WP Recipe Maker <=10.8.1 Arbitrary Shortcode Exec via reviewBody
CVE-2026-89274 Published on September 19, 2026
WP Recipe Maker <= 10.8.1 - Unauthenticated Arbitrary Shortcode Execution via Recipe Comment Content
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.
