Description
The BuddyHolis ListSearch plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'listsearch' shortcode in all versions up to, and including, 1.1 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.

Mitigation Strategies

[{'type': 'paragraph', 'content': 'The BuddyHolis ListSearch plugin has been temporarily closed and removed from download availability pending a full security review.'}, {'type': 'paragraph', 'content': 'As an immediate mitigation step, you should disable or uninstall the BuddyHolis ListSearch plugin if it is currently active on your WordPress site to prevent exploitation.'}, {'type': 'paragraph', 'content': "Additionally, restrict contributor-level and higher users from adding or modifying content that uses the 'listsearch' shortcode until a patched version is released."}] [1]

Impact Analysis

This vulnerability allows attackers with contributor-level access to inject malicious scripts into web pages viewed by other users. This can lead to theft of user credentials, session hijacking, defacement of the website, or distribution of malware.

Since the vulnerability is a Stored Cross-Site Scripting issue, the malicious code persists on the site and affects all users who visit the compromised pages, increasing the potential impact.
