Critical Insights on the Broken Access Control Vulnerability in “Simple Bike Rental” (≤ 1.0.6) — How Managed-WP Safeguards Your WordPress Site
作者： 託管 WordPress 安全團隊
日期： 2025-12-12
執行摘要
A significant broken access control vulnerability was discovered in the WordPress plugin Simple Bike Rental (versions up to and including 1.0.6). Authenticated users with the Subscriber role or higher could improperly access booking information that should have remained private. This vulnerability, tracked as CVE‑2025‑14065, has been addressed in version 1.0.7.
While the overall severity is rated low (CVSS 5.3) because it requires authenticated access, the potential exposure of personally identifiable information (PII), such as names, contact details, and booking timestamps, creates privacy and compliance risks.
If you manage WordPress sites using this plugin, we strongly advise you to:
- Immediately update Simple Bike Rental to version 1.0.7 or higher.
- Implement mitigation measures such as role hardening and firewall-level virtual patching if immediate updating isn’t feasible.
- Consider deploying a managed Web Application Firewall (WAF) like Managed-WP to enforce customized access controls and rapid virtual patching.
This advisory aims to equip site owners and developers with an authoritative explanation of the risk, detection guidance, and practical remediation steps, informed by leading US cybersecurity expertise.
本諮詢的目的
This communication is issued by Managed-WP, a trusted WordPress security partner specializing in managed firewall services and vulnerability response. Our objective is to provide site operators with clear, actionable intelligence on emergent threats, ensuring they can act decisively to minimize exposure without amplifying risk by revealing exploit vectors.
漏洞概述
- 軟體: Simple Bike Rental WordPress plugin
- 受影響版本： 1.0.6 and earlier
- 已修復版本： 1.0.7
- 漏洞類型： Broken Access Control (missing authorization checks)
- 所需存取等級： Authenticated user with Subscriber role or above
- CVE標識符： CVE-2025-14065
- 嚴重程度： Low (CVSS score 5.3)
- 報道人： Athiwat Tiprasaharn (Jitlada)
This flaw stems from an endpoint that exposes booking data without verifying if the requesting user has rights to access it. The patch adds necessary authorization validations to ensure that booking details are only accessible by rightful owners or administrators.
The Real-World Implications for Site Owners
Despite requiring an authenticated account, the vulnerability’s implications are non-trivial due to:
- Sites that permit public user registration, enabling attackers to create Subscriber accounts and exploit the flaw.
- The sensitive nature of booking data, which often includes PII such as customer names, contact info, dates, and payment references—exposure could trigger privacy violations and regulatory penalties.
- Potential for attackers to harvest and aggregate booking information at scale, facilitating further abuse.
- Indirect risks if booking metadata contains internal IDs useful for targeting related systems (e.g., customer service).
Even vulnerabilities rated as low severity must be taken seriously when attackers can leverage automation and volume.
Technical Summary (Without Exploit Disclosure)
- The flaw is classic broken access control: the plugin’s data-sharing endpoint fails to verify that users own the booking data they request.
- Basic authentication checks (e.g.,
is_user_logged_in()) are insufficient without verifying user capabilities or ownership. - Authorization checks should include use of
當前使用者可以（）and ownership comparisons. - REST API endpoints require a
權限回調function enforcing access controls before data retrieval.
Below is an example of proper authorization pattern for PHP handlers within WordPress:
// Example authorization pattern
if ( ! is_user_logged_in() ) {
wp_send_json_error( 'login_required', 401 );
}
$current_user_id = get_current_user_id();
if ( $booking->user_id !== $current_user_id && ! current_user_can( 'manage_options' ) ) {
wp_send_json_error( 'forbidden', 403 );
}
// Return booking data safely
REST API implementations should similarly verify permissions via 權限回調.
Exploitability Perspective
- Attackers must hold Subscriber-level authenticated access, which is trivial to obtain on sites allowing open registration.
- Sites without public registration face reduced but not zero risk, depending on role assignments.
- Automated scraping is enabled by the lack of proper access controls on data endpoints.
Risk assessment depends heavily on site policies around user registration and monitoring controls.
Immediate Action Plan (Within 24 Hours)
- Upgrade Simple Bike Rental to version 1.0.7+ immediately — this closes the authorization gap.
- If update is delayed, disable the plugin temporarily or block affected endpoints.
- Harden user registration flows:
- Disable public registrations unless necessary.
- Implement email verification and/or manual approval workflows.
- Restrict booking data access for Subscribers where feasible.
- Audit logs for suspicious activity:
- Unusual or repetitive requests to booking endpoints.
- Multiple new Subscriber accounts followed by data access.
- Rotate or revoke any exposed sensitive credentials if a breach is suspected.
- Apply firewall-level mitigations or virtual patches to block unauthorized access temporarily.
If you are Managed-WP client, these protections can be deployed instantly by our team while you update your plugin.
Medium-Term Remediation (24 Hours to 2 Weeks)
- Adopt least-privilege principles — audit roles and capabilities, removing unnecessary permissions.
- Enhance monitoring and alerting for access to sensitive booking resources.
- Strengthen user authentication and verification (such as multi-factor or payment confirmation) for booking-related accounts.
- Log data access events for incident response readiness.
- Review custom code and third-party hooks to ensure consistent access controls.
Role of a WAF in Mitigating This Vulnerability
A Web Application Firewall supplements plugin fixes by providing:
- Rapid virtual patching: blocking exploit attempts without waiting for plugin upgrades.
- Rate-limiting access to prevent scraping and abuse.
- Heuristic-based blocking of suspicious user accounts and IP addresses.
- Real-time alerts on anomalous traffic patterns targeting booking data.
However, a WAF cannot replace proper authorization logic in the plugin and cannot prevent abuse of legitimate compromised accounts on its own.
Managed-WP delivers tailored virtual patches and customized rulesets that provide immediate protection during your remediation window.
檢測指標
Monitor logs for:
- High volume requests to the plugin’s booking endpoints.
- Multiple authenticated Subscriber accounts accessing booking data that does not belong to them.
- Suspicious account creation IP addresses and access patterns.
- Requests lacking expected security tokens (nonces) where applicable.
If suspicious activity is found:
- Extract and preserve logs for forensic analysis.
- Temporarily suspend offending accounts pending investigation.
- Notify affected users if sensitive data exposure occurred, in compliance with legal obligations.
Comprehensive Remediation Checklist for Developers and Operators
致插件開發者：
- Implement strict capability and ownership checks for all relevant endpoints.
- 使用
當前使用者可以（）and validate object ownership (get_current_user_id()) before returning sensitive data. - For REST API routes, utilize the
權限回調parameter effectively. - Enforce nonce verification for AJAX and stateful interactions.
- Create thorough unit and integration tests covering access control paths.
- Log access to sensitive data for auditing purposes.
For Site Owners/Administrators:
- Maintain up-to-date plugins and themes.
- Audit and enforce least privilege for all user roles.
- Deploy managed WAF solutions offering real-time virtual patching.
- Establish monitoring and incident response protocols.
Developer Guidance: Example Authorization Patterns
REST Endpoint with Permission Callback
register_rest_route( 'sbr/v1', '/bookings/(?P<id>\d+)', array(
'methods' => 'GET',
'callback' => 'sbr_get_booking',
'permission_callback' => function( $request ) {
$user = wp_get_current_user();
if ( $user->ID === 0 ) {
return new WP_Error( 'rest_not_logged_in', 'You must be logged in.', array( 'status' => 401 ) );
}
$booking_id = intval( $request['id'] );
$booking = sbr_get_booking_by_id( $booking_id );
if ( ! $booking ) {
return new WP_Error( 'rest_booking_not_found', 'Booking not found.', array( 'status' => 404 ) );
}
if ( $booking->user_id !== $user->ID && ! user_can( $user, 'manage_options' ) ) {
return new WP_Error( 'rest_forbidden', 'You are not allowed to view this booking.', array( 'status' => 403 ) );
}
return true;
}
) );
AJAX Action with Capability Check
add_action( 'wp_ajax_sbr_get_booking', 'handle_sbr_get_booking' );
function handle_sbr_get_booking() {
if ( ! is_user_logged_in() ) {
wp_send_json_error( 'login_required', 401 );
}
check_ajax_referer( 'sbr_nonce', 'security' );
$booking_id = intval( $_POST['id'] );
$booking = sbr_get_booking_by_id( $booking_id );
if ( ! $booking ) {
wp_send_json_error( 'not_found', 404 );
}
if ( $booking->user_id !== get_current_user_id() && ! current_user_can( 'manage_options' ) ) {
wp_send_json_error( 'forbidden', 403 );
}
wp_send_json_success( $booking );
}
These patterns enforce that only authorized users can retrieve sensitive booking data, effectively mitigating access control vulnerabilities.
Incident Response Recommendations if Breached
- Contain the Threat: Disable or update the vulnerable plugin immediately, suspend suspicious accounts, block offending IPs, and throttle traffic.
- Investigate Thoroughly: Collect and analyze server, plugin, and WAF logs to determine breach scope and affected data.
- 補救措施： Patch plugin to 1.0.7 or later, rotate credentials and API keys, reset affected user passwords.
- Notify Affected Parties: Inform impacted users with clear details and remediation instructions—comply with legal data breach notifications.
- Learn and Improve: Perform root cause analysis and enhance development and security practices to prevent recurrence.
Why Timely Updates Are Crucial
Attackers rapidly scan sites for vulnerable plugin versions post-disclosure. Prompt patching removes exploitable conditions from your environment permanently. For large site fleets, automation and staged rollouts can preserve stability while prioritizing security patches.
Common False Protection Patterns to Avoid
- Assuming UI-level hiding (CSS/JS) suffices to protect sensitive data.
- Relying solely on nonces for GET requests or data retrieval endpoints.
- Placing access controls only in front-end templates rather than server-side handlers.
Robust, server-side authorization checks are mandatory.
