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-2026-22734

*** Pendiente de traducción *** Cloud Foundry UUA is vulnerable to a bypass that allows an attacker to obtain a token for any user and gain access to UAA-protected systems. This vulnerability exists when SAML 2.0 bearer assertions are enabled for a client, as the UAA accepts SAML 2.0 bearer assertions that are neither signed nor encrypted. This issue affects UUA from v77.30.0 to v78.7.0 (inclusive) and it affects CF Deployment from v48.7.0 to v54.14.0 (inclusive).

*** Pendiente de traducción *** SiYuan is an open-source personal knowledge management system. In versions 3.6.3 and below, Mermaid diagrams are rendered with securityLevel set to "loose", and the resulting SVG is injected into the DOM via innerHTML. This allows attacker-controlled javascript: URLs in Mermaid code blocks to survive into the rendered output. On desktop builds using Electron, windows are created with nodeIntegration enabled and contextIsolation disabled, escalating the stored XSS to arbitrary code execution when a victim opens a note containing a malicious Mermaid block and clicks the rendered diagram node. This issue has been fixed in version 3.6.4.

CVE-2026-40259

*** Pendiente de traducción *** SiYuan is an open-source personal knowledge management system. In versions 3.6.3 and below, the /api/av/removeUnusedAttributeView endpoint is protected only by generic authentication that accepts publish-service RoleReader tokens. The handler passes a caller-controlled id directly to a model function that unconditionally deletes the corresponding attribute view file from the workspace without verifying that the caller has write privileges or that the target attribute view is actually unused. An authenticated publish-service reader can permanently delete arbitrary attribute view definitions by extracting publicly exposed data-av-id values from published content, causing breakage of database views and workspace rendering until manually restored. This issue has been fixed in version 3.6.4.

*** Pendiente de traducción *** SiYuan is an open-source personal knowledge management system. In versions 3.6.3 and prior, the /api/av/removeUnusedAttributeView endpoint constructs a filesystem path using the user-controlled id parameter without validation or path boundary enforcement. An attacker can inject path traversal sequences such as ../ into the id value to escape the intended directory and delete arbitrary .json files on the server, including global configuration files and workspace metadata. This issue has been fixed in version 3.6.4.

CVE-2026-40253
Fecha de publicación:
16/04/2026
Idioma:
Inglés
*** Pendiente de traducción *** openCryptoki is a PKCS#11 library and provides tooling for Linux and AIX. In versions 3.26.0 and below, the BER/DER decoding functions in the shared common library (asn1.c) accept a raw pointer but no buffer length parameter, and trust attacker-controlled BER length fields without validating them against actual buffer boundaries. All primitive decoders are affected: ber_decode_INTEGER, ber_decode_SEQUENCE, ber_decode_OCTET_STRING, ber_decode_BIT_STRING, and ber_decode_CHOICE. Additionally, ber_decode_INTEGER can produce integer underflows when the encoded length is zero. An attacker supplying a malformed BER-encoded cryptographic object through PKCS#11 operations such as C_CreateObject or C_UnwrapKey, token loading from disk, or remote backend communication can trigger out-of-bounds reads. This affects all token backends (Soft, ICA, CCA, TPM, EP11, ICSF) since the vulnerable code is in the shared common library. A patch is available thorugh commit ed378f463ef73364c89feb0fc923f4dc867332a3.

*** Pendiente de traducción *** AdonisJS HTTP Server is a package for handling HTTP requests in the AdonisJS framework. In @adonisjs/http-server versions prior to 7.8.1 and 8.0.0-next.0 through 8.1.3, and @adonisjs/core versions prior to 7.4.0, the response.redirect().back() method reads the Referer header from the incoming HTTP request and redirects to that URL without validating the host.An attacker who can influence the Referer header can cause the application to redirect users to a malicious external site. This affects all AdonisJS applications that use response.redirect().back() or response.redirect('back'). This issue has been fixed in versions 7.8.1 and 8.2.0 and 7.4.0 of @adonisjs/core.

CVE-2026-40170
Fecha de publicación:

Idioma:
Inglés
*** Pendiente de traducción *** ngtcp2 is a C implementation of the IETF QUIC protocol. In versions prior to 1.22.1, ngtcp2_qlog_parameters_set_transport_params() serializes peer transport parameters into a fixed 1024-byte stack buffer without bounds checking. When qlog is enabled, a remote peer can send sufficiently large transport parameters during the QUIC handshake to cause writes beyond the buffer boundary, resulting in a stack buffer overflow. This affects deployments that enable the qlog callback and process untrusted peer transport parameters. This issue has been fixed in version 1.22.1. If developers are unable to immediately upgrade, they can disable the qlog on client.

CVE-2026-40249
Fecha de publicación:

Idioma:
Inglés
*** Pendiente de traducción *** free5GC is an open-source implementation of the 5G core network. In versions 4.2.1 and below of the UDR service, the PUT handler for updating Policy Data notification subscriptions at /nudr-dr/v2/policy-data/subs-to-notify/{subsId} does not return after request body retrieval or deserialization errors. Although HTTP 500 or 400 error responses are sent, execution continues and the processor is invoked with a potentially uninitialized or partially initialized PolicyDataSubscription object. This fail-open behavior may allow unintended modification of existing Policy Data notification subscriptions with invalid or empty input, depending on downstream processor and storage behavior. A patched version was not available at the time of publication.

*** Pendiente de traducción *** free5GC is an open-source implementation of the 5G core network. In versions 4.2.1 and below of the UDR service, the handler for reading Traffic Influence Subscriptions checks whether the influenceId path segment equals subs-to-notify, but does not return after sending the HTTP 404 response when validation fails. Execution continues and the subscription data is returned alongside the 404 response. An unauthenticated attacker with access to the 5G Service Based Interface can read arbitrary Traffic Influence Subscriptions, including SUPIs/IMSIs, DNNs, S-NSSAIs, and callback URIs, by supplying any value for the influenceId path segment. A patched version was not available at the time of publication.

*** Pendiente de traducción *** free5GC is an open-source implementation of the 5G core network. In versions 1.4.2 and below of the UDR service, the handler for deleting Traffic Influence Subscriptions checks whether the influenceId path segment equals subs-to-notify, but does not return after sending the HTTP 404 response when validation fails. Execution continues and the subscription is deleted regardless. An unauthenticated attacker with access to the 5G Service Based Interface can delete arbitrary Traffic Influence Subscriptions by supplying any value for the influenceId path segment, while the API misleadingly returns a 404 Not Found response. A patched version was not available at the time of publication.
