CVE-2026-16600Network attack vector

Subscriber-level internal data disclosure via unvalidated URL fetch

Published Aug 29, 2026 · Updated Aug 29, 2026

Server-side request forgery in SmartAIPress 1.2.0 and earlier allows remote authenticated users to read arbitrary URL responses. The smartaipress_openai_upload_and_set_featured_image AJAX action omits a capability check and fetches a user-supplied URL without validation. Subscriber-level access is sufficient to retrieve complete responses from internal or external services reachable by the WordPress server.
