CVE-2023-2085
Full vulnerability record from the local CVENow database.
Description
The Essential Blocks plugin for WordPress is vulnerable to unauthorized use of functionality due to a missing capability check on the templates function in versions up to, and including, 4.0.6. This makes it possible for subscriber-level attackers to obtain plugin template information. While a nonce check is present, it is only executed when a nonce is provided. Not providing a nonce results in the nonce verification to be skipped. There is no capability check.

Esto hace posible que atacantes con nivel de suscriptor obtengan información de plantillas del plugin. Aunque una verificación de nonce está presente, solo se ejecuta cuando se proporciona un nonce. No proporcionar un nonce resulta en que la verificación del nonce sea omitida. No hay verificación de capacidad."
