CVE-2025-62052 Overview
CVE-2025-62052 is a missing authorization vulnerability [CWE-862] in the Horea Radu One Page Express Companion plugin for WordPress. The flaw affects all versions of one-page-express-companion up to and including 1.6.43. An authenticated attacker with low privileges can invoke plugin functionality that lacks proper capability checks, leading to unauthorized actions against the site. The issue is classified as broken access control by Patchstack.
Critical Impact
Authenticated users with minimal privileges can bypass authorization controls in the One Page Express Companion plugin, resulting in limited integrity impact on affected WordPress sites.
Affected Products

Technical Details for CVE-2025-62052
Vulnerability Analysis
The vulnerability stems from missing authorization checks within the One Page Express Companion plugin. The plugin exposes one or more actions accessible to authenticated users without verifying that the caller holds the required WordPress capability. This class of flaw, tracked as [CWE-862] Missing Authorization, allows a subscriber-level account to reach functionality that should be reserved for administrators or editors.
The attack requires network access to the WordPress site and low-privilege authentication, but no user interaction. Because the impact is limited to integrity with no confidentiality or availability effect, the practical consequences depend on which plugin functions can be reached. Refer to the Patchstack Vulnerability Report for the specific endpoints affected.
Root Cause
The root cause is the absence of capability checks such as current_user_can() or nonce verification via check_admin_referer() on privileged plugin handlers. WordPress plugins commonly register callbacks via admin_post_*, wp_ajax_*, or REST API routes. When these handlers omit permission callbacks, any authenticated session can invoke them.
Attack Vector
An attacker first obtains a low-privilege account, for example by registering on a site that allows open subscription. The attacker then issues an HTTP request to the vulnerable plugin endpoint, supplying parameters that trigger the unauthorized action. Because no capability check gates the operation, the request succeeds and modifies plugin or site state within the limits of the exposed functionality.
No public proof-of-concept exploit code is currently available. The vulnerability manifests in plugin handlers that lack authorization enforcement. See the Patchstack advisory linked above for further technical details.

Stop Identity AttacksDetection Methods for CVE-2025-62052
Indicators of Compromise
- Unexpected changes to WordPress options, pages, or plugin settings tied to one-page-express-companion
- HTTP POST requests to admin-ajax.php or admin-post.php from low-privilege authenticated sessions targeting plugin actions
- New or modified content created by subscriber or contributor accounts that would normally lack such permissions
Detection Strategies
- Audit WordPress access logs for requests referencing one-page-express-companion handlers originating from non-administrator sessions
- Review the plugin version currently deployed and flag any installation at or below 1.6.43
- Correlate authentication events with subsequent privileged plugin actions to identify authorization bypass patterns
Monitoring Recommendations
- Enable WordPress activity logging to capture user actions, role changes, and content modifications
- Alert on HTTP 200 responses from plugin AJAX endpoints when the requesting user holds only subscriber or contributor roles
- Monitor file integrity for the plugin directory and for site configuration files touched by plugin logic
How to Mitigate CVE-2025-62052
Immediate Actions Required
- Identify all WordPress instances running the One Page Express Companion plugin at version 1.6.43 or earlier
- Update the plugin to a version that resolves the missing authorization flaw once released by the vendor
- Restrict user registration and audit existing low-privilege accounts for signs of abuse
Patch Information
At the time of publication, no fixed version is listed in the enriched data. Track the Patchstack Vulnerability Report for a vendor-supplied patch and apply it as soon as it becomes available.
Workarounds
- Deactivate and remove the one-page-express-companion plugin until a patched version is published
- Enforce least-privilege on user accounts and disable open registration where operationally feasible
- Deploy a WordPress web application firewall rule that blocks unauthenticated or low-privilege requests to the vulnerable plugin endpoints
# Disable the vulnerable plugin via WP-CLI until a fix is available
wp plugin deactivate one-page-express-companion
wp plugin list --name=one-page-express-companion --fields=name,status,version
