CVE-2026-45214: Xpro Elementor Addons SQLi Vulnerability

CVE-2026-45214 Overview

CVE-2026-45214 is a blind SQL injection vulnerability in the Xpro Elementor Addons plugin for WordPress. The flaw affects all versions of xpro-elementor-addons up to and including 1.5.1. Authenticated attackers with low-privilege access can inject malicious SQL payloads through unsanitized input parameters. Because the issue exists at the database query layer, exploitation can disclose sensitive WordPress data such as user credentials, session tokens, and configuration secrets. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command).

Critical Impact

Authenticated attackers can extract sensitive database contents from WordPress sites running Xpro Elementor Addons <= 1.5.1 through blind SQL injection, with scope change extending impact beyond the vulnerable component.

Affected Products

• Xpro Elementor Addons WordPress plugin (xpro-elementor-addons)
• All versions from initial release through 1.5.1
• WordPress sites with the plugin installed and active

Technical Details for CVE-2026-45214

Vulnerability Analysis

The vulnerability stems from improper neutralization of special characters in SQL statements constructed by the Xpro Elementor Addons plugin. User-supplied parameters reach database queries without parameterized binding or adequate sanitization. Attackers submit crafted input that alters the structure of the underlying SQL query.

The attack is classified as blind because the application does not return raw query output to the requester. Attackers infer database contents by observing response differences, time delays, or boolean-based behavior changes. The scope is marked as changed, meaning a successful exploit can affect resources beyond the plugin's own security context, including the wider WordPress database and any data shared across tenants.

The Exploit Prediction Scoring System (EPSS) currently rates this issue with a low probability of near-term exploitation, but blind SQL injection in WordPress plugins is a well-trodden path for opportunistic attackers once tooling is published.

Root Cause

The plugin concatenates request parameters directly into SQL statements rather than using prepared statements through WordPress core functions such as $wpdb->prepare(). Input from authenticated low-privilege users passes through plugin endpoints without strict validation of types, character sets, or expected value ranges, allowing SQL metacharacters to alter query semantics.

Attack Vector

Exploitation requires network access to a WordPress site running the vulnerable plugin and an authenticated session with low privileges, such as a subscriber or contributor account. The attacker sends crafted HTTP requests to a vulnerable plugin endpoint with payloads designed to elicit measurable differences in server responses. Iterative requests reconstruct database contents one bit or character at a time. No user interaction is required from administrators.

No verified public proof-of-concept code is available at this time. Technical details are documented in the Patchstack Vulnerability Report.

Detection Methods for CVE-2026-45214

Indicators of Compromise

• HTTP requests to Xpro Elementor Addons endpoints containing SQL metacharacters such as ', ", --, UNION, SLEEP(, or BENCHMARK(
• Repeated authenticated requests from the same low-privilege user with small parameter mutations
• Unusual response latency patterns consistent with time-based blind SQL injection probing
• Web server logs showing high-volume parameterized requests against plugin AJAX or REST routes

Detection Strategies

• Inspect WordPress access logs for requests targeting plugin paths under wp-content/plugins/xpro-elementor-addons/ or related AJAX actions with suspicious query strings
• Deploy a web application firewall rule set that flags SQL injection signatures against authenticated WordPress endpoints
• Correlate authentication events for low-privilege accounts with bursts of parameterized POST or GET activity
• Monitor database query logs for malformed statements, syntax errors, or unusually long execution times

Monitoring Recommendations

• Enable WordPress debug logging and database slow query logging on affected hosts during the remediation window
• Track creation of new subscriber or contributor accounts followed by immediate plugin endpoint access
• Alert on outbound data transfers from the database server that exceed historical baselines

How to Mitigate CVE-2026-45214

Immediate Actions Required

• Identify all WordPress instances running Xpro Elementor Addons version 1.5.1 or earlier
• Deactivate and remove the plugin until a patched version is installed if business needs allow
• Restrict registration and audit existing low-privilege accounts for unexpected activity
• Rotate WordPress administrator credentials and database secrets if exploitation is suspected

Patch Information

At the time of publication, the vendor advisory referenced in the Patchstack Vulnerability Report lists versions through 1.5.1 as affected. Administrators should upgrade to the latest release available from the WordPress plugin repository and verify the installed version is greater than 1.5.1.

Workarounds

• Place the WordPress site behind a web application firewall with SQL injection signatures enabled and tuned for plugin AJAX routes
• Disable open user registration and restrict access to authenticated plugin endpoints by IP allowlist where feasible
• Apply virtual patching rules at the reverse proxy to block requests containing SQL metacharacters against the affected plugin paths

# Example wp-cli commands to inventory and disable the plugin
wp plugin list --name=xpro-elementor-addons --fields=name,status,version
wp plugin deactivate xpro-elementor-addons
wp plugin update xpro-elementor-addons
