What the vulnerability does
The ThemeLoom Widgets plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'los_showposts' shortcode in all versions up to, and including, 1.8.5 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
ThemeLoom Widgets versions 1.8.5 and earlier contain a cross-site scripting vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has a changed scope, meaning the impact can extend beyond the vulnerable component itself. Site administrators should update to a version newer than 1.8.5 to mitigate this risk.
What an attacker can do
Inject and execute malicious JavaScript in the site, affecting other users and potentially the site itself.
Potential impact on your site
Authenticated attackers can inject scripts that compromise other users' sessions, steal data, or deface content.
Conditions required to exploit
Attacker must have a low-privilege authenticated account (e.g., contributor or subscriber role).
