CVE-2026-6147 PUBLISHED

LightSync Pro <= 2.1.6 - Authenticated (Author+) Arbitrary File Upload

Assigner: Wordfence
Reserved: 12.04.2026 Published: 05.08.2026 Updated: 05.08.2026

The LightSync Pro plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the rest_replace_media() function in all versions up to, and including, 2.1.6. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
