Remediation/Mitigation Strategy for CVE-2025-32695

Vulnerability: Incorrect Privilege Assignment

Description: The Mestres do WP Checkout Mestres WP plugin, in versions up to and including 8.7.5, contains an Incorrect Privilege Assignment vulnerability. This allows an attacker to escalate their privileges within the WordPress environment.

Severity: Critical (CVSS Score: 9.8)

Known Exploit: Due to the privilege escalation nature of this vulnerability, a successful exploit would allow an attacker to perform actions reserved for higher-level users, potentially including:

  • Modifying website content
  • Installing malicious plugins or themes
  • Creating new administrative users
  • Accessing sensitive data (customer information, payment details, etc.)
  • Full control of the website

Remediation:

  1. Immediate Update: Update the Mestres do WP Checkout Mestres WP plugin to a version higher than 8.7.5. The developers have likely released a patch addressing this vulnerability. Check the official Mestres do WP website or the WordPress plugin repository for the updated version.
  2. Verification: After updating, verify the installation was successful and confirm that the updated plugin version is running.
  3. User Role Audit: Review existing user roles and permissions within your WordPress installation. Ensure that users have the appropriate level of access based on their responsibilities. Remove any unnecessary or excessive privileges.
  4. Principle of Least Privilege: Apply the principle of least privilege. Grant users only the minimum level of access required to perform their tasks.
  5. Security Hardening: Implement general WordPress security best practices to further harden your site against potential attacks. This includes:
    • Using strong, unique passwords for all user accounts.
    • Enabling two-factor authentication (2FA).
    • Regularly updating WordPress core, themes, and plugins.
    • Using a web application firewall (WAF).
    • Monitoring website activity for suspicious behavior.

Mitigation:

  1. Disable the Plugin: If an immediate update is not possible, temporarily disable the Mestres do WP Checkout Mestres WP plugin. This will prevent exploitation of the vulnerability until a patch can be applied.
  2. Web Application Firewall (WAF) Rules: If you have a WAF, configure rules to detect and block potential privilege escalation attempts targeting the Mestres do WP Checkout Mestres WP plugin. Consult your WAF vendor for specific guidance.
  3. Monitor Logs: Closely monitor WordPress and server logs for any suspicious activity related to privilege escalation, particularly actions performed by users with lower-level roles.
  4. Incident Response Plan: Develop or review your incident response plan to ensure that you are prepared to respond effectively in the event of a successful exploit. This includes steps for isolating the affected system, containing the damage, and restoring functionality.
