CVE-2025-53288 Overview
CVE-2025-53288 is a missing authorization vulnerability in the Adrian Ladó PlatiOnline Payments WordPress plugin. The flaw affects all versions up to and including 7.0.0. It stems from incorrectly configured access control security levels within the plugin, mapped to [CWE-862].
An authenticated attacker with low privileges can access functionality that should require higher authorization. The exploit requires network access and no user interaction, but confers only limited integrity impact and no confidentiality or availability impact.
Critical Impact
Authenticated low-privilege users can bypass access control checks in the PlatiOnline Payments plugin to reach protected plugin functionality, potentially altering payment-related plugin state.
Affected Products
- PlatiOnline Payments WordPress plugin (plationline) versions up through 7.0.0
- WordPress sites integrating PlatiOnline Payments for checkout processing
- Any WordPress deployment with authenticated user registration exposed to untrusted users

Technical Details for CVE-2025-53288
Vulnerability Analysis
The PlatiOnline Payments plugin exposes plugin actions without verifying whether the requesting user holds the required capability. WordPress plugins commonly gate privileged actions with current_user_can() checks or nonce verification against a capability. The plugin fails to enforce these controls consistently across its entry points.
The issue is classified as broken access control. Any authenticated session, including WordPress accounts at the Subscriber level, satisfies the privilege prerequisite. Impact is limited to integrity, meaning the attacker can modify plugin data but cannot directly extract confidential information or crash the site.
Root Cause
The root cause is a missing authorization check ([CWE-862]) on one or more plugin request handlers. The plugin registers actions or endpoints that execute privileged logic without validating the caller against a capability such as manage_options or a purchase-scoped permission. Access control security levels defined in the plugin design are not consistently applied at runtime.
Attack Vector
Exploitation is network-based over standard HTTP or HTTPS to the WordPress site. The attacker authenticates using any valid low-privilege account, then submits a crafted request to a plugin action, AJAX endpoint, or admin-post handler that lacks the appropriate capability check. The server processes the request as if the caller were authorized.
See the Patchstack Vulnerability Report for technical details specific to the affected handlers.
Detection Methods for CVE-2025-53288
Indicators of Compromise
- Requests from low-privilege authenticated sessions to PlatiOnline admin-post or AJAX endpoints such as admin-ajax.php?action=plationline_* or admin-post.php?action=plationline_*.
- Unexpected modifications to plugin options, transactions, or configuration records tied to non-administrator user IDs.
- Access log entries showing Subscriber-level accounts POSTing to /wp-admin/ handlers registered by the plugin.
Detection Strategies
- Audit WordPress access logs for requests to PlatiOnline plugin endpoints where the authenticated user role is below Administrator or Shop Manager.
- Compare plugin option and postmeta write events with the acting user's capability set to identify authorization mismatches.
- Deploy a Web Application Firewall (WAF) rule set that inspects action parameter values against a role allow-list.
Monitoring Recommendations
- Enable WordPress audit logging for privileged actions and correlate with authentication events in a centralized log platform.
- Alert on any change to plugin settings, API keys, or payment endpoints performed by non-administrative accounts.
- Track anomalies in new user registrations followed shortly by requests to plugin admin handlers.
How to Mitigate CVE-2025-53288
Immediate Actions Required
- Update the PlatiOnline Payments plugin to a version later than 7.0.0 once the vendor publishes a fixed release.
- Disable the plugin on any WordPress site that does not actively process PlatiOnline transactions.
- Restrict new user registration or set the default role to a minimal capability while a patch is unavailable.
- Rotate any API credentials or merchant keys stored by the plugin if unauthorized modifications are suspected.
Patch Information
Refer to the Patchstack Vulnerability Report for the current patch status. As of the last NVD update, the advisory tracks versions up through 7.0.0 as affected. Administrators should monitor the WordPress plugin repository for a corrected release and apply it promptly.
Workarounds
- Deploy WAF rules that block requests to PlatiOnline plugin endpoints from sessions lacking Administrator or Shop Manager roles.
- Temporarily disable self-service registration on the WordPress site to reduce the pool of authenticated attackers.
- Enforce two-factor authentication on all privileged accounts to limit lateral movement if a low-privilege account is compromised.
- Isolate the WordPress admin interface behind IP allow-listing where operationally feasible.
