Description

The ECS WordPress plugin before 4.3.10 does not perform ownership or post-status checks when one of its dynamic repeater data sources reads custom field values from a user-supplied post identifier, allowing users with a contributor-level account or above to read custom field values and post metadata from posts they do not own, including private and draft ones.
