ECS < 4.3.8 - Contributor+ Arbitrary Post Binding and Global Preset Modification via Dynamic Repeater Handlers

Description

The plugin does not have capability or ownership checks on its dynamic repeater actions, relying only on a nonce available to any user who can open the page builder, allowing users with a contributor-level account or above to read, alter and delete the binding configuration of posts they do not own and to change the plugin's site-wide presets.
