CVE-2025-31752

Vulnerability

The Bulk Fields Editor plugin (bulk-user-editor) for WordPress versions from n/a through 1.8.0 contains a missing authorization vulnerability. The plugin provides bulk editing capabilities for user meta fields, post and custom post type categories, and Gravity Forms entries. The vulnerability lies in the failure to properly verify user permissions before allowing access to these bulk editing functions. This allows users with insufficient privileges to perform actions that should be restricted to higher-level roles such as administrators. The affected versions are all versions up to and including 1.8.0, as per the plugin's changelog and the CVE description [1].

Exploitation

An attacker needs to have a valid user account on the WordPress site, but not necessarily with administrative privileges. The attacker can access the bulk editing interfaces (e.g., "Bulk Edit Users" under Users menu, "Bulk Edit Posts" under Posts menu, or "Bulk Edit Fields" under Gravity Forms submenu) without proper authorization checks. By navigating to these pages, the attacker can perform bulk operations such as modifying user meta fields, changing post categories, or editing Gravity Forms entries. No special authentication or network position is required beyond being a logged-in user. The exploitation does not require any user interaction from the victim.

Impact

Successful exploitation allows an attacker to perform unauthorized bulk modifications to user metadata, post categories, and Gravity Forms entries. This can lead to data integrity issues, such as altering user profiles, changing post classifications, or corrupting form data. The attacker gains the ability to modify data that should be protected by role-based access controls. The scope of compromise is limited to the plugin's functionality, but it could be used to escalate privileges or disrupt site operations depending on the specific modifications made.

Mitigation

As of the publication date (2025-04-01), no patched version of the Bulk Fields Editor plugin has been released. The plugin was last updated on 2020-02-15 and appears to be abandoned. The recommended mitigation is to disable and remove the plugin from any WordPress installation until a security update is provided. There is no known workaround. The vulnerability is not listed in CISA's Known Exploited Vulnerabilities catalog as of this writing.
