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-2026-66913

Fecha de publicación:
28/07/2026
Idioma:
Inglés
*** Pendiente de traducción *** Lookyloo did not enforce limits on the decompressed size of uploaded capture archives and compressed HAR files.<br /> <br /> An attacker could submit a specially crafted ZIP, gzip, or zlib-compressed capture containing data that expands to a very large size during processing. Because the application decompressed this content directly in memory without first limiting the output size, processing the malicious capture could exhaust available memory, terminate a web or worker process, or make the Lookyloo instance unavailable.<br /> <br /> The vulnerability affects both full Lookyloo capture archive imports and API submissions containing gzip-compressed HAR data. Repeated exploitation could cause a persistent denial-of-service condition until the affected processes or instance are restarted.<br /> <br /> The patch introduces:<br /> <br /> * A 1 GB cumulative uncompressed-size limit for imported capture archives.<br /> * Size-limited gzip and zlib decompression for compressed HAR files.<br /> * Explicit detection and handling of suspected zip bombs.<br /> * An HTTP 400 response when an oversized compressed HAR file is submitted through the API.

CVE-2026-66918

Fecha de publicación:
28/07/2026
Idioma:
Inglés
*** Pendiente de traducción *** Pivotick fails to sanitize attacker-controlled SVG markup supplied through the per-node style.svgIcon property before inserting it into the document.<br /> <br /> When rendering a graph node, the vulnerable code assigns the SVG icon markup directly to the innerHTML property of a live SVG element. An attacker able to influence graph data can provide crafted markup containing executable event handlers, such as an element with an onerror attribute.<br /> <br /> When a victim loads or renders the malicious graph, the payload may execute arbitrary JavaScript in the security context of the application embedding Pivotick. Successful exploitation could allow the attacker to access application data available to the victim, modify displayed content, or perform actions using the victim’s authenticated session.<br /> <br /> Exploitation requires an application using Pivotick to render graph data that is controlled or modified by an attacker.

CVE-2026-66919

Fecha de publicación:
28/07/2026
Idioma:
Inglés
*** Pendiente de traducción *** Pivotick contains a cross-site scripting vulnerability in the inspect and edit node modals. Node labels and descriptions originating from graph data were interpolated directly into HTML used to construct the modal headers.<br /> <br /> An attacker able to supply or modify graph data could insert a malicious HTML or JavaScript payload into a node’s label or description. The payload would be parsed and executed in the application’s origin when a user opened the affected node’s inspect or edit modal.<br /> <br /> Successful exploitation could allow the attacker to access information available to the victim, modify application data, or perform actions using the victim’s active session.<br /> <br /> The vulnerability has been addressed by creating the modal elements without embedding graph data in HTML and assigning node labels and descriptions through textContent.

*** Pendiente de traducción *** [This CNA information record relates to multiple CVEs; the<br /> text explains which aspects/vulnerabilities correspond to which CVE.]<br /> <br /> With the introduction of Grant Table v2 came the requirement to be able to<br /> switch between versions.

*** Pendiente de traducción *** When grant-copy operations are processed, the respective grant may or may<br /> not already be in use by another operation (a mapping or another copy).<br /> For all copy operations the referenced guest frame is looked up. When<br /> another operation is already active for the grant (the grant is "pinned"),<br /> what is being supplied back to actually carry out permission checks and<br /> copy operation may not be consistent: The permission check may be carried<br /> out on a page different from the one involved in the copy.
