AI-suggested

Upgrade the Smush WordPress plugin to version 4.3.6 or later, where this authorization check issue is fixed. There is no indication of an official patch link in the provided data, but the fixed version is explicitly stated. Until upgraded, restrict Author role permissions if possible to limit exposure.

Description

The Smush WordPress plugin versions before 4.3.6 have an authorization flaw where users with the Author role or higher can optimize and restore media attachments owned by other users. This occurs because the plugin only checks a broad upload-files capability rather than verifying specific ownership or authorization for the targeted media. This allows unauthorized modification of other users' media files and consumption of stored backups.
