CVE-2026-19613: CWE-200 Information Exposure in ECS
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.
AI Analysis
Technical Summary
CVE-2026-19613 is an information exposure vulnerability (CWE-200) in the ECS WordPress plugin prior to version 4.3.10. The plugin's dynamic repeater data sources fail to perform ownership or post-status checks when accessing custom field values based on a user-supplied post identifier. As a result, users with contributor-level permissions or above can access custom field data and metadata from posts they do not own, including those marked private or draft.
Potential Impact
This vulnerability allows unauthorized disclosure of sensitive post metadata and custom field values. Users with contributor-level privileges can access information from posts they should not have visibility into, potentially exposing confidential or private content.
Mitigation Recommendations
