CVE-2025-69327: Car Rental Manager Auth Bypass Flaw

CVE-2025-69327 Overview

CVE-2025-69327 is a Missing Authorization vulnerability affecting the Car Rental Manager WordPress plugin developed by magepeopleteam. This broken access control flaw allows authenticated attackers to exploit incorrectly configured access control security levels, potentially performing unauthorized actions within the plugin's functionality.

The vulnerability stems from inadequate authorization checks (CWE-862), which fails to properly validate whether authenticated users have the necessary permissions before granting access to protected functions or resources.

Critical Impact

Authenticated attackers with low-level privileges can bypass access controls to perform unauthorized modifications, potentially impacting data integrity within the Car Rental Manager plugin.

Affected Products

• Car Rental Manager WordPress Plugin versions through 1.0.9
• WordPress installations running vulnerable versions of the car-rental-manager plugin
• All configurations of Car Rental Manager prior to security patch

Technical Details for CVE-2025-69327

Vulnerability Analysis

This vulnerability is classified as a Broken Access Control issue, specifically a Missing Authorization vulnerability (CWE-862). The flaw exists within the Car Rental Manager WordPress plugin, which fails to implement proper authorization checks for certain plugin functionality.

When a user with valid authentication credentials (even with minimal privileges) interacts with specific plugin endpoints or functions, the application does not verify whether that user has the appropriate permission level to perform the requested action. This allows low-privileged authenticated users to execute operations that should be restricted to administrators or higher-privileged roles.

The network-accessible nature of this vulnerability means that any authenticated user with network access to the WordPress installation can potentially exploit this flaw. While the impact is limited to integrity violations (unauthorized modifications) without direct confidentiality or availability impact, this could still lead to significant issues in production environments managing rental operations.

Root Cause

The root cause of CVE-2025-69327 is the absence of proper authorization validation within the Car Rental Manager plugin's access control implementation. The plugin fails to verify user capabilities or roles before processing requests to sensitive functions, allowing authenticated users to bypass intended access restrictions.

WordPress plugins should leverage the platform's built-in capability checking functions such as current_user_can() to validate permissions before executing privileged operations. The vulnerable versions of Car Rental Manager do not adequately implement these checks.

Attack Vector

The attack vector for this vulnerability requires network access and a valid authenticated session on the target WordPress installation. An attacker must first obtain valid credentials (even subscriber-level access) to exploit this vulnerability.

Once authenticated, the attacker can access plugin functionality that should be restricted to higher-privileged users, potentially allowing them to:

• Modify rental configurations
• Access administrative plugin settings
• Make unauthorized changes to rental data

The attack does not require user interaction and can be executed with low complexity, making it relatively straightforward for an attacker with valid credentials to exploit.

Detection Methods for CVE-2025-69327

Indicators of Compromise

• Unexpected modifications to Car Rental Manager settings by non-administrative users
• Audit logs showing low-privileged users accessing administrative plugin endpoints
• Unusual AJAX requests to Car Rental Manager plugin functions from subscriber or contributor accounts
• Changes to rental data or configurations without corresponding administrator activity

Detection Strategies

• Monitor WordPress audit logs for unauthorized access attempts to Car Rental Manager administrative functions
• Implement Web Application Firewall (WAF) rules to detect and block unauthorized access patterns
• Review user activity logs for privilege escalation attempts or access control bypass indicators
• Deploy endpoint detection solutions to monitor for suspicious plugin interactions

Monitoring Recommendations

• Enable comprehensive WordPress activity logging with focus on plugin-level operations
• Configure alerts for administrative actions performed by non-administrator users
• Regularly audit user roles and capabilities within WordPress installations
• Monitor network traffic for unusual patterns targeting the car-rental-manager plugin endpoints

How to Mitigate CVE-2025-69327

Immediate Actions Required

• Audit all user accounts with access to the WordPress installation and verify appropriate role assignments
• Review recent activity logs for signs of unauthorized access or data modification
• Consider temporarily deactivating the Car Rental Manager plugin until a patched version is available
• Implement additional access controls at the web server level to restrict plugin access
• Enable WordPress audit logging if not already configured

Patch Information

Organizations should monitor the Patchstack Vulnerability Database Entry for updates regarding security patches from the plugin vendor.

Update the Car Rental Manager plugin to a version newer than 1.0.9 once a security patch is released by magepeopleteam. Verify the changelog confirms the authorization vulnerability has been addressed before upgrading.

Workarounds

• Restrict plugin access to only trusted administrator accounts until a patch is available
• Implement additional capability checks using WordPress hooks or a security plugin
• Use a Web Application Firewall to filter and block unauthorized requests to plugin endpoints
• Review and remove unnecessary user accounts with authenticated access to the WordPress installation

# WordPress CLI command to list users with authenticated access
wp user list --fields=ID,user_login,roles

# Review and update user roles as needed
wp user set-role <user_id> subscriber

# Verify installed plugin version
wp plugin list --name=car-rental-manager --fields=name,version,status
