Medium severity, CVSS 6.4. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products
