Overview
CVE-2025-12392 is a medium-severity security vulnerability affecting the Cryptocurrency Payment Gateway for WooCommerce plugin for WordPress. This vulnerability allows unauthenticated attackers to modify user tracking preferences (opt-in/opt-out) due to a missing capability check in the ‘handle_optin_optout’ function. All versions up to, and including, 2.0.22 are affected.
Technical Details
The vulnerability resides within the handle_optin_optout function of the plugin. Specifically, the function lacks proper authorization checks to verify if the user initiating the request has the necessary capabilities to modify tracking settings. As a result, an unauthenticated attacker can craft a malicious request to either opt-in or opt-out a user from tracking, potentially impacting data privacy and analysis derived from tracking user behavior.
The vulnerable code does not check for proper WordPress capabilities before executing the opt-in/opt-out logic. This missing check is what allows unauthorized access.
CVSS Analysis
- CVSS Score: 5.3 (Medium)
- Vector: AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
This score reflects the ease of exploitation (no authentication required), the limited scope of the impact (only affecting tracking preferences), and the potential for unauthorized modification of data.
Possible Impact
Successful exploitation of this vulnerability could have several negative consequences:
- Incorrect Tracking Data: Attackers can manipulate tracking data, leading to inaccurate reports and flawed analysis of user behavior.
- Privacy Concerns: Users might unknowingly be opted into tracking without their consent, raising privacy concerns and potentially violating data protection regulations.
- Reputational Damage: If the vulnerability is widely exploited, it could damage the reputation of the website using the affected plugin.
Mitigation or Patch Steps
The recommended course of action is to update the Cryptocurrency Payment Gateway for WooCommerce plugin to the latest version. Versions greater than 2.0.22 include a fix that implements the necessary capability checks, preventing unauthorized access to the handle_optin_optout function.
To update the plugin:
- Log in to your WordPress administration dashboard.
- Navigate to the “Plugins” section.
- Locate the “Cryptocurrency Payment Gateway for WooCommerce” plugin.
- If an update is available, click the “Update Now” button.
If an update is not yet available, consider temporarily disabling the plugin until a patched version is released.
