CVE-2025-69355: Tickera Auth Bypass Vulnerability

CVE-2025-69355 Overview

CVE-2025-69355 is a Missing Authorization vulnerability (CWE-862) affecting the Tickera Event Ticketing System WordPress plugin. This broken access control flaw allows attackers to exploit incorrectly configured access control security levels, potentially enabling unauthorized actions within the plugin's functionality.

Critical Impact

Unauthorized users may be able to bypass access control mechanisms and perform privileged operations within the Tickera event ticketing system, potentially compromising ticket management and event data.

Affected Products

• Tickera Event Ticketing System WordPress Plugin versions through 3.5.6.4
• WordPress installations running vulnerable Tickera plugin versions

Technical Details for CVE-2025-69355

Vulnerability Analysis

This vulnerability stems from missing authorization checks within the Tickera WordPress plugin. The plugin fails to properly verify user permissions before allowing access to certain functionality, creating a broken access control condition. This type of vulnerability (CWE-862) occurs when an application does not perform an authorization check when an actor attempts to access a resource or perform an action.

In WordPress plugin contexts, this typically manifests when AJAX handlers, REST API endpoints, or administrative functions lack proper capability checks using functions like current_user_can(). Without these checks, authenticated users with low privileges or even unauthenticated users may be able to access functionality intended only for administrators or other privileged roles.

Root Cause

The root cause of this vulnerability is the absence of proper authorization validation in the Tickera plugin's access control logic. The plugin does not adequately verify that the requesting user has the appropriate permissions before executing privileged operations. This is a common weakness in WordPress plugins where developers may rely solely on authentication (checking if a user is logged in) rather than implementing proper authorization (checking if the logged-in user has the right to perform the specific action).

Attack Vector

An attacker can exploit this vulnerability by sending specially crafted requests to vulnerable plugin endpoints without proper authorization. Since the plugin fails to validate user capabilities, the attacker can bypass intended access restrictions. The attack requires network access to the target WordPress installation but does not necessarily require authentication depending on the specific vulnerable endpoint.

The exploitation flow involves:

1. Identifying accessible plugin endpoints that lack authorization checks
2. Crafting requests to these endpoints to perform privileged actions
3. Executing operations that should be restricted to authorized users only

Detection Methods for CVE-2025-69355

Indicators of Compromise

• Unexpected modifications to ticket data, event settings, or pricing configurations
• Unusual administrative actions in WordPress audit logs originating from non-admin users
• Anomalous HTTP requests to Tickera plugin AJAX handlers or REST endpoints
• Unauthorized ticket generation or modification patterns

Detection Strategies

• Monitor WordPress access logs for requests to Tickera plugin endpoints from unauthorized IP addresses or user sessions
• Implement file integrity monitoring on Tickera plugin files to detect any unauthorized modifications
• Review WordPress user activity logs for privilege escalation attempts or unauthorized administrative actions
• Deploy web application firewall (WAF) rules to detect and block exploitation attempts targeting known broken access control patterns

Monitoring Recommendations

• Enable comprehensive WordPress audit logging to capture all plugin-related activities
• Set up alerts for unusual patterns in ticket management operations
• Monitor for new user registrations followed by immediate privileged actions
• Implement real-time security monitoring for your WordPress installation using endpoint detection and response solutions

How to Mitigate CVE-2025-69355

Immediate Actions Required

• Update the Tickera Event Ticketing System plugin to the latest patched version immediately
• Review recent activity logs for signs of exploitation or unauthorized access
• Audit current ticket and event data for any unauthorized modifications
• Consider temporarily disabling the plugin if an update is not immediately available

Patch Information

Organizations using the Tickera Event Ticketing System WordPress plugin should update to a version newer than 3.5.6.4 that addresses this authorization bypass vulnerability. Check the official WordPress plugin repository or Tickera vendor channels for the latest security update. Review the Patchstack security advisory for additional remediation guidance.

Workarounds

• Implement additional access control at the web server level to restrict access to vulnerable plugin endpoints
• Use a WordPress security plugin with virtual patching capabilities to block exploitation attempts
• Restrict administrative access to trusted IP addresses only
• Enable WordPress two-factor authentication for all administrative accounts

# Example: Restrict access to wp-admin and plugin AJAX handlers by IP
# Add to .htaccess file in WordPress root
<Files wp-admin>
  Order Deny,Allow
  Deny from all
  Allow from 192.168.1.0/24
</Files>
