CVE-2025-63079: Elementor Live Copy Paste Auth Bypass

CVE-2025-63079 Overview

CVE-2025-63079 is a broken access control vulnerability in the Live Copy Paste for Elementor WordPress plugin. Versions 1.5.3 and earlier are affected. The flaw stems from a missing authorization check [CWE-862], allowing authenticated users with Contributor-level privileges to access functionality that should be restricted to higher-privileged roles.

The issue requires low-privilege authentication and no user interaction. Exploitation is limited to confidentiality impact, with no direct integrity or availability effect.

Critical Impact
Authenticated Contributors can bypass access controls in the Live Copy Paste for Elementor plugin, exposing plugin functionality that should require elevated permissions.

Affected Products

Live Copy Paste for Elementor WordPress plugin, versions <= 1.5.3
WordPress sites running the vulnerable plugin with Contributor accounts enabled
Multi-author WordPress environments where untrusted users hold Contributor roles

Technical Details for CVE-2025-63079

Vulnerability Analysis

The vulnerability is a broken access control issue classified under [CWE-862] Missing Authorization. The Live Copy Paste for Elementor plugin exposes one or more actions without verifying the requesting user has sufficient privileges. Any authenticated user with Contributor-level access can invoke these actions.

Contributors in WordPress can write posts but cannot publish or manage other users' content. When plugins fail to check capabilities on their AJAX handlers or REST endpoints, Contributors gain unintended access. The confidentiality impact reflects that the exposed functionality leaks information rather than allowing modification.

The EPSS score is 0.197%, indicating a low predicted probability of exploitation in the near term.

Root Cause

The root cause is missing or insufficient authorization checks on plugin endpoints. The plugin likely relies on nonce validation or authentication alone without calling current_user_can() with an appropriate capability such as edit_others_posts or manage_options. This design gap lets any logged-in user with a valid nonce reach protected functionality.

Attack Vector

An attacker requires a valid Contributor account on the target WordPress site. The attacker authenticates, obtains any required nonce from a permitted page, and sends a crafted HTTP request to the vulnerable plugin endpoint. The server executes the request without verifying the caller's role, returning data that should be restricted.

Exploitation does not require user interaction from an administrator. The attack is fully remote over the network. See the Patchstack Security Advisory for technical details.

Detection Methods for CVE-2025-63079

Indicators of Compromise

Unexpected admin-ajax.php or REST API requests originating from Contributor-level accounts targeting Live Copy Paste plugin actions
Access log entries showing repeated POST requests to plugin endpoints from low-privilege users
Sudden increase in plugin-specific action calls not tied to normal editorial workflows

Detection Strategies

Audit WordPress access logs for requests to Live Copy Paste for Elementor endpoints from non-administrator sessions
Correlate authenticated user sessions with plugin action invocations to identify privilege mismatches
Deploy a web application firewall rule that flags Contributor-role requests to sensitive plugin actions

Monitoring Recommendations

Enable WordPress audit logging for user role activity and plugin action invocations
Monitor creation of new Contributor accounts and their subsequent request patterns
Track outbound data volumes from wp-admin endpoints to detect data enumeration attempts

How to Mitigate CVE-2025-63079

Immediate Actions Required

Update Live Copy Paste for Elementor to a version above 1.5.3 once released by the vendor
Review all Contributor and low-privilege accounts and remove unused or untrusted users
Restrict plugin installation on sites with open registration or many Contributor accounts

Patch Information

At the time of publication, refer to the Patchstack advisory for the latest fixed version and vendor patch status. Apply the update through the WordPress plugin dashboard or via wp-cli.

Workarounds

Deactivate the Live Copy Paste for Elementor plugin until a patched version is available
Restrict access to admin-ajax.php and plugin REST routes at the WAF layer for non-editor roles
Temporarily downgrade Contributor accounts or convert them to Subscriber role where practical

bash

# Disable the vulnerable plugin via wp-cli until patched
wp plugin deactivate live-copy-paste

# List Contributor accounts for review
wp user list --role=contributor --fields=ID,user_login,user_registered
