Vulnerabilidades

Con el objetivo de informar, advertir y ayudar a los profesionales sobre las ultimas 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 ultimas 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 ultimas vulnerabilidades incorporadas al repositorio.

Idioma:

*** Pendiente de traducción *** The Posts map plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'name' shortcode attribute in all versions up to, and including, 0.1.3 due to insufficient input sanitization and output escaping on user supplied attributes. 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.

*** Pendiente de traducción *** The Simple Random Posts Shortcode plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'container_right_width' attribute of the 'simple_random_posts' shortcode in all versions up to, and including, 0.3 due to insufficient input sanitization and output escaping on user supplied attributes. 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.

CVE-2026-6294

Fecha de publicación:

Idioma:
Inglés
*** Pendiente de traducción *** The Google PageRank Display plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to and including 1.4. This is due to missing nonce validation in the gpdisplay_option() function, which handles the plugin settings page. The settings form does not include a wp_nonce_field(), and the form handler does not call check_admin_referer() or wp_verify_nonce() before processing the POST request. This makes it possible for unauthenticated attackers to trick a logged-in administrator into submitting a crafted request that changes the plugin's settings (stored via update_option()), such as the display style used to render the PageRank badge.

CVE-2026-6396

Idioma:
Inglés
*** Pendiente de traducción *** The Fast & Fancy Filter – 3F plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to and including 1.2.2. This is due to missing nonce verification in the saveFields() function, which handles the fff_save_settins AJAX action. This makes it possible for unauthenticated attackers to modify plugin filter settings, update arbitrary options, or create new filter posts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

CVE-2026-6843

Fecha de publicación:

Idioma:
Inglés
*** Pendiente de traducción *** A flaw was found in nano. A local user could exploit a format string vulnerability in the `statusline()` function. By creating a directory with a name containing `printf` specifiers, the application attempts to display this name, leading to a segmentation fault (SEGV). This results in a Denial of Service (DoS) for the `nano` application.

CVE-2026-4142

Fecha de publicación:
22/04/2026
Idioma:
Inglés
*** Pendiente de traducción *** The Sentence To SEO (keywords, description and tags) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Permanent keywords' field in all versions up to and including 1.0. This is due to insufficient input sanitization and output escaping. The plugin reads user input via filter_input_array(INPUT_POST) which applies no HTML sanitization (FILTER_DEFAULT), stores it unsanitized to the WordPress options table via update_option(), and then outputs the stored value directly into a textarea element without any escaping using PHP short echo tags (). An attacker can break out of the textarea element using a closing tag and inject arbitrary HTML/JavaScript. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the plugin's settings page.

CVE-2026-4279

Fecha de publicación:

Idioma:
Inglés
*** Pendiente de traducción *** The Bread & Butter plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'breadbutter-customevent-button' shortcode in all versions up to, and including, 8.2.0.25. This is due to insufficient input sanitization and output escaping on the 'event' shortcode attribute. The customEventShortCodeButton() function takes the 'event' attribute value and directly interpolates it into a JavaScript string within an onclick HTML attribute without applying esc_attr() or esc_js(). Notably, the sister function customEventShortCode() properly uses esc_js() for the same attribute, but this was omitted in the button variant. 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 the page and clicks the injected button.

CVE-2026-4280

Fecha de publicación:
22/04/2026
Idioma:
Inglés
*** Pendiente de traducción *** The Breaking News WP plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 1.3. This is due to the brnwp_ajax_form AJAX endpoint lacking both authorization checks and CSRF verification, combined with insufficient path validation when the brnwp_theme option value is passed directly to an include() statement in the brnwp_show_breaking_news_wp() shortcode handler. While sanitize_text_field() is applied to user input, it does not strip directory traversal sequences (../). This makes it possible for authenticated attackers, with Subscriber-level access and above, to overwrite the brnwp_theme option with a directory traversal payload (e.g., ../../../../etc/passwd) and subsequently trigger file inclusion of arbitrary files on the server when the shortcode is rendered.

*** Pendiente de traducción *** The CI HUB Connector plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'id' attribute of the `cihub_metadata` shortcode in all versions up to, and including, 1.2.106 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.

*** Pendiente de traducción *** The Text Snippets plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `ts` shortcode in all versions up to, and including, 0.0.1 due to insufficient input sanitization and output escaping on user supplied attributes. 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.

*** Pendiente de traducción *** The Zypento Blocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Table of Contents block in all versions up to, and including, 1.0.6. This is due to the front-end TOC rendering script reading heading text via `innerText` and inserting it into the page using `innerHTML` without proper sanitization. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
