CVE-2025-32299 Overview
CVE-2025-32299 is a sensitive information disclosure vulnerability in the Themovation QuickCal - Appointment Booking Calendar plugin for WordPress. The flaw affects all versions up to and including 1.0.15. An authenticated attacker with low privileges can retrieve embedded sensitive data that should not be accessible through their role. The issue is categorized under [CWE-497]: Exposure of Sensitive System Information to an Unauthorized Control Sphere.
Critical Impact
A low-privileged authenticated user can read embedded sensitive data from the QuickCal plugin over the network without user interaction, exposing appointment data or configuration details to unauthorized WordPress accounts.
Affected Products
- Themovation QuickCal - Appointment Booking Calendar for WordPress
- All versions from n/a through 1.0.15
- WordPress installations running the vulnerable quickcal plugin

Technical Details for CVE-2025-32299
Vulnerability Analysis
The QuickCal plugin exposes sensitive system or application information to actors operating outside the intended control sphere. In practice, this means an authenticated WordPress user with limited privileges can access data that should be restricted to administrators or plugin owners. The vulnerability requires network access to the WordPress site and low-privilege authentication, but no user interaction. Exploitation impacts confidentiality only; integrity and availability of the site remain unaffected. The Patchstack advisory tracks this issue against QuickCal versions up to 1.0.15.
Root Cause
The root cause is improper access control over data that the plugin embeds or returns through its interfaces. Under [CWE-497], the application does not sufficiently restrict which authenticated roles can retrieve internal data. The plugin likely lacks a capability check (current_user_can()) or nonce verification on endpoints or output paths that surface booking, configuration, or system information.
Attack Vector
An attacker first obtains a low-privileged WordPress account, such as Subscriber or Contributor, on a site running the vulnerable QuickCal plugin. The attacker then issues an authenticated request to a plugin endpoint or page that returns embedded sensitive data. Because the plugin does not enforce adequate authorization, the server returns the data to the low-privileged caller. The attack requires only network reachability to the WordPress instance and does not depend on social engineering.

Detection Methods for CVE-2025-32299
Indicators of Compromise
- Authenticated HTTP requests from low-privileged WordPress accounts to QuickCal plugin endpoints under /wp-admin/admin-ajax.php or /wp-json/ returning larger-than-expected response bodies.
- Repeated access to QuickCal-related URLs by non-administrator sessions.
- Unexpected exports or downloads of appointment or configuration data by Subscriber or Contributor roles.
Detection Strategies
- Review WordPress access logs for authenticated requests to QuickCal endpoints originating from accounts that do not manage bookings.
- Enable WordPress audit logging plugins to track REST API and AJAX calls tied to the quickcal plugin.
- Compare installed plugin versions against the vulnerable range (<= 1.0.15) during routine asset inventory.
Monitoring Recommendations
- Alert on newly created low-privilege WordPress accounts that immediately access plugin data endpoints.
- Monitor outbound traffic from the web server for large data transfers correlated with QuickCal requests.
- Track plugin file changes and version drift across WordPress fleets.
How to Mitigate CVE-2025-32299
Immediate Actions Required
- Inventory all WordPress sites and identify installations running QuickCal - Appointment Booking Calendar at version 1.0.15 or earlier.
- Update the QuickCal plugin to a version above 1.0.15 once a fixed release is published by Themovation.
- Restrict user registration and audit existing low-privileged accounts on sites where the plugin is active.
Patch Information
The enriched data does not identify a specific fixed version. Refer to the Patchstack Vulnerability Report for the current patch status and recommended upgrade path from the vendor.
Workarounds
- Deactivate and remove the QuickCal plugin from affected WordPress sites until a patched version is available.
- Disable open user registration in WordPress settings to reduce the pool of low-privileged accounts that can exploit the flaw.
- Deploy a Web Application Firewall rule to block or log requests to QuickCal endpoints from non-administrator roles.
- Enforce least privilege by auditing role assignments and removing unnecessary Subscriber or Contributor accounts.
# Configuration example: disable open registration and remove the plugin via WP-CLI
wp option update users_can_register 0
wp plugin deactivate quickcal
wp plugin uninstall quickcal
