{"id":"CVE-2026-89274","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-89274","generatedAt":"2026-09-20T11:41:00.464Z","title":"The WP Recipe Maker plugin for WordPress is vulnerable to Arbitrary Shortcode Execution in all versions up to, and including, 10.8.1.","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.","published":"2026-09-19T03:17:17.000Z","lastModified":"2026-09-19T14:17:03.000Z","status":"Received","sourceIdentifier":"security@wordfence.com","cvss":{"version":"3.1","score":9.1,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"},"cwe":["CWE-94"],"affected":[],"epss":{"score":0.00379,"percentile":0.31839,"date":"2026-09-19","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.38%).
