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
The ECS WordPress plugin versions prior to 4.3.10 do not verify ownership or post status when reading custom field values from a user-supplied post identifier in its dynamic repeater data sources. This flaw permits users with contributor-level access or above to access custom field data and metadata from posts they do not own, including private and draft posts, resulting in unauthorized information disclosure. The vulnerability is classified as CWE-200 (Information Exposure).
Potential Impact
An attacker with contributor-level or higher privileges can read sensitive custom field values and metadata from posts they do not own, including private and draft posts. This leads to unauthorized disclosure of potentially sensitive information. There is no impact on integrity or availability reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch information is currently available. Until a patch is released, restrict contributor-level access and review user permissions carefully to limit exposure.
