CVE-2026-107425: Bus Ticket Booking Authorization Bypass

CVE-2026-107425 Overview

CVE-2026-107425 is a Missing Authorization vulnerability [CWE-862] in the Magepeople Bus Ticket Booking with Seat Reservation WordPress plugin. The flaw stems from incorrectly configured access control security levels, allowing unauthenticated attackers to reach plugin functionality that should require authorization. The issue affects all plugin versions up through 5.9.7. Successful exploitation can modify data and degrade availability without any user interaction.

Critical Impact

Unauthenticated network attackers can abuse exposed plugin endpoints to tamper with booking data and disrupt plugin availability on affected WordPress sites.

Affected Products

• Magepeople Bus Ticket Booking with Seat Reservation WordPress plugin
• All versions from n/a through 5.9.7
• WordPress sites running the bus-ticket-booking-with-seat-reservation plugin

Technical Details for CVE-2026-107425

Vulnerability Analysis

The plugin exposes functionality without enforcing proper authorization checks on sensitive actions. Missing Authorization [CWE-862] occurs when code performs a security-relevant action but fails to verify the requesting user has the required capability or role. In this plugin, affected handlers do not confirm the caller is permitted before processing requests. Attackers can therefore invoke protected actions directly over the network.

The scope of impact aligns with limited integrity and availability consequences, with no direct confidentiality loss. See the Patchstack Vulnerability Report for additional technical context.

Root Cause

The root cause is broken access control in request handlers. The plugin registers endpoints — likely through WordPress AJAX actions such as wp_ajax_nopriv_* or REST routes — without a corresponding current_user_can() capability check or nonce validation. This gap allows unauthenticated requests to invoke privileged logic.

Attack Vector

An attacker sends crafted HTTP requests directly to the vulnerable plugin endpoints. No authentication, privileges, or user interaction are required. The attacker can trigger booking-related actions, alter reservation state, or cause plugin operations to fail. No verified public exploit or proof-of-concept code is currently published for this issue.

Detection Methods for CVE-2026-107425

Indicators of Compromise

• Unexpected modifications to bus booking records, seat reservations, or plugin configuration tables in the WordPress database.
• Anonymous POST requests to /wp-admin/admin-ajax.php or plugin-specific REST routes referencing bus-ticket-booking-with-seat-reservation actions.
• Spikes in HTTP 200 responses on plugin endpoints from unauthenticated sessions.

Detection Strategies

• Review web server access logs for requests to plugin endpoints lacking valid session cookies or authentication headers.
• Inspect WordPress audit logs for state changes to bookings performed by anonymous or unexpected users.
• Correlate database write events on plugin tables against the originating HTTP request identity.

Monitoring Recommendations

• Enable verbose logging on the WordPress REST API and admin-ajax.php endpoints.
• Alert on high-volume requests to plugin paths from a single source IP or ASN.
• Monitor file integrity on plugin directories to detect tampering or malicious extensions.

How to Mitigate CVE-2026-107425

Immediate Actions Required

• Identify all WordPress instances running the Bus Ticket Booking with Seat Reservation plugin at version 5.9.7 or earlier.
• Deactivate the plugin on affected sites until a vendor-fixed version is installed.
• Restrict access to /wp-admin/admin-ajax.php and plugin REST routes using a Web Application Firewall (WAF) rule that enforces authentication.
• Review recent booking data for unauthorized changes and restore from clean backups where tampering is confirmed.

Patch Information

At the time of publication, consult the Patchstack Vulnerability Report for the latest fixed version and vendor guidance. Upgrade to a release later than 5.9.7 once published by Magepeople.

Workarounds

• Use a WAF rule to block unauthenticated requests to plugin AJAX actions and REST endpoints.
• Apply virtual patching via a security plugin that enforces capability checks on the affected handlers.
• Limit site exposure by placing the WordPress admin interface behind an IP allowlist or VPN.

# Example WAF rule concept: block unauthenticated POSTs to the vulnerable plugin AJAX actions
# ModSecurity-style pseudo-rule
SecRule REQUEST_URI "@contains /wp-admin/admin-ajax.php" \
  "chain,deny,status:403,id:1072026,msg:'Block unauth access to bus-ticket plugin actions'"
  SecRule ARGS:action "@rx ^(mp_bus_|bus_ticket_)" \
    "chain"
    SecRule &REQUEST_COOKIES:/^wordpress_logged_in_/ "@eq 0"
