CVE-2026-1405
High PUBLISHEDSlider Future <= 1.0.5 - Unauthenticated Arbitrary File Upload
Not yet in CISA KEV
Recommended Action
Prioritize remediation. Validate affected assets and apply vendor fixes on an accelerated timeline.
At a Glance
The Slider Future plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'slider_future_handle_image_upload' function in all versions up to, and including, 1.0.5. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
