Technical Analysis
CVE-2026-78150 is an authorization bypass vulnerability in the Smart Post WordPress plugin prior to version 4.0.8. The plugin fails to verify the type, ownership, or status of posts requested for duplication. As a result, users with contributor-level permissions or higher can copy private or password-protected posts into drafts they control, thereby gaining access to content and metadata that should be inaccessible to them. This vulnerability is classified under CWE-639 (Authorization Bypass Through User-Controlled Key).
Potential Impact
The vulnerability allows unauthorized disclosure of private or password-protected post content and metadata to users with contributor privileges or higher. It does not impact integrity or availability but compromises confidentiality of restricted posts.
Mitigation Recommendations
No official patch or remediation guidance is currently available. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, restrict contributor-level access carefully and monitor plugin updates for a security patch.
