Name of the Vulnerable Software and Affected Versions The Essential Blocks plugin for WordPress versions up to, and including, 4.0.6

Description The issue allows unauthorized use of functionality due to a missing capability check on the get function. This enables subscriber-level attackers to obtain plugin settings. Although a nonce check is present, it is only executed when a nonce is provided, and not providing a nonce results in the nonce verification being skipped.

Recommendations For versions up to, and including, 4.0.6, update to a version that includes a capability check on the get function to prevent unauthorized access. As a temporary workaround, consider implementing additional access controls to restrict subscriber-level access to plugin settings until a patch is available.
