import is permitted to create or modify user accounts and assign roles, allowing users granted a delegated WP Import Export Lite WordPress plugin before 3.9.35 permission, who cannot otherwise manage users, to create administrator accounts and to overwrite the credentials and role of existing accounts, including administrators.

The WP Import Export Lite plugin before 3.9.33 does not properly validate URLs before requesting them during the import process, allowing users with import capability (administrators by default) to make the site issue requests to internal hosts and services and read their responses. This is an incomplete fix for CVE-2026-11397.

The WP Import Export Lite plugin before 3.9.33 does not escape custom field names retrieved from the database before inserting them into the DOM of one of its administration screens, allowing users with a role as low as contributor to perform Stored XSS attacks which will trigger in the browser of a high privileged user, such as an administrator, viewing that screen.

The WP Import Export Lite plugin before 3.9.33 does not properly sanitise and escape some import configuration values before using them in SQL statements, allowing users whose role an administrator has granted the import permission to perform SQL injection attacks.

The WP Import Export Lite plugin before 3.9.33 does not properly sanitise and escape some export filter values before using them in SQL statements, allowing users holding its export permission (administrators by default, may also grant to lower roles) to perform SQL injection attacks.

The WP Import Export Lite WordPress plugin before 3.9.33 does not validate a user-supplied file path before reading it and copying it into a publicly accessible directory, allowing users with import permission to disclose sensitive files from the server, including files outside the web root. The same code path also relaxes file-system permissions of any path it is given, whether or not the copy succeeds.

The WP Import Export Lite WordPress plugin before 3.9.33 does not validate a path taken from stored, user-supplied data before recursively deleting the directory it resolves to, allowing users to whom an administrator has delegated a capability to delete arbitrary directories and every file within them, including outside the web root.

The WP Import Export Lite WordPress plugin before 3.9.33 does not validate the type, extension or content of files it retrieves from a user-supplied URL during import, allowing users granted its import permission to store arbitrary files, including executable ones, on the server and achieve remote code execution.

The WP Import Export Lite WordPress plugin before 3.9.33 does not restrict which PHP function may be applied to exported field values, allowing users granted its export permission to have arbitrary functions invoked on values they control, leading to remote code execution.

The WP Import Export Lite WordPress plugin before 3.9.34 does not validate a user-supplied output path when writing export files, allowing users granted its export permission to write files with arbitrary names to arbitrary locations on the server, leading to remote code execution.

The WP Import Export Lite plugin for WordPress is vulnerable to Server-Side Request Forgery (SSRF) in all versions up to and including 3.9.30 via the wpie_import_upload_file_from_url AJAX action. After wp_safe_remote_get() fails (blocking private IPs), the plugin falls back to GuzzleHttp\Client::request() with no SSRF protection and disabled TLS verification. This allows authenticated attackers with administrator-level access to make requests to arbitrary internal services, such as cloud metadata endpoints.
