    The Import and export users and customers plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Custom Column User Meta Profile Fields in all versions up to, and including, 2.4.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with custom-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

  • Sep 23, 2026Import and export users and customers: Privilege EscalationCVE-2026-86583 · WordPress plugins & themes · reported by WordfenceHigh 8.8

    The Import and export users and customers plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.4.17 via the plugin's own export and re-import workflow. The vulnerability exists because the exporter writes CSV cells using fputcsv() with a NUL byte (\0) as the escape character, while the importer parses the same file using SplFileObject::fgetcsv() with only a single delimiter argument, causing PHP's default backslash escape character to be applied instead; because the export column layout places display_name immediately before the role column and nickname immediately after, an attacker can store crafted values in those two profile fields — saved by WordPress core via the standard profile page — such that the escape mismatch causes the parser to merge the display_name cell into the role field and rebalance the column count via nickname, yielding administrator as the parsed role for their own row when it reaches the import_user function's add_role function. This makes it possible for authenticated attackers with Subscriber-level access or above to escalate their privileges to Administrator. Exploitation requires a site administrator to trig

    The Import and export users and customers plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.4.0 via the email_template_selected. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract the post_title and raw post_content of arbitrary posts regardless of status (draft, private, future, trash, password-protected) or post type (including non-public CPTs such as WooCommerce orders and internal CRM records) by enumerating post IDs. The required codection-security nonce is exposed as inline JavaScript on any wp-admin page when ?post_type=acui_email_template is appended to the URL, which is reachable by any authenticated user including Subscribers.

  • Jun 30, 2026Export User Data: Arbitrary file deletionCVE-2026-12240 · WordPress plugins & themes · reported by WordfenceHigh 8

    The Export User Data plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the unserialize function in all versions up to, and including, 2.2.6. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). Successful exploitation requires an administrator to trigger a user data export while a subscriber-level (or higher) user has stored a crafted serialized XLSXWriter object payload as their display name.

  • May 2, 2026Import and export users and customers: Privilege EscalationCVE-2026-7641 · WordPress plugins & themes · reported by WordfenceHigh 8.8

    The Import and export users and customers plugin for WordPress is vulnerable to Privilege Escalation in all versions up to and including 2.0.8 via the `save_extra_user_profile_fields()` function. This is due to an incomplete blocklist that correctly restricts capability meta keys for the primary site (e.g., `wp_capabilities`, `wp_user_level`) but fails to block the equivalent meta keys for any other subsite in a WordPress Multisite network (e.g., `wp_2_capabilities`, `wp_2_user_level`), allowing these keys to pass the `in_array()` check and be written directly to user meta via `update_user_meta()`. This makes it possible for authenticated attackers, with Subscriber-level access and above, to escalate their privileges to Administrator on any subsite within the Multisite network by submitting a crafted profile update to `/wp-admin/profile.php`. Exploitation requires that an administrator has previously imported a CSV file containing multisite-prefixed capability column headers and has enabled the 'Show fields in profile?' option, which causes those keys to be stored in the `acui_columns` option and exposed as editable fields on the user profile page.

  • Mar 21, 2026Import and export users and customers: Privilege escalationCVE-2026-3629 · WordPress plugins & themes · reported by WordfenceHigh 8.1

    The Import and export users and customers plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 1.29.7. This is due to the 'save_extra_user_profile_fields' function not properly restricting which user meta keys can be updated via profile fields. The 'get_restricted_fields' method does not include sensitive meta keys such as 'wp_capabilities'. This makes it possible for unauthenticated attackers to escalate their privileges to Administrator by submitting a crafted registration request that sets the 'wp_capabilities' meta key. The vulnerability can only be exploited if the "Show fields in profile" setting is enabled and a CSV with a wp_capabilities column header has been previously imported.
