Description

CVE-2026-118241 is an authorization bypass vulnerability in the Smush WordPress plugin versions before 4.3.6. The plugin fails to verify that a user is authorized to act on a targeted media attachment, only checking a broad upload-files capability. This allows users with the Author role and above to optimize and restore media attachments owned by other users, potentially altering files on disk and consuming stored backups.
