Description

The WP Recipe Maker plugin for WordPress is vulnerable to Arbitrary Shortcode Execution in all versions up to, and including, 10.8.1. The vulnerability exists because `WPRM_Metadata::sanitize_metadata()` recursively calls `do_shortcode()` on every scalar field of the recipe's structured metadata array — including the `reviewBody` field, which is populated verbatim from the `comment_content` of approved `wprm-comment-rating` comments — without sanitizing or stripping shortcode tokens before execution; the subsequent `wp_strip_all_tags()` and `strip_shortcodes()` calls operate only on the output string after execution has already fully occurred, providing no protection against server-side shortcode invocation. This makes it possible for unauthenticated attackers to execute arbitrary registered WordPress shortcodes server-side on every recipe page render, causing shortcode output — such as attachment captions, private post fields, or other data exposed by installed shortcodes — to be embedded in the page's JSON-LD `reviewBody` metadata and disclosed to all visitors who load the recipe page. Successful exploitation requires the attacker's rated comment to pass the site's comment approval threshold, either via auto-approval or moderator action, before the injected shortcode begins executing on page loads.
