Name of the Vulnerable Software and Affected Versions The Thumbnail Slider With Lightbox plugin for WordPress version 1.0

Description The issue is due to missing or incorrect nonce validation on the addedit functionality. This allows unauthenticated attackers to upload arbitrary files via a forged request if they can trick a site administrator into performing an action such as clicking on a link.

Recommendations For version 1.0, consider disabling the addedit functionality until a patch is available to prevent exploitation.

At the moment, there is no information about a newer version that contains a fix for this vulnerability.
