CVE-2026-13153: CWE-200 Information Exposure in Gutenberg Essential Blocks
CVE-2026-13153 is an information exposure vulnerability in the Gutenberg Essential Blocks WordPress plugin before version 6.4.0. The plugin does not restrict access to a public REST route, which causes it to expose a non-public WooCommerce per-product sales metric. This allows unauthenticated users to read the lifetime number of units sold for any published product.
AI Analysis
Technical Summary
The Gutenberg Essential Blocks WordPress plugin versions prior to 6.4.0 contain a vulnerability where one of its public REST API routes is improperly secured. This results in over-fetching of a WooCommerce per-product sales metric that is intended to be non-public. Consequently, unauthenticated users can access the lifetime sales count of any published product via this REST endpoint. The vulnerability is classified as CWE-200 (Information Exposure).
Potential Impact
An unauthenticated attacker can retrieve sensitive sales data (lifetime units sold) for any published product on a site using the affected plugin. This exposure of non-public business metrics could lead to competitive intelligence gathering or other privacy concerns. There is no indication of impact on integrity or availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or patch link is provided, users should monitor for updates from the plugin vendor and apply any official updates once available. Until then, restricting access to the affected REST route via custom access controls or disabling the plugin if feasible may reduce exposure.
