CVE-2025-69348: Events Calendar Countdown Auth Bypass

CVE-2025-69348 Overview

A Missing Authorization vulnerability has been identified in CoolHappy's "The Events Calendar Countdown Addon" WordPress plugin (countdown-for-the-events-calendar). This vulnerability allows attackers to exploit incorrectly configured access control security levels, potentially enabling unauthorized access to plugin functionality. The flaw stems from missing authorization checks (CWE-862) that fail to properly validate user permissions before allowing access to sensitive operations.

Critical Impact

Authenticated attackers with low privileges can bypass access controls to read or modify data they should not have access to, potentially compromising site integrity and confidentiality.

Affected Products

• The Events Calendar Countdown Addon versions up to and including 1.4.15
• WordPress installations using the countdown-for-the-events-calendar plugin

Technical Details for CVE-2025-69348

Vulnerability Analysis

This vulnerability is classified as a Broken Access Control issue (CWE-862: Missing Authorization). The plugin fails to implement proper authorization checks before allowing users to perform certain actions. When users interact with the plugin's functionality, the code does not verify whether the requesting user has the appropriate permissions to execute the requested operation.

The vulnerability requires network access and low-level authenticated access to exploit, meaning an attacker would need at least a subscriber or contributor role on the WordPress site. Once authenticated, the attacker can leverage the missing authorization checks to access or modify countdown configurations and potentially other plugin data that should be restricted to administrators.

Root Cause

The root cause is the absence of capability checks within the plugin's AJAX handlers or action hooks. WordPress plugins should verify user capabilities using functions like current_user_can() before processing requests that could affect site data or configurations. The countdown-for-the-events-calendar plugin versions through 1.4.15 fail to implement these critical authorization checks, allowing any authenticated user to interact with functionality intended only for higher-privileged users.

Attack Vector

The attack vector is network-based, requiring the attacker to have low-privileged authenticated access to the WordPress installation. The exploitation follows this general pattern:

1. Attacker authenticates to the WordPress site with a low-privilege account (subscriber, contributor)
2. Attacker identifies the vulnerable plugin endpoints or AJAX actions
3. Attacker crafts requests to these endpoints, bypassing the intended access restrictions
4. The plugin processes the requests without verifying user capabilities
5. Attacker successfully reads or modifies data intended for administrators only

The vulnerability can be exploited to access plugin settings, modify countdown configurations, or potentially escalate privileges depending on the specific functionality exposed through the vulnerable endpoints.

Detection Methods for CVE-2025-69348

Indicators of Compromise

• Unusual AJAX requests to countdown-for-the-events-calendar plugin endpoints from low-privilege user accounts
• Unexpected modifications to countdown settings or configurations by non-admin users
• WordPress audit logs showing plugin-related actions performed by unauthorized user roles
• Anomalous activity patterns from authenticated users accessing admin-only plugin functionality

Detection Strategies

• Implement WordPress audit logging to track all plugin-related AJAX requests and user actions
• Monitor for requests to plugin endpoints from users without appropriate administrative capabilities
• Review access logs for unusual patterns of plugin interaction from subscriber or contributor accounts
• Deploy web application firewall (WAF) rules to detect and alert on potential access control bypass attempts

Monitoring Recommendations

• Enable comprehensive logging for all WordPress AJAX actions related to the countdown plugin
• Set up alerts for any plugin setting modifications by non-administrator users
• Regularly review user activity logs for anomalous access patterns
• Monitor for failed authorization attempts that may indicate reconnaissance activity

How to Mitigate CVE-2025-69348

Immediate Actions Required

• Audit current plugin configurations and settings for any unauthorized modifications
• Review user accounts and their assigned roles, removing unnecessary elevated privileges
• Consider temporarily deactivating the countdown-for-the-events-calendar plugin until a patched version is available
• Implement additional access controls at the web server or WAF level to restrict plugin endpoint access

Patch Information

Organizations should monitor the Patchstack Vulnerability Database Entry for updates regarding a patched version. Update to a version higher than 1.4.15 when a security fix becomes available from the plugin developer CoolHappy.

Workarounds

• Restrict user registration on the WordPress site to minimize the number of authenticated accounts that could potentially exploit this vulnerability
• Implement capability-based access controls using a security plugin to add additional authorization layers
• Use a WordPress security plugin to monitor and restrict AJAX endpoint access based on user roles
• Review and harden user role permissions, ensuring subscribers and contributors have minimal capabilities
