CVE-2025-32594: Simple WP Events Information Disclosure

CVE-2025-32594 Overview

CVE-2025-32594 is a sensitive information disclosure vulnerability in the WPMinds Simple WP Events plugin for WordPress. The flaw affects all versions up to and including 1.8.17. An unauthenticated remote attacker can retrieve embedded sensitive data from the application without user interaction. The vulnerability is classified under [CWE-201: Insertion of Sensitive Information Into Sent Data]. Network-based exploitation requires no privileges, making affected WordPress sites broadly accessible to attackers scanning for vulnerable plugins.

Critical Impact
Unauthenticated attackers can retrieve sensitive data embedded in responses from WordPress sites running Simple WP Events <= 1.8.17, leading to confidentiality loss.

Affected Products

WPMinds Simple WP Events WordPress plugin versions n/a through 1.8.17
WordPress installations using the simple-wp-events plugin
Sites that have not updated past version 1.8.17

Technical Details for CVE-2025-32594

Vulnerability Analysis

The Simple WP Events plugin embeds sensitive information into data sent to clients without proper access controls. [CWE-201] describes vulnerabilities where applications include confidential information in outbound responses that should not be exposed to the requesting party. In this case, the plugin returns data accessible to unauthenticated network requests, exposing information intended to remain internal.

The attack requires no authentication, no user interaction, and low attack complexity. An attacker only needs network access to a WordPress site running the vulnerable plugin. The impact is limited to confidentiality, with integrity and availability remaining unaffected. Exploitation can be automated against any reachable WordPress instance with the plugin installed.

The EPSS probability stands at 0.307%, reflecting current exploitation likelihood based on observed signals.

Root Cause

The root cause is improper handling of data inclusion in plugin responses. The Simple WP Events plugin embeds information into responses without validating whether the requester is authorized to view that data. The plugin treats sensitive fields the same as public event data, returning them to any caller.

Attack Vector

The attack vector is network-based. An attacker sends crafted HTTP requests to endpoints exposed by the simple-wp-events plugin and parses returned responses for embedded sensitive fields. No credentials, session tokens, or user interaction are required. Refer to the Patchstack WordPress Vulnerability Report for endpoint-specific technical details.

Detection Methods for CVE-2025-32594

Indicators of Compromise

Unusual volumes of unauthenticated HTTP GET requests to simple-wp-events plugin endpoints under /wp-content/plugins/simple-wp-events/ or related REST routes
Repeated requests from a single source enumerating event-related URLs across the site
Outbound responses containing fields not normally exposed to anonymous visitors

Detection Strategies

Inventory WordPress installations and identify any using simple-wp-events version 1.8.17 or earlier
Review web server access logs for anonymous requests targeting plugin endpoints and unusual response sizes
Deploy web application firewall rules that flag enumeration patterns against WordPress plugin paths

Monitoring Recommendations

Forward WordPress access logs and PHP error logs to a centralized logging platform for analysis
Alert on spikes in unauthenticated requests to plugin-specific paths
Monitor for known scanner user-agents probing WordPress plugin vulnerabilities

How to Mitigate CVE-2025-32594

Immediate Actions Required

Update the Simple WP Events plugin to a version released after 1.8.17 once available from WPMinds
If no fixed version is available, deactivate and remove the simple-wp-events plugin from affected WordPress installations
Audit existing event data and configurations for sensitive content that may have already been exposed

Patch Information

Review the Patchstack WordPress Vulnerability Report for the current patch status. At the time of the NVD record, the vulnerability affects versions through 1.8.17 with no fixed release listed in the available data.

Workarounds

Restrict access to vulnerable plugin endpoints using web application firewall rules or .htaccess directives until a patch is applied
Remove or sanitize sensitive data stored within Simple WP Events records to reduce exposure if the plugin cannot be immediately removed
Place affected WordPress sites behind authentication or IP allowlists where feasible

bash

# Example: block access to the vulnerable plugin path via .htaccess
<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteRule ^wp-content/plugins/simple-wp-events/.*$ - [F,L]
</IfModule>
