CVE-2026-16274: CWE-862 Missing Authorization in Classified Listing
The Classified Listing WordPress plugin before 5.4.4 does not perform a capability or ownership check on an AJAX action that returns a post's content, allowing users with contributor-level access and above to read the content of any post, page, or custom post type on the site — including drafts, pending, and private posts owned by other users — regardless of ownership.
AI Analysis
Technical Summary
CVE-2026-16274 is a missing authorization vulnerability (CWE-862) in the Classified Listing WordPress plugin prior to version 5.4.4. The plugin fails to verify user capabilities or ownership when processing an AJAX request that returns post content. As a result, authenticated users with contributor-level permissions or higher can access the content of any post, including drafts, pending, and private posts belonging to other users. This bypasses intended access controls and can lead to unauthorized disclosure of sensitive content. No patch or official remediation has been documented at this time.
Potential Impact
Users with contributor-level access or higher can read the content of any post on the affected WordPress site, including unpublished drafts, pending posts, and private posts owned by other users. This unauthorized access can lead to disclosure of sensitive or confidential information that was not intended to be publicly or broadly accessible.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access where possible and monitor for plugin updates addressing this issue.
