Vulnerabilidades

Con el objetivo de informar, advertir y ayudar a los profesionales sobre las últimas vulnerabilidades de seguridad en sistemas tecnológicos, ponemos a disposición de los usuarios interesados en esta información una base de datos con información en castellano sobre cada una de las últimas vulnerabilidades documentadas y conocidas.

Este repositorio con más de 75.000 registros esta basado en la información de NVD (National Vulnerability Database) – en función de un acuerdo de colaboración – por el cual desde INCIBE realizamos la traducción al castellano de la información incluida. En ocasiones este listado mostrará vulnerabilidades que aún no han sido traducidas debido a que se recogen en el transcurso del tiempo en el que el equipo de INCIBE realiza el proceso de traducción.

Se emplea el estándar de nomenclatura de vulnerabilidades CVE (Common Vulnerabilities and Exposures), con el fin de facilitar el intercambio de información entre diferentes bases de datos y herramientas. Cada una de las vulnerabilidades recogidas enlaza a diversas fuentes de información así como a parches disponibles o soluciones aportadas por los fabricantes y desarrolladores. Es posible realizar búsquedas avanzadas teniendo la opción de seleccionar diferentes criterios como el tipo de vulnerabilidad, fabricante, tipo de impacto entre otros, con el fin de acortar los resultados.

Mediante suscripción RSS o Boletines podemos estar informados diariamente de las últimas vulnerabilidades incorporadas al repositorio.

CVE-2026-103424
Fecha de publicación:
10/10/2026
Idioma:
Inglés
*** Pendiente de traducción *** The Anti-Spam by CleanTalk – Spam Protection Without CAPTCHA plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 6.88 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This vulnerability is exploitable once a comment from the attacker's email address has been approved; on default WordPress installations, only the first comment from a given email address is held for moderation, meaning subsequent comments auto-approve and immediately expose the payload to site visitors.

CVE-2026-103889
Fecha de publicación:
10/10/2026
Idioma:
Inglés
*** Pendiente de traducción *** The 3D Product configurator for WooCommerce plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.16.2 via the 'xpv_image' parameter parameter. This is due to missing authentication and nonce checks on the wp_loaded handler combined with no sanitization of the xpv_image POST parameter before it is echoed unescaped into a Dompdf-rendered HTML template with PHP execution enabled. This makes it possible for unauthenticated attackers to execute code on the server. The only nonce and authentication check in the handler is entirely enclosed in a block comment with no replacement, making the endpoint reachable via a single unauthenticated POST to any URL on the site.

CVE-2026-103964
Fecha de publicación:
10/10/2026
Idioma:
Inglés
*** Pendiente de traducción *** The Download Manager plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.3.71 via the 'first_name' parameter. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract the administrator's full Cookie header, including wordpress_logged_in_* session cookies, from the suspension email sent during the administrator's authenticated request, enabling full session hijack and account takeover. Exploitation requires an administrator to perform the Suspend action against the attacker's account, which causes the plugin to synchronously compile and send the suspension email inside the administrator's authenticated HTTP request — making the administrator's session cookies available to the template engine at send time.

*** Pendiente de traducción *** The Form Maker by 10Web – Mobile-Friendly Drag & Drop Contact Form Builder plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'inputs (array key)' parameter in all versions up to, and including, 1.15.48 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

CVE-2026-104021
Fecha de publicación:
10/10/2026
Idioma:
Inglés
*** Pendiente de traducción *** The Fastcache by Host.it plugin for WordPress is vulnerable to Code Injection in all versions up to, and including, 1.7.4 via the `fastcache_settings[cache_cookie_exclude][]` parameter. This is due to the plugin registering the `cache_cookie_exclude` setting via `register_setting()` without a `sanitize_callback`, while `buildSiteHtaccessRules()` applies only `trim()` to each cookie value before interpolating it directly into an Apache `RewriteCond` line — a normalization that strips surrounding whitespace but leaves embedded newlines intact, allowing an attacker to break out of the capture group and append arbitrary directives. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary Apache directives into the site's `.htaccess` file via `file_put_contents()`, enabling server-level configuration changes such as setting `php_value auto_prepend_file` to execute attacker-controlled PHP code on every request.

CVE-2026-104724
Fecha de publicación:
10/10/2026
Idioma:
Inglés
*** Pendiente de traducción *** The FireBox – WooCommerce Popup Builder, Exit Intent Popup, Email Optin & Cart Abandonment plugin for WordPress is vulnerable to generic SQL Injection via FireBox Form Display Condition in all versions up to, and including, 3.1.13 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with author-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. On fresh installations of version 3.1.10 and later, exploitation requires administrator-level access; however, on sites upgraded from a version prior to 3.1.10, the preserveCampaignRoleAccess() migration grants the edit_fireboxes capability to any role that previously held edit_posts, reducing the minimum required privilege to Author-level.

CVE-2026-104735
Fecha de publicación:
10/10/2026
Idioma:
Inglés
*** Pendiente de traducción *** The RSS Aggregator by Feedzy – Feed to Post, Autoblogging, News & YouTube Video Feeds Aggregator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Feedzy Loop Block Feed URL / RSS in all versions up to, and including, 5.2.10 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload is not neutralized at save time because post_content stores only a benign block reference to an external feed URL; the malicious HTML is injected at render time from the attacker-controlled RSS feed title, bypassing any save-time wp_kses filtering.

*** Pendiente de traducción *** The GeoDirectory – WP Business Directory Plugin and Classified Listings Directory plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'email (Contact Email custom field htmlvar_name)' parameter in all versions up to, and including, 2.8.188 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful exploitation requires that an administrator has added and configured the Contact Email custom field to render on the public single-listing output page, and that the administrator subsequently approves the attacker's submitted listing.

CVE-2026-101324
Fecha de publicación:
10/10/2026
Idioma:
Inglés
*** Pendiente de traducción *** The Fluent Forms – Customizable Contact Forms, Survey, Quiz, & Conversational Form Builder plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'any attacker-chosen name matching the {get.NAME} placeholder (PoC uses 'proof')' parameter in all versions up to, and including, 6.2.14 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. Exploitation requires a site administrator to have configured a Custom HTML field on a published form containing a {get.*} SmartCode inside a URL-accepting attribute such as iframe src or a href — a documented Fluent Forms feature.

*** Pendiente de traducción *** The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'regurl' parameter in all versions up to, and including, 3.3.71 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The injected payload only fires for logged-out site visitors, as the vulnerable login-form.php template branch is gated on !is_user_logged_in(); authenticated users viewing the same page are served a different template and are not affected.

CVE-2026-94589
Fecha de publicación:
10/10/2026
Idioma:
Inglés
*** Pendiente de traducción *** The Extensions For CF7 (Contact form 7 Database, Conditional Fields and Redirection) plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 3.4.5 via the extcf7_submit function. This is due to missing file extension, MIME type, and size validation in the signature field's validation_filter(), combined with the absence of PHP-execution guards in the upload directory and a sanitize_file_name() bypass that converts shell.php- into shell.php. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible.
