This is due to the handle_email_verification_page() function constructing a shortcode string from user-supplied GET parameters (token, email) and passing it to do_shortcode() without properly sanitizing square bracket characters, combined with missing authorization checks on the init hook. While sanitize_text_field() and esc_attr() are applied, neither function strips or escapes square bracket characters ([ and ]). WordPress's shortcode regex uses [^\\]\\/]* to match content inside shortcode tags, meaning a ] character in the token value prematurely closes the shortcode tag. This makes it possible for unauthenticated attackers to inject and execute arbitrary registered shortcodes by crafting a malicious token parameter containing ] followed by arbitrary shortcode syntax."},{"lang":"es","value":"El plugin Instant Popup Builder para WordPress es vulnerable a la Ejecución Arbitraria de Shortcode No Autenticada en todas las versiones hasta la 1.1.7 inclusive. Esto se debe a que la función handle_email_verification_page() construye una cadena de shortcode a partir de parámetros GET proporcionados por el usuario (token, email) y la pasa a do_shortcode() sin sanear correctamente los caracteres de corchete, combinado con la falta de comprobaciones de autorización en el hook init. Aunque se aplican sanitize_text_field() y esc_attr(), ninguna de las funciones elimina o escapa los caracteres de corchete ([ y ]). La expresión regular de shortcode de WordPress utiliza [^\\]\\/]* para hacer coincidir el contenido dentro de las etiquetas de shortcode, lo que significa que un carácter ] en el valor del token cierra prematuramente la etiqueta de shortcode. Esto hace posible que atacantes no autenticados inyecten y ejecuten shortcodes registrados arbitrarios al crear un parámetro de token malicioso que contenga ] seguido de sintaxis de shortcode arbitraria."}],"id":"CVE-2026-3475","lastModified":"2026-06-17T10:43:38.663","metrics":{"cvssMetricV31":[{"cvssData":{"attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"NONE","baseScore":5.3,"baseSeverity":"MEDIUM","confidentialityImpact":"NONE","integrityImpact":"LOW","privilegesRequired":"NONE","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"exploitabilityScore":3.9,"impactScore":1.4,"source":"security@wordfence.com","type":"Secondary"}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"id":"CVE-2026-3475","options":[{"exploitation":"none"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","timestamp":"2026-03-19T13:44:02.852369Z","version":"2.0.3"}}]},"published":"2026-03-19T08:16:19.327","references":[{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/instant-popup-builder/tags/1.1.6/public/class-instant-popup-subscription-public.php#L1761"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/instant-popup-builder/tags/1.1.6/public/class-instant-popup-subscription-public.php#L1772"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/instant-popup-builder/trunk/public/class-instant-popup-subscription-public.php#L1761"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/instant-popup-builder/trunk/public/class-instant-popup-subscription-public.php#L1772"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3477334%40instant-popup-builder&new=3477334%40instant-popup-builder&sfp_email=&sfph_mail="},{"source":"security@wordfence.com","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/979962e3-9052-4dc9-94d0-3ec8de3d5460?source=cve"}],"sourceIdentifier":"security@wordfence.com","vulnStatus":"Deferred","weaknesses":[{"description":[{"lang":"en","value":"CWE-862"}],"source":"security@wordfence.com","type":"Secondary"}]}
