Impact

The Image Optimizer WordPress plugin before version 1.7.7 fails to enforce its intended capability checks on several read‑only REST routes, allowing any authenticated user to retrieve attachment metadata and site‑wide statistics that are intended for administrators only. This disclosure can expose file paths, image dimensions, upload dates, and aggregated usage metrics, compromising the site’s confidentiality.

Affected Systems

The vulnerability affects the WordPress plugin Image Optimizer by Elementor running any version prior to 1.7.7. Sites with older versions of this plugin are exposed to the flaw.

Risk and Exploitability

Authentication alone is sufficient to exploit the flaw, making it trivially exploitable by anyone with a standard user account. The vulnerability has a CVSS score of 4.3 and an EPSS score of < 1%, and is not listed in the CISA KEV catalog, indicating no known public exploitation yet, but the potential for data disclosure remains high for any site that accepts authenticated users.
