Vulnerability Overview

The Extended Post Status plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the wp_insert_post_data function in versions up to, and including, 1.0.19. This makes it possible for authenticated attackers, with contributor-level access and above, to set their own posts to the 'published' status via the extended post status metabox.

Technical Analysis

REMEDIATION: Update to version 1.0.20, or a newer patched version --- IDENTIFIER: CWE-862 (Missing Authorization) The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
