What the vulnerability does
The Biagiotti Core plugin for WordPress is vulnerable to Stored Cross-Site Scripting via shortcodes in versions up to, and including, 2.1.3 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
Biagiotti Core versions up to 2.1.3 contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has a changed scope, meaning injected code can affect other users and site functionality. An attacker with low-level account access can craft malicious input that executes in other users' browsers when they view affected pages.
What an attacker can do
Inject JavaScript that runs in other users' browsers, potentially stealing session tokens or performing actions on their behalf.
Potential impact on your site
Authenticated users can be compromised; attackers may steal admin credentials or modify site content through victim accounts.
Conditions required to exploit
Attacker must have a low-privilege account on the site (e.g., subscriber or contributor role).
