CVE-2026-103082: LA-Studio Element Kit SSRF Vulnerability

CVE-2026-103082 Overview

CVE-2026-103082 is a Server-Side Request Forgery (SSRF) vulnerability in the LA-Studio Element Kit for Elementor WordPress plugin. The flaw affects all versions up to and including 1.6.2. An unauthenticated attacker can coerce the WordPress server to issue arbitrary HTTP requests to internal or external destinations. The vulnerability is tracked under CWE-918 and allows attackers to probe internal network services, access cloud metadata endpoints, or interact with other systems reachable from the vulnerable host.

Critical Impact
Unauthenticated attackers can abuse the plugin to send attacker-controlled HTTP requests from the WordPress server, enabling internal network reconnaissance and limited data exposure.

Affected Products

Technical Details for CVE-2026-103082

Vulnerability Analysis

The LA-Studio Element Kit for Elementor plugin exposes functionality that fetches remote resources based on user-supplied input without sufficient validation of the target URL. An attacker can submit a request containing a crafted URL that references internal IP ranges, loopback addresses, or cloud provider metadata services. The WordPress server then performs the outbound request on behalf of the attacker and may return response data in the HTTP response. Server-Side Request Forgery (SSRF) in a WordPress context frequently enables reconnaissance of hosts behind the perimeter, enumeration of internal services, and interaction with unauthenticated management interfaces. The attack requires no authentication and no user interaction.

Root Cause

The root cause is missing validation and allow-listing of URLs passed to the plugin's HTTP request handling logic. The plugin accepts arbitrary schemes and hostnames, including private address space such as 127.0.0.1, 169.254.169.254, and RFC1918 ranges. This matches the pattern described by CWE-918: Server-Side Request Forgery.

Attack Vector

An attacker sends an HTTP request to a vulnerable plugin endpoint, specifying a crafted target URL as a parameter. The WordPress backend processes the request using PHP HTTP client functions and returns relevant response content or metadata. Attackers typically target cloud metadata services to retrieve temporary credentials, internal admin panels, and services bound to localhost. See the Patchstack SSRF Vulnerability Advisory for additional detail.

Detection Methods for CVE-2026-103082

Indicators of Compromise

Outbound HTTP requests from the WordPress host to internal IP ranges such as 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, or 127.0.0.1.
Requests from the WordPress server to cloud metadata endpoints such as 169.254.169.254.
Unexpected wp-admin/admin-ajax.php or plugin-specific endpoint requests containing URL parameters pointing to internal hosts.

Detection Strategies

Inspect web server access logs for requests referencing lastudio-element-kit endpoints with embedded URLs in query or body parameters.
Correlate inbound HTTP requests to the WordPress server with subsequent outbound HTTP connections initiated by the PHP worker process.
Alert on PHP processes performing DNS lookups or TCP connections to private address space or cloud metadata IPs.

Monitoring Recommendations

Enable egress logging on hosts running WordPress and forward logs to a central SIEM for correlation.
Monitor the lastudio-element-kit plugin directory for configuration changes and version drift.
Track plugin version inventory across WordPress fleets to identify hosts running 1.6.2 or earlier.

How to Mitigate CVE-2026-103082

Immediate Actions Required

Identify every WordPress instance running LA-Studio Element Kit for Elementor and record the installed version.
Update the plugin to a release later than 1.6.2 once the vendor publishes a patched version.
Restrict outbound traffic from WordPress hosts so that connections to internal network ranges and cloud metadata IPs are blocked.
Rotate any credentials that may have been reachable through the cloud instance metadata service.

Patch Information

At the time of publication, the advisory lists versions up to and including 1.6.2 as vulnerable. Monitor the Patchstack SSRF Vulnerability Advisory and the LA-Studio plugin page on WordPress.org for a patched release.

Workarounds

Deactivate and remove the LA-Studio Element Kit for Elementor plugin until a patched version is available.
Deploy a Web Application Firewall (WAF) rule that blocks requests to plugin endpoints containing URLs pointing to private or link-local addresses.
Enforce Instance Metadata Service v2 (IMDSv2) with hop-limit 1 on AWS instances to reduce metadata exposure through SSRF.
Apply egress filtering at the host or network layer so PHP processes cannot reach internal management interfaces.
