CVE-2026-111740 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 2.7 (low) and affects Post Duplicator; fixed in 3.0.17.

## Summary

The Post Duplicator WordPress plugin, in versions before 3.0.17, does not check whether a logged-in user is allowed to view each post before listing posts of a given type. An attacker with a Contributor-level account or higher can therefore read the titles and hierarchy of other users' draft and private posts.
