What the vulnerability does
The SP Blog Designer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'design' attribute of the `wpsbd_post_carousel` shortcode in all versions up to, and including, 1.0.0 due to insufficient input sanitization and output escaping. 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
SP Blog Designer versions 1.0.0 and earlier contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has scope change, meaning injected code can affect other users or components beyond the vulnerable feature. An attacker with low-level account access can craft malicious input that executes in other users' browsers, potentially stealing session data or performing actions on their behalf.
What an attacker can do
Inject malicious scripts that execute in other users' browsers and affect other site components.
Potential impact on your site
Authenticated users can inject scripts affecting other users' sessions and site functionality.
Conditions required to exploit
Attacker must have a low-privilege account on the site; no user interaction required.
