CVE-2024-6256: Smashballoon Feeds For YouTube

Medium severity, CVSS 5.4. EPSS: 0.4% chance of exploitation in the next 30 days.

The Feeds for YouTube (YouTube video, channel, and gallery plugin) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'youtube-feed' shortcode in all versions up to, and including, 2.2.1 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.

Affected products

• Smashballoon Feeds For YouTube: before 2.2.2 (fixed in 2.2.2)
