What the vulnerability does
01Description
The Preload Current Images plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'complete' parameter in the 'preload_progress_bar' shortcode in all versions up to, and including, 1.3. This is due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
02Summary

The vulnerability has a changed scope, meaning injected code can affect other users or site functionality beyond the vulnerable component. An attacker with low-level site access can craft malicious input that executes in other users' browsers, potentially compromising their sessions or stealing data.
