CVE-2023-31090Network attack vector

Authenticated code execution via unchecked ZIP contents

Published Apr 24, 2024 · Updated Apr 28, 2026

Arbitrary file upload in Unlimited Elements For Elementor 1.5.60 and earlier allows remote authenticated users to upload web shells. The File Manager extracts ZIP entries without validating their file types, allowing executable PHP content to reach the site's server. Contributor-level access is sufficient; successful placement of a web shell grants code execution in the WordPress server context.
