What the vulnerability does

01Description

The Media Sync plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.4.9 via the 'sub_dir' and 'media_items' parameters. This is due to insufficient validation of user-supplied file paths, which are not checked for directory traversal sequences or restricted to the intended uploads directory. This makes it possible for authenticated attackers, with Author-level access and above, to perform actions on files outside of the originally intended directory.

Explanation of Vulnerability in Simple Terms

02Summary

Media Sync versions 1.4.9 and earlier contain a path traversal vulnerability that allows authenticated users to read arbitrary files from the server. An attacker with low-level access can bypass directory restrictions and access sensitive files outside the intended application directory. No user interaction is required to exploit this flaw.

What an attacker can do

03Attacker Capabilities

Potential impact on your site

04Site Impact
