Vulnerability Overview

WordPress Core is vulnerable to Clickjacking in versions 6.6 through 7.1.3 because Interactivity API bindings allow Contributor-supplied content to replace KSES-approved object attributes and load otherwise restricted same-origin administrative pages. This makes it possible for authenticated attackers, with Contributor-level access and above, to embed administrative interfaces in post content and trick a privileged user into performing an unintended action when interacting with a crafted page.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed.

CWE-1021: Improper Restriction of Rendered UI Layers or Frames

The web application does not restrict or incorrectly restricts frame objects or UI layers that belong to another application or domain.

Remediation

Update to one of the following versions, or a newer patched version: 6.6.11, 6.7.11, 6.8.12, 6.9.11, 7.0.8, 7.1.4
