CVE-2026-24613 Overview
CVE-2026-24613 is a Missing Authorization vulnerability [CWE-862] in the Ecwid by Lightspeed Ecommerce Shopping Cart plugin for WordPress. The flaw affects all versions of the ecwid-shopping-cart plugin up to and including version 7.0.6. The vulnerability stems from incorrectly configured access control security levels, allowing unauthenticated network attackers to interact with plugin functionality that should require authorization. Successful exploitation can degrade availability of affected WordPress installations running the plugin.
Critical Impact
Unauthenticated attackers can reach restricted plugin functionality over the network without user interaction, impacting availability of the WordPress site.
Affected Products
- Ecwid by Lightspeed Ecommerce Shopping Cart plugin for WordPress
- Plugin slug: ecwid-shopping-cart

Technical Details for CVE-2026-24613
Vulnerability Analysis
The Ecwid Shopping Cart plugin exposes one or more endpoints that fail to enforce proper authorization checks before executing privileged actions. Classified as Missing Authorization [CWE-862], the issue allows requests to bypass intended access control gating. An unauthenticated remote attacker can issue crafted HTTP requests to the WordPress site and reach functionality that should be restricted to authorized users.
The attack vector is network-based with low complexity and requires no privileges or user interaction. Per the published metrics, the vulnerability impacts availability without directly exposing confidentiality or integrity. EPSS data places the probability of exploitation at 0.06%.
Root Cause
The root cause is incorrectly configured access control security levels within the plugin code. Plugin actions that perform state-changing or resource-intensive operations do not verify the requesting user's capability or nonce before executing. This omission leaves protected handlers reachable by any anonymous HTTP client.
Attack Vector
Exploitation requires network access to the WordPress site hosting the vulnerable plugin. An attacker sends crafted requests to plugin endpoints that lack authorization checks. Because no authentication or user interaction is required, automated scanning and exploitation against exposed WordPress instances are feasible. No verified public proof-of-concept code is available at this time. Refer to the Patchstack WordPress Vulnerability Report for advisory details.
Detection Methods for CVE-2026-24613
Indicators of Compromise
- Unauthenticated HTTP requests to admin-ajax.php or plugin-specific endpoints invoking Ecwid actions from unfamiliar source IPs.
- Anomalous spikes in requests targeting URIs containing ecwid parameters without an authenticated session cookie.
- Unexpected changes in Ecwid plugin state, configuration, or transient WordPress options without corresponding admin login activity.
Detection Strategies
- Inspect web server access logs for requests to plugin handlers that lack a valid wp_nonce or authenticated session.
- Correlate WordPress audit logs with web traffic to identify privileged plugin actions performed without a preceding login event.
- Deploy a Web Application Firewall (WAF) rule that flags Ecwid plugin action parameters originating from unauthenticated clients.
Monitoring Recommendations
- Monitor outbound and inbound traffic volume to the WordPress site for availability degradation consistent with the vulnerability impact.
- Track plugin version inventory across managed WordPress fleets and alert when ecwid-shopping-cart versions <= 7.0.6 are present.
- Enable verbose logging on WordPress hooks invoked by the Ecwid plugin to capture caller context.
How to Mitigate CVE-2026-24613
Immediate Actions Required
- Update the Ecwid Shopping Cart plugin to a version later than 7.0.6 as soon as the vendor publishes a fixed release.
- Audit WordPress installations to identify exposure to the vulnerable plugin and prioritize internet-facing sites.
- Restrict access to /wp-admin/admin-ajax.php from untrusted networks where business requirements allow.
Patch Information
Consult the Patchstack WordPress Vulnerability Report for the latest patched version and vendor remediation guidance. Apply the update through the WordPress plugin manager or via WP-CLI in maintenance windows.
Workarounds
- Deactivate the ecwid-shopping-cart plugin until a fixed version is installed if business operations permit.
- Apply WAF virtual patches blocking unauthenticated requests to Ecwid plugin actions.
- Implement IP allowlisting on administrative endpoints to reduce the unauthenticated attack surface.
# Configuration example: update Ecwid plugin via WP-CLI
wp plugin update ecwid-shopping-cart --version=latest
wp plugin list --name=ecwid-shopping-cart --fields=name,status,version
