Technical details
The Reviews Feed plugin for WordPress (versions prior to 2.6.5) is vulnerable to arbitrary shortcode execution. The vulnerability exists in the dynamic block rendering path (Gutenberg block 'sbr/sbr-feed-block'). When the plugin fetches and caches third-party reviews (e.g., from Google), it fails to sanitize WordPress shortcodes. Because the feed is rendered via a dynamic block, the output is processed by 'do_blocks' and subsequently 'do_shortcode' during the 'the_content' filter execution. An unauthenticated attacker can plant a shortcode in a public review on a connected source; when the plugin displays this review, the shortcode is executed server-side. The impact depends on the shortcodes available on the target site, potentially leading to information disclosure or further exploitation. The classic [reviews-feed] shortcode is not affected.
