Gutenberg Essential Blocks
Monthly
Unauthenticated information disclosure in the Gutenberg Essential Blocks WordPress plugin before 6.4.0 exposes published content from custom post types that site administrators deliberately registered as non-public. The plugin's public REST API route queries arbitrary post types supplied by the caller without first verifying their visibility setting, bypassing the access control intent of the post type registration. A publicly available proof-of-concept exists; EPSS sits at 0.14% (4th percentile) suggesting exploitation remains rare despite automatable conditions, and the vulnerability is not currently listed in the CISA KEV catalog.
Unauthenticated information disclosure in Gutenberg Essential Blocks for WordPress (versions before 6.4.0) exposes WooCommerce per-product lifetime sales unit counts to any internet user via an unrestricted public REST API route. The plugin over-fetches a non-public WooCommerce metric and surfaces it in the REST response without access control enforcement, meaning competitors, scrapers, or threat actors can query sales volumes for any published product on affected stores. A publicly available proof-of-concept exploit exists per WPScan, and SSVC assessment confirms the attack is automatable; however, EPSS sits at just 0.14% (4th percentile), indicating limited observed exploitation at time of analysis.
