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-2026-8924

Fecha de publicación:

03/07/2026

Idioma:

Inglés

*** Pendiente de traducción *** A flaw in curl’s cookie parsing logic allows a malicious HTTP server to set &#39;super cookies&#39; that bypass the Public Suffix List check. This enables an attacker-controlled origin to inject cookies that curl subsequently scopes and transmits to unrelated third-party domains.

CVE-2026-8925

Fecha de publicación:

03/07/2026

Idioma:

Inglés

*** Pendiente de traducción *** The curl logic that works with SASL authentication could end up cleaning up the GSASL context *twice* without clearing the pointer in between, making it `free()` the same pointer twice.

CVE-2026-10536

Fecha de publicación:

03/07/2026

Idioma:

Inglés

*** Pendiente de traducción *** A use-after-free vulnerability exists in libcurl when an application configures an HTTP/2 stream-dependency tree via `CURLOPT_STREAM_DEPENDS` or `CURLOPT_STREAM_DEPENDS_E`, subsequently invokes `curl_easy_reset()`, and finally terminates the handle with `curl_easy_cleanup()`. During this final cleanup phase, libcurl attempts to access and modify an internal structure that was already freed during the reset operation.

CVE-2026-11352

Fecha de publicación:

03/07/2026

Idioma:

Inglés

*** Pendiente de traducción *** An issue in curl’s QUIC UDP receive function allows a malicious HTTP/3 server to trigger a remote denial of service against a curl or libcurl client. Because the helper function discards zero-length UDP datagrams before counting them toward the per-call packet budget, a connected QUIC peer can continuously stream empty datagrams to indefinitely stall the client.

CVE-2026-11564

Fecha de publicación:

03/07/2026

Idioma:

Inglés

*** Pendiente de traducción *** libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup. An easy handle that first uses default native CA trust can continue trusting the native platform store after the application switches that same handle to custom CA material for a later transfer.

CVE-2026-11586

Fecha de publicación:

03/07/2026

Idioma:

Inglés

*** Pendiente de traducción *** By default, curl automatically responds to WebSocket PING frames. Because curl lacks an upper bound on memory allocation for unacknowledged frames, a malicious server can exhaust all available memory by flooding curl with rapid, sequential PING messages.

CVE-2026-11856

Fecha de publicación:

03/07/2026

Idioma:

Inglés

*** Pendiente de traducción *** Successfully using libcurl to do a transfer to a specific HTTP origin (`hostA`) with **Digest** authentication and then changing the origin to a different one (`hostB`) for a second transfer, reusing the same handle, makes libcurl wrongly pass on the `Authorization:` header field meant for `hostA`, to `hostB`.

CVE-2026-9626

Fecha de publicación:

03/07/2026

Idioma:

Inglés

*** Pendiente de traducción *** The JSON API User plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the &#39;content&#39; parameter of the post_comment API endpoint in versions up to, and including, 4.1.0 This is due to insufficient input sanitization in the post_comment() function, which passes the attacker-controlled comment_content value directly to wp_insert_comment() without applying any HTML sanitization, and additionally allows the caller to set comment_approved=1 to self-approve the comment and bypass moderation. 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.

CVE-2026-9725

Fecha de publicación:

03/07/2026

Idioma:

Inglés

*** Pendiente de traducción *** The Printcart Web to Print Product Designer for WooCommerce plugin for WordPress is vulnerable to Arbitrary File Deletion in versions up to, and including, 2.5.2 This is due to insufficient path validation in the store_design_data() function, which constructs a filesystem path from the user-supplied &#39;nbd_item_key&#39; POST parameter sanitized only with sanitize_text_field() — which does not strip path traversal sequences — and then passes that path directly to Nbdesigner_IO::delete_folder() and PHP&#39;s rename(). The nonce protecting the nbd_save_customer_design AJAX action is freely obtainable by unauthenticated users via the nbd_check_use_logged_in endpoint. This makes it possible for unauthenticated attackers to delete arbitrary files on the affected site&#39;s server which may make remote code execution possible.

CVE-2026-8489

Fecha de publicación:

03/07/2026

Idioma:

Inglés

*** Pendiente de traducción *** The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the &#39;about_me&#39; parameter in all versions up to, and including, 2.11.4 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.

CVE-2026-8892

Fecha de publicación:

03/07/2026

Idioma:

Inglés

*** Pendiente de traducción *** The CM Business Directory – Optimise and showcase local business plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Business Address Meta Fields in all versions up to, and including, 1.5.7 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. Because the malicious payload is stored in post meta rather than post_content, WordPress&#39;s unfiltered_html capability restriction does not apply, meaning contributors who lack that capability can still inject executable HTML via the address meta fields such as cmbd_address, cmbd_cityTown, cmbd_stateCounty, cmbd_postalcode, cmbd_region, and cmbd_country.

CVE-2026-9180

Fecha de publicación:

03/07/2026

Idioma:

Inglés

*** Pendiente de traducción *** The MotoPress Appointment Booking plugin for WordPress is vulnerable to Authorization Bypass Through User-Controlled Key in all versions up to, and including, 2.4.4. This is due to the `POST /motopress/appointment/v1/bookings` REST endpoint being registered with `&#39;permission_callback&#39; => &#39;__return_true&#39;`, allowing unauthenticated access, while the `createBooking` handler in `BookingsRestController.php` accepts an attacker-supplied `payment_details.booking_id` value and loads the referenced booking via `findById()` without verifying that the caller owns or has any rights to that booking. This makes it possible for unauthenticated attackers to overwrite the customer name, email address, phone number, and `customer_id` of any non-confirmed victim booking by submitting a request with no reservation items, causing `BookingService::createBooking()` to load the existing victim booking object and persist it with attacker-controlled customer data. Victim booking IDs can be harvested prior to exploitation without authentication by querying the also-publicly-accessible `GET /motopress/appointment/v1/bookings/reservations` endpoint with a guessable `service_id` and date range, and only bookings whose status is not `STATUS_CONFIRMED` (e.g., pending or auto-draft) are valid targets.
