Overview
CVE-2025-66072 describes a Missing Authorization vulnerability found in the Stiofan UsersWP plugin for WordPress. Specifically, it allows for the exploitation of incorrectly configured access control security levels. This vulnerability affects UsersWP versions from n/a through 1.2.47. A successful exploit could allow unauthorized users to access or modify sensitive data or perform actions they should not be permitted to do.
Technical Details
The core issue lies in the plugin’s insufficient validation of user roles and permissions before granting access to certain functionalities or data. This “Broken Access Control” (as described in the Patchstack vulnerability database) means that a user with a lower privilege level can potentially bypass authorization checks and perform actions intended only for administrators or higher-level users.
While specific exploitation details are not provided here, the general nature of a missing authorization vulnerability means an attacker could potentially manipulate requests or directly access privileged functions without proper authentication. This typically involves crafting malicious requests to bypass access control checks performed by the plugin.
CVSS Analysis
Currently, the CVE entry indicates that the Severity and CVSS Score are N/A. This likely means the vulnerability is newly discovered and awaiting formal scoring. However, based on the description of a missing authorization leading to potential data access and modification, it is likely to receive a MEDIUM to HIGH severity score once assessed. Keep an eye on the official CVE entry for updates.
Possible Impact
The potential impact of exploiting this vulnerability is significant. Depending on the specific functions affected, consequences could include:
- Unauthorized Access to User Data: Attackers could gain access to user profiles, potentially including sensitive information like email addresses, personal details, and private messages.
- Account Takeover: In some scenarios, attackers might be able to elevate their privileges or modify user accounts, leading to complete account takeover.
- Data Manipulation: Attackers could modify or delete user data, leading to data corruption or loss.
- Website Defacement or Compromise: If administrative functions are accessible, an attacker could potentially deface the website, inject malicious code, or completely compromise the entire WordPress installation.
Mitigation and Patch Steps
The primary mitigation step is to immediately update the UsersWP plugin to the latest available version. If a version higher than 1.2.47 is available, it likely contains a patch addressing this vulnerability. Follow these steps:
- Log in to your WordPress admin dashboard.
- Navigate to “Plugins” -> “Installed Plugins.”
- Locate the “UsersWP” plugin in the list.
- If an update is available, click the “Update Now” button.
If an update is not yet available, monitor the UsersWP plugin page on WordPress.org and the Patchstack vulnerability database for updates. Consider temporarily disabling the plugin until a patch is released if the risk is deemed too high for your environment.
