What the vulnerability does
The Twitter Feeds plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'tweet_title' parameter in the 'TwitterFeeds' 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
Twitter Feeds versions 1.0.0 and earlier contain a cross-site scripting vulnerability that allows authenticated users to inject malicious scripts affecting other users. The vulnerability has a changed scope, meaning the impact extends beyond the vulnerable component itself. Low-privileged accounts can exploit this without user interaction to compromise site integrity and read sensitive data.
What an attacker can do
Inject malicious scripts that execute in other users' browsers and read or modify site data.
Potential impact on your site
Authenticated users can inject scripts affecting other visitors; data theft and site defacement possible.
Conditions required to exploit
Attacker must have a low-privileged account on the site; no user interaction required.
