CVE-2025-63079: Broken Access Control in Live Copy Paste for Elementor ≤1.5.3

Technical summary

CVE-2025-63079 is a broken access control vulnerability (CWE-862) in Live Copy Paste for Elementor up to version 1.5.3. The flaw allows authenticated contributors to access or view resources that should be restricted to higher-privilege roles. The attack vector is network-based, requires valid contributor credentials, and does not depend on user interaction. The vulnerability results in confidentiality impact (information disclosure) without affecting integrity or availability.

Business impact

For WordPress administrators managing multi-user editorial environments, this vulnerability undermines role-based access control (RBAC) boundaries. Contributors may gain visibility into design templates, page structures, or other Elementor assets intended for editors or administrators only. While not directly exploitable for data theft or site compromise, it creates information leakage that could inform subsequent attacks or expose competitive design assets. Organizations relying on contributor role restrictions for content separation should treat this as a trust boundary violation.

Affected systems

The Live Copy Paste plugin for Elementor in versions 1.5.3 and earlier is affected. WordPress sites with this plugin installed and active contributor users pose the exposure. The scope is limited to sites actively using this specific plugin; unaffected sites do not have this extension installed. No versions of WordPress core, Elementor core, or other major plugins are inherently affected.

Exploitability

Exploitability is moderate. An attacker must already possess valid contributor credentials on a target WordPress site where the Live Copy Paste plugin is installed. No public exploit code is known to be actively weaponized. The vulnerability requires authentication, eliminating opportunistic exploitation, but a disgruntled contributor or account compromise could enable misuse. The attack surface is limited to sites with this niche plugin installed.

Remediation

Update the Live Copy Paste plugin to the first version published after 1.5.3. Verify the patch version against the official plugin repository or vendor advisory. Until patched, site administrators may consider disabling the plugin if contributor-level access is not essential, or restrict Elementor editing capabilities to administrator and editor roles only via WordPress role management.

Patch guidance

Verify the availability of a patched version of Live Copy Paste for Elementor through the WordPress plugin repository or the plugin vendor's official advisory. Apply the update once a fixed version is confirmed. Test the patch in a staging environment first to ensure compatibility with your Elementor setup and active page templates. If the vendor has not yet released a patch, monitor their security advisory and release notes closely.

Detection guidance

Review WordPress user audit logs for contributor accounts accessing or interacting with Elementor design assets or copy-paste functionality beyond their typical scope. Check the plugin directory in wp-content/plugins/ to confirm the installed version of Live Copy Paste. Implement security scanning tools that check for outdated or vulnerable plugins. Monitor for suspicious API calls or REST endpoint access from contributor-level roles. If possible, isolate network traffic from contributor accounts to detect unusual data exfiltration patterns.

Why prioritize this

While the CVSS score of 4.3 (MEDIUM) reflects limited immediate operational impact, this vulnerability warrants timely patching because it directly violates the access control model most WordPress sites rely on. The issue is more concerning in multi-tenant or agency environments where content isolation is a contractual requirement. Patch urgency should be escalated if your site grants contributor access to external or untrusted users, or if you store sensitive design IP in Elementor templates. For sites with only internal, trusted contributors, priority can be standard.

Risk score, explained

The CVSS 3.1 score of 4.3 reflects a network-exploitable vulnerability requiring valid credentials (PR:L) with no user interaction needed, resulting in low confidentiality impact and no integrity or availability damage (C:L/I:N/A:N). The score appropriately captures that an attacker cannot escalate privileges, crash the system, or modify data, but can view unauthorized information. The 'MEDIUM' severity label underscores that this is a real security control bypass, not a cosmetic or negligible issue, and should not be indefinitely deferred.
