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-2026-20190
Fecha de publicación:
17/06/2026
Idioma:
Inglés
*** Pendiente de traducción *** A vulnerability in Cisco ISE and ISE-PIC could allow an unauthenticated, remote attacker to view sensitive information on an affected device.<br /> <br /> This vulnerability is due to improper authorization checks when a resource is accessed. An attacker could exploit this vulnerability by sending crafted traffic to an affected device. A successful exploit could allow the attacker to gain access to sensitive information, including hashed credentials that could be used in future attacks.

CVE-2026-12515
Fecha de publicación:

Idioma:
Inglés
*** Pendiente de traducción *** A flaw was found in Katello&amp;#39;s of Red Hat Satellite. A content upload functionality where insufficient authorization checks in the ContentUploadsController allowed users with the edit_products permission to query content information for repositories outside the products they were authorized to manage. An authenticated attacker could exploit this issue to determine whether specific content exists within repositories that should otherwise be inaccessible. This issue does not allow unauthorized modification, import, or publication of content.

CVE-2026-20181
Fecha de publicación:
17/06/2026
Idioma:
Inglés
*** Pendiente de traducción *** A vulnerability in Cisco ISE and ISE-PIC could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system of an affected device. To exploit this vulnerability, the attacker must have valid administrative credentials.<br /> <br /> This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to obtain user-level access to the underlying operating system and then elevate privileges to root. In single-node deployments, successful exploitation of this vulnerability could cause the affected ISE node to become unavailable, resulting in a denial of service (DoS) condition. In that condition, endpoints that have not already authenticated would be unable to access the network until the node is restored.

CVE-2026-1288
Fecha de publicación:
17/06/2026
Idioma:
Inglés
*** Pendiente de traducción *** A maliciously crafted RFA file, when converted to FormIt via “Convert RFA to FormIt” in Autodesk Revit, can force a NULL Pointer Dereference vulnerability. Successful exploitation may cause the application to crash, leading to a denial-of-service condition.

CVE-2026-12151
Fecha de publicación:
17/06/2026
Idioma:
Inglés
*** Pendiente de traducción *** Impact:<br /> The undici WebSocket client enforces maxPayloadSize on the cumulative byte count of fragments in a message but does not enforce a limit on the number of fragments. A malicious WebSocket server can stream many small or empty continuation frames that each pass per-frame and cumulative-size validation, collectively causing unbounded memory growth in the client process. The result is memory exhaustion and a denial of service.<br /> <br /> Affected applications are those using the undici WebSocket client (new WebSocket(...)) or the WebSocketStream API that can be induced to connect to an attacker-controlled or compromised WebSocket endpoint.<br /> <br /> All releases starting at undici 6.17.0 are affected.<br /> <br /> Patches: Upgrade to undici &gt;= 6.26.0, &gt;= 7.28.0, or &gt;= 8.5.0. Workarounds:<br /> No workaround is available. The fix must be applied through an upgrade.

Idioma:
Inglés
*** Pendiente de traducción *** Dell PowerFlex Manager, version(s) prior to 5.1.0.1, contain(s) an Improper Authentication vulnerability. An unauthenticated attacker with adjacent network access could potentially exploit this vulnerability, leading to Information disclosure, Information tampering, and Unauthorized access.

CVE-2026-48142
Fecha de publicación:
17/06/2026
Idioma:
Inglés
*** Pendiente de traducción *** NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_charset_module module. When content is served or proxied through a location block with both source_charset utf-8; and a charset directive (for example, charset koi8-r;) configured, remote, unauthenticated attackers can send requests (in conjunction with conditions beyond their control) to cause a heap buffer over-read in the NGINX worker process, leading to limited disclosure of memory or a restart. <br /> <br /> <br /> Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

CVE-2026-47103
Fecha de publicación:
17/06/2026
Idioma:
Inglés
*** Pendiente de traducción *** Python StateMachine versions 3.0.0 before 3.2.0 contains a remote code execution vulnerability that allows attackers to execute arbitrary code by supplying malicious SCXML documents containing crafted `` attributes evaluated unsafely. The SCXMLProcessor passes attacker-controlled expression strings through a call chain ending in Python&amp;#39;s built-in eval() without sandboxing, enabling arbitrary code execution in the context of the hosting process.

CVE-2026-42530
Fecha de publicación:
17/06/2026
Idioma:
Inglés
*** Pendiente de traducción *** NGINX Open Source has a vulnerability in the ngx_http_v3_module module. When NGINX Open Source is configured to use the HTTP/3 QUIC module, a remote unauthenticated attacker along with conditions beyond their control can use a specially crafted HTTP/3 session to reopen a QPACK encoder stream. This may cause a Use-after-Free in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR. <br /> <br /> <br /> Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

CVE-2026-42055
Fecha de publicación:
17/06/2026
Idioma:
Inglés
*** Pendiente de traducción *** NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_proxy_v2_module and ngx_http_grpc_module modules. This vulnerability exists when the proxy_http_version to 2 or grpc_pass directives are used to proxy HTTP/2 traffic, the ignore_invalid_headers directive is set to off, and the large_client_header_buffers directive size is larger than 2 megabytes. A remote, unauthenticated attacker, along with conditions beyond their control, could send large headers while creating an upstream request. This may cause a heap-based buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR. <br /> <br /> <br /> Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
