CVE-2026-93527 Overview
CVE-2026-93527 is a SQL injection vulnerability [CWE-89] affecting the Live Copy Paste for Elementor WordPress plugin in versions up to and including 1.5.10. The flaw allows an authenticated user with Contributor-level privileges to inject arbitrary SQL statements into database queries executed by the plugin. Successful exploitation exposes sensitive database contents and can affect the availability of the underlying WordPress installation. The vulnerability is network-exploitable and requires low attack complexity, making it a practical target on sites that permit Contributor registrations.
Critical Impact
Authenticated Contributors can read arbitrary database records, including WordPress user records and session data, by injecting SQL through vulnerable plugin parameters.
Affected Products
- Live Copy Paste for Elementor plugin for WordPress
- All versions up to and including 1.5.10
- WordPress sites that permit Contributor-role registrations

Technical Details for CVE-2026-93527
Vulnerability Analysis
The vulnerability is a classic SQL injection flaw [CWE-89] in the Live Copy Paste for Elementor plugin. The plugin exposes functionality accessible to authenticated Contributor users that passes user-controlled input into a SQL query without proper parameterization or sanitization. An attacker holding a Contributor account can craft input that alters the intended query structure, leading to unauthorized data retrieval and limited impact on database availability.
The scope is marked as changed, meaning exploitation impacts resources beyond the vulnerable component. In WordPress deployments, this maps to the shared database used by the core CMS and other installed plugins. Confidentiality impact is high because injected queries can extract user records, password hashes, session tokens, and configuration secrets from the wp_users and wp_options tables.
See the Patchstack SQL Injection Vulnerability advisory for additional technical context.
Root Cause
The root cause is improper neutralization of special elements used in a SQL command. The plugin concatenates user-supplied values directly into query strings rather than using prepared statements through the WordPress $wpdb->prepare() API. This allows attacker-controlled tokens such as quotes, UNION SELECT clauses, and comment sequences to escape the intended query context.
Attack Vector
Exploitation requires an authenticated session at the Contributor privilege level. The attacker submits a malicious payload through a plugin endpoint reachable over the network, typically via admin-ajax.php or a REST API route registered by the plugin. No user interaction is required beyond the attacker's own session. The vulnerability does not require Administrator or Editor rights, which lowers the barrier on sites that accept Contributor registrations or where a Contributor account has been compromised.
A verified proof-of-concept is not publicly listed for this CVE. Refer to the Patchstack advisory for disclosure details.
Detection Methods for CVE-2026-93527
Indicators of Compromise
- Unusual POST requests from Contributor-role sessions to plugin AJAX or REST endpoints containing SQL keywords such as UNION, SELECT, SLEEP, or INFORMATION_SCHEMA.
- Database error entries in debug.log referencing plugin-originated queries with malformed syntax.
- Unexpected outbound queries against sensitive tables such as wp_users, wp_usermeta, or wp_options.
- New or recently activated Contributor accounts that immediately interact with Live Copy Paste for Elementor endpoints.
Detection Strategies
- Enable WordPress query logging or a database activity monitor to capture full statements executed by the plugin's process context.
- Deploy a web application firewall rule set that flags SQL metacharacters in requests targeting plugin routes.
- Correlate authentication events with plugin endpoint access to identify low-privilege accounts issuing high-volume requests.
Monitoring Recommendations
- Monitor HTTP request logs for repeated 500-status responses tied to plugin endpoints, which often indicate injection probing.
- Track creation of Contributor accounts and alert on rapid role assignment followed by plugin interaction.
- Watch for time-based injection patterns by measuring anomalously long response times on plugin endpoints.
How to Mitigate CVE-2026-93527
Immediate Actions Required
- Update Live Copy Paste for Elementor to a version later than 1.5.10 once the vendor publishes a fixed release.
- Audit all Contributor and higher-privilege accounts and disable any that are inactive or unrecognized.
- Temporarily disable the Live Copy Paste for Elementor plugin on sites that permit open user registration until a patch is applied.
- Rotate WordPress secret keys in wp-config.php and force password resets if exploitation is suspected.
Patch Information
A fixed version addressing CVE-2026-93527 is tracked in the Patchstack advisory. Administrators should confirm the installed version is later than 1.5.10 and validate the update through the WordPress plugins dashboard.
Workarounds
- Restrict user registration to trusted identity providers and disable open Contributor sign-up in WordPress general settings.
- Deploy a WAF rule that blocks SQL syntax in parameters submitted to the plugin's AJAX and REST endpoints.
- Apply least-privilege database credentials so the WordPress database user cannot access tables outside the site schema.
# Configuration example: disable open registration and enforce role review
wp option update users_can_register 0
wp option update default_role subscriber
wp user list --role=contributor --fields=ID,user_login,user_registered
