What the vulnerability does
The PullQuote plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'pullquote' shortcode in all versions up to, and including, 1.0 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
PullQuote versions 1.0 and earlier contain a cross-site scripting vulnerability that allows authenticated users to inject malicious scripts affecting other users. The vulnerability exists because user input is not properly sanitized before being displayed. An attacker with low-level account access can craft malicious content that executes in other users' browsers when they view affected pages.
What an attacker can do
Inject JavaScript that runs in other users' browsers to steal session tokens, redirect them, or deface content.
Potential impact on your site
Authenticated users can compromise other users' sessions or inject malicious content visible across the site.
Conditions required to exploit
Attacker must have a low-privilege account on the site; no user interaction required from the victim.
