The ECS WordPress plugin before 4.3.13 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 ECS WordPress plugin before 4.3.13's site-wide presets.
