CVE-2026-4885 is a critical vulnerability in the Piotnet Addons for Elementor Pro WordPress plugin that allows unauthenticated attackers to upload arbitrary files due to insufficient file type validation. The plugin's incomplete blacklist blocks only a few dangerous extensions but allows others like . phar and . phtml, which can lead to remote code execution if a file upload field is present in a form. This affects all versions up to and including 7.1.70. No official patch or remediation guidance is currently available from the vendor.
