CVE-2026-24540: Integrate Google Drive Auth Bypass Flaw

CVE-2026-24540 Overview

CVE-2026-24540 is a Missing Authorization vulnerability affecting the Integrate Google Drive WordPress plugin developed by Prince. This vulnerability allows attackers to exploit incorrectly configured access control security levels, potentially gaining unauthorized access to plugin functionality. The flaw stems from a Broken Access Control weakness (CWE-862) where proper authorization checks are not enforced.

Critical Impact

Authenticated attackers with low privileges can bypass access controls to read and modify data they should not have access to, compromising the confidentiality and integrity of Google Drive integrations.

Affected Products

• Integrate Google Drive WordPress Plugin versions up to and including 1.5.5

Technical Details for CVE-2026-24540

Vulnerability Analysis

This vulnerability exists due to missing authorization checks within the Integrate Google Drive WordPress plugin. The plugin fails to properly verify user permissions before allowing access to certain functionality, enabling authenticated users with minimal privileges to perform actions that should be restricted to higher-privileged users or administrators.

The attack can be executed over the network by any authenticated user, requiring no user interaction. While the vulnerability does not allow for complete system compromise, it enables unauthorized read and write access to protected resources, potentially exposing sensitive Google Drive integration data or allowing unauthorized modifications to plugin settings.

Root Cause

The root cause is CWE-862: Missing Authorization. The plugin does not implement proper capability checks or nonce verification for certain AJAX actions or REST API endpoints. This allows authenticated users to bypass intended access restrictions by directly calling plugin functions without the necessary permission validation.

Attack Vector

The vulnerability is exploitable over the network by authenticated WordPress users. An attacker with a low-privilege account (such as Subscriber or Contributor role) can send crafted requests to plugin endpoints that lack proper authorization checks. These requests are processed without verifying whether the user has appropriate capabilities, allowing access to functionality intended only for administrators.

The attack requires:

1. A valid WordPress account with any role
2. Knowledge of the vulnerable endpoint or function
3. The ability to send HTTP requests to the WordPress installation

Since no proof-of-concept code is publicly available, the specific exploitation details should be referenced from the Patchstack Vulnerability Report.

Detection Methods for CVE-2026-24540

Indicators of Compromise

• Unusual AJAX requests to admin-ajax.php with Integrate Google Drive plugin actions from non-administrator users
• Unexpected modifications to Google Drive plugin settings or configurations
• Access log entries showing low-privilege users interacting with plugin administrative functions
• Anomalous API calls to Google Drive originating from the WordPress installation

Detection Strategies

• Monitor WordPress AJAX and REST API logs for unauthorized access attempts to Integrate Google Drive plugin endpoints
• Implement Web Application Firewall (WAF) rules to detect and block suspicious parameter patterns associated with the plugin
• Review user activity logs for privilege boundary violations, particularly low-privilege users accessing administrative functions
• Enable verbose logging for the plugin to capture authorization failures and unusual access patterns

Monitoring Recommendations

• Configure SentinelOne to monitor for suspicious WordPress plugin activity and unauthorized file access patterns
• Set up alerts for multiple failed authorization attempts or unusual user permission escalation events
• Regularly audit WordPress user roles and permissions to ensure principle of least privilege
• Monitor outbound connections to Google APIs for unauthorized data access or exfiltration attempts

How to Mitigate CVE-2026-24540

Immediate Actions Required

• Update the Integrate Google Drive plugin to a version newer than 1.5.5 when a patched version becomes available
• Audit all user accounts and remove unnecessary low-privilege accounts that could be used for exploitation
• Review and restrict WordPress user roles to ensure only trusted users have authenticated access
• Consider temporarily disabling the plugin if Google Drive integration is not critical to operations

Patch Information

The vulnerability affects Integrate Google Drive plugin versions up to and including 1.5.5. Organizations should monitor for security updates from the plugin developer and apply patches immediately when available. For detailed vulnerability information and patch status, refer to the Patchstack Vulnerability Report.

Workarounds

• Restrict access to the WordPress admin area using IP allowlisting or VPN requirements
• Implement additional authentication layers such as two-factor authentication for all WordPress users
• Use a WordPress security plugin to add capability checks and monitor for suspicious plugin activity
• Temporarily deactivate the Integrate Google Drive plugin if a patch is not yet available and functionality is non-essential

# WordPress configuration - restrict admin access by IP
# Add to .htaccess in wp-admin directory
