CVE-2024-24832 Overview
CVE-2024-24832 is a Missing Authorization vulnerability in the Metagauss EventPrime plugin for WordPress. The flaw affects all versions of EventPrime from initial release through 3.3.9. The plugin fails to enforce proper authorization checks on certain functions, allowing unauthenticated network attackers to perform actions that should require elevated privileges. The weakness is categorized under [CWE-862] Missing Authorization. EventPrime is an event calendar and management plugin used by WordPress site operators to schedule and manage events.
Critical Impact
Unauthenticated attackers can modify protected plugin data over the network without any user interaction, compromising integrity of EventPrime-managed content.
Affected Products
- Metagauss EventPrime plugin for WordPress
- EventPrime versions from initial release through 3.3.9
- WordPress sites running the EventPrime event calendar and management extension

Technical Details for CVE-2024-24832
Vulnerability Analysis
The vulnerability stems from missing authorization checks in the EventPrime plugin. The plugin exposes functionality that should validate user permissions before execution, but the access control logic is absent or insufficient. Attackers can reach the affected endpoints over the network without authentication or user interaction. Successful exploitation results in unauthorized modification of plugin-managed data, impacting the integrity of event records and related configuration. The vulnerability does not require any prior privileges, which broadens the attacker population to any unauthenticated client capable of reaching the WordPress site. The Exploit Prediction Scoring System reports a probability of 0.439% for this issue.
Root Cause
The root cause is the absence of capability checks on plugin actions before they execute privileged operations. WordPress plugins typically validate user roles using current_user_can() and verify nonces before changes occur. EventPrime through version 3.3.9 omits one or both of these checks on specific handlers, allowing requests without proper authorization to reach state-changing logic. This pattern aligns with [CWE-862] Missing Authorization.
Attack Vector
An attacker sends crafted HTTP requests directly to vulnerable EventPrime endpoints on the target WordPress installation. No authentication, user interaction, or prior foothold is required. Because the vulnerability impacts integrity, attackers focus on tampering with event data or other plugin-managed resources rather than exfiltrating data or causing denial of service. Refer to the Patchstack Vulnerability Analysis for endpoint-level technical detail.
Detection Methods for CVE-2024-24832
Indicators of Compromise
- Unexpected creation, modification, or deletion of EventPrime events, bookings, or attendee records by anonymous or unauthenticated sessions
- HTTP requests to EventPrime AJAX handlers or REST routes lacking authentication cookies or valid nonces
- WordPress audit log entries showing plugin state changes with no associated user account
Detection Strategies
- Inventory all WordPress installations and confirm whether the EventPrime plugin is present at version 3.3.9 or earlier
- Inspect web server access logs for repeated unauthenticated POST requests targeting admin-ajax.php actions or REST endpoints associated with EventPrime
- Enable a WordPress activity monitoring plugin to record plugin-level data changes and correlate them with authenticated sessions
Monitoring Recommendations
- Alert on anomalous spikes of POST traffic to /wp-admin/admin-ajax.php referencing EventPrime action names
- Track database changes to EventPrime tables and flag modifications occurring outside administrator sessions
- Forward WordPress and web server logs to a centralized analytics platform to identify cross-site exploitation attempts
How to Mitigate CVE-2024-24832
Immediate Actions Required
- Upgrade EventPrime to a version released after 3.3.9 that contains the Metagauss authorization fix
- Audit existing EventPrime data for unauthorized modifications introduced before the patch was applied
- Restrict access to the WordPress administrative interface and EventPrime endpoints using IP allowlists where feasible
Patch Information
Metagauss addressed the issue in releases after EventPrime 3.3.9. Site administrators should review the Patchstack Vulnerability Analysis for the fixed version reference and apply the upgrade through the WordPress plugin manager or WP-CLI.
Workarounds
- Deactivate the EventPrime plugin until the patched version can be installed if business operations allow
- Deploy a web application firewall rule to block unauthenticated requests to known vulnerable EventPrime action handlers
- Limit network exposure of the WordPress administrative path through reverse proxy authentication or VPN-only access
# Configuration example
wp plugin update eventprime-event-calendar-management
wp plugin list --name=eventprime-event-calendar-management --fields=name,status,version
