What is CVE-2026-9676?
The F4 Post Tree WordPress plugin prior to version 2.0.5 exposes a serious security flaw where it fails to conduct proper capability checks and lacks CSRF/nonce verification on specific AJAX actions. This oversight allows authenticated users with Subscriber-level access and above to alter the parent and menu order of arbitrary posts, potentially leading to unauthorized modifications that can affect site integrity and content management.
Affected Version(s)
F4 Post Tree 0 < 2.0.5
Exploit Proof of Concept (PoC)
