CVE-2025-68045: WP Event Solution Auth Bypass Flaw

CVE-2025-68045 Overview

CVE-2025-68045 is a broken access control vulnerability affecting the WP Event Solution WordPress plugin in versions up to and including 4.1.12. The flaw allows unauthenticated attackers to access functionality that should be restricted to authorized users. The vulnerability is tracked under CWE-862: Missing Authorization and is exploitable remotely over the network without user interaction.

The issue affects WordPress sites running the plugin and can lead to unauthorized disclosure of information managed by the plugin. The vulnerability was disclosed through Patchstack's vulnerability database.

Critical Impact
Unauthenticated attackers can bypass access controls in WP Event Solution <= 4.1.12 to reach functionality that should require authentication, resulting in confidentiality impact on affected WordPress installations.

Affected Products

WP Event Solution WordPress plugin versions <= 4.1.12
WordPress installations with the vulnerable plugin enabled
Sites exposing plugin endpoints to unauthenticated network traffic

Technical Details for CVE-2025-68045

Vulnerability Analysis

The vulnerability stems from missing authorization checks in the WP Event Solution plugin. The plugin exposes functionality that fails to verify the caller's identity or permission level before processing requests. Attackers can reach these endpoints directly over HTTP without authenticating to the WordPress instance.

Broken access control flaws of this class typically occur when plugin developers register REST API routes, AJAX actions, or admin-post handlers without an accompanying permission_callback or current_user_can() check. The result is that operations intended for site administrators or authenticated event organizers become reachable to anonymous network clients.

The CVSS vector indicates confidentiality impact only, suggesting the flaw exposes data that should be access-restricted rather than allowing modification or service disruption. The EPSS probability sits at 0.232%, placing it in the lower portion of currently scored vulnerabilities, though exposure increases as PoC details circulate.

Root Cause

The root cause is a missing authorization check on one or more plugin endpoints. The plugin registers handlers that perform sensitive read operations without validating whether the requestor holds the required capability or session. This maps to CWE-862: Missing Authorization.

Attack Vector

An attacker sends crafted HTTP requests to the vulnerable plugin endpoints on the target WordPress site. No credentials, tokens, or social engineering are required. Because the attack runs over the network with low complexity, automated scanners can identify and exploit vulnerable hosts at scale. Specific endpoint and parameter details are documented in the Patchstack Security Advisory.

Detection Methods for CVE-2025-68045

Indicators of Compromise

Unauthenticated HTTP requests to WP Event Solution REST routes or admin-ajax.php actions originating from unfamiliar IP addresses
Spikes in access to plugin-specific URLs under /wp-json/ namespaces associated with the plugin
Sequential enumeration patterns against event, attendee, or organizer endpoints provided by the plugin

Detection Strategies

Audit installed plugins and confirm whether WP Event Solution is present at version <= 4.1.12
Review web server access logs for requests to plugin endpoints from clients that never authenticate to /wp-login.php
Deploy a Web Application Firewall (WAF) rule set that flags unauthenticated access to plugin REST routes

Monitoring Recommendations

Forward WordPress access and audit logs to a centralized SIEM for correlation and retention
Alert on bursts of 200 OK responses to plugin endpoints from a single source IP without a preceding authenticated session
Track changes in plugin file integrity and database tables associated with WP Event Solution

How to Mitigate CVE-2025-68045

Immediate Actions Required

Update WP Event Solution to a version released after 4.1.12 as soon as the vendor publishes a fixed release
Inventory all WordPress instances to identify vulnerable plugin installations
Restrict access to WordPress administrative and REST endpoints using IP allowlists where feasible

Patch Information

Refer to the Patchstack Security Advisory for the current patch status and fixed version information. Apply the vendor-released update through the WordPress plugin management console.

Workarounds

Disable the WP Event Solution plugin until a patched version is installed if no immediate update is available
Apply WAF virtual patching rules that block unauthenticated requests to the vulnerable plugin endpoints
Restrict access to /wp-json/ and admin-ajax.php from untrusted networks at the reverse proxy or CDN layer

bash

# Configuration example - block unauthenticated access at nginx layer
location ~* /wp-json/wp-event-solution/ {
    # Require an authenticated session cookie before reaching the plugin
    if ($http_cookie !~* "wordpress_logged_in") {
        return 403;
    }
}
