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 is due to a missing capability check on the template count function, allowing subscriber-level attackers to obtain plugin template information. A nonce check is present but 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, consider disabling the template count function until a patch is available to prevent unauthorized use of functionality. Restrict access to the template information to minimize the risk of exploitation.
