Low risk5th percentile - higher than 5% of all known CVEs
Summary
The ECS WordPress plugin before version 4.3.8 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. This allows 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.
Risk Assessment
The vulnerability allows unauthorized access to post configurations and plugin settings, potentially leading to data integrity compromise and privilege escalation in WordPress.
Recommendation
It is recommended to immediately update the ECS WordPress plugin to version 4.3.8 or later, which includes permission checks.
