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.

*** Pendiente de traducción *** A flaw has been found in AstrBotDevs AstrBot up to 4.25.5. This vulnerability affects the function OpenApiRoute.get_chat_sessions of the file astrbot/dashboard/routes/open_api.py of the component session-listing Endpoint. This manipulation of the argument Username causes authorization bypass. It is possible to initiate the attack remotely. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

CVE-2026-56740
Fecha de publicación:

Idioma:
Inglés
*** Pendiente de traducción *** JLine is a Java library for handling console input. Prior to 3.30.14, 4.0.16, and 4.2.1, the JLine3 Telnet server remote-telnet module does not limit the number of environment variables a client may inject via the Telnet NEW-ENVIRON option, and TelnetIO.readNEVariables() in TelnetIO.java:1127-1180 stores each variable pair in a HashMap held by ConnectionData, allowing an unauthenticated attacker to flood unique variable pairs before the terminating IAC SE byte and exhaust JVM heap memory with an OutOfMemoryError. This issue is fixed in versions 3.30.14, 4.0.16, and 4.2.1.

*** Pendiente de traducción *** JLine is a Java library for handling console input. Prior to 3.30.14, 4.0.16, and 4.2.1, the JLine3 Telnet server remote-telnet module does not apply an upper bound to terminal dimensions received via the Telnet NAWS option, and TelnetIO.handleNAWS() in TelnetIO.java:856-879 reads client-supplied width and height as 16-bit unsigned integers and passes values such as 65535x65535 to setTerminalGeometry(), allowing an unauthenticated remote attacker to repeatedly alternate values and trigger continuous expensive rendering work that causes CPU exhaustion and denial of service. This issue is fixed in versions 3.30.14, 4.0.16, and 4.2.1.

CVE-2026-54335
Fecha de publicación:
17/07/2026
Idioma:
Inglés
*** Pendiente de traducción *** Feathersjs is a framework for creating web APIs and real-time applications with TypeScript or JavaScript. In 5.0.44 and earlier, the _.merge(target, source) utility exported by @feathersjs/commons recursively merges source into target by iterating Object.keys(source). When source was produced by JSON.parse and contains a __proto__, constructor, or prototype key, that key is returned as an own-enumerable property; the recursive merge then resolves target['__proto__'] to Object.prototype and writes attacker-supplied properties onto it, polluting the prototype for all plain objects in the process for the lifetime of the Node process. This issue is fixed in version 5.0.45.

CVE-2026-49485
Fecha de publicación:
17/07/2026
Idioma:
Inglés
*** Pendiente de traducción *** HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.9 and 6.9.4.2, all implementations of FHIRPathEngine accept arbitrary FHIRPath expressions and evaluate them without input validation, and the FHIRPath functions matches(), matchesFull(), and replaceMatches() pass user-controlled regular expressions to Java's Pattern.compile() and String.replaceAll() through an incomplete timeout utility. An attacker can send a resource containing an evil regex pattern that causes catastrophic backtracking, exhausting CPU resources and causing denial of service in the FHIR Validator HTTP endpoint and affected org.hl7.fhir.* modules. This issue is fixed in versions 6.9.9 and 6.9.4.2.

CVE-2026-48022
Fecha de publicación:
17/07/2026
Idioma:
Inglés
*** Pendiente de traducción *** @hapi/wreck is an HTTP client utility. Prior to 18.1.2, Wreck strips credential headers including Authorization, Cookie, and Proxy-Authorization before following a cross-origin redirect, but the origin check compares hostnames only and ignores scheme and port, so credentials are forwarded intact across same-host port changes and HTTPS-to-HTTP downgrades, allowing a co-tenant on an adjacent port or a network-position attacker capable of forging a redirect to capture bearer tokens, session cookies, and proxy credentials and impersonate the victim against the upstream service. This issue is fixed in version 18.1.2.

CVE-2026-48049
Fecha de publicación:
17/07/2026
Idioma:
Inglés
*** Pendiente de traducción *** @hapi/inert provides static file and directory handlers for hapi.js. From 4.0.0 to 7.1.0, @hapi/inert serves static files from a directory configured with path in the directory or file handlers or relativeTo for h.file(), with confinement enforced by the confine option, but the confinement check compared the resolved absolute path against the confine directory using a raw string-prefix test, so a sibling directory such as /app/static-secret next to /app/static was incorrectly accepted and could allow an unauthenticated remote attacker to read files via /..%2fstatic-secret/secret.txt. This issue is fixed in version 7.1.1.

CVE-2026-44979
Fecha de publicación:
17/07/2026
Idioma:
Inglés
*** Pendiente de traducción *** @hapi/wreck is an HTTP client utility. Prior to 18.1.1, when @hapi/wreck follows a 3xx redirect to a different hostname, only the Authorization and Cookie headers are stripped, and the standard credential header Proxy-Authorization is forwarded intact to the redirect target, potentially exposing forward-proxy credentials to a host outside the original trust boundary when redirects are enabled through the redirects option or Wreck.defaults({ redirects: ... }). This issue is fixed in version 18.1.1.

CVE-2026-55518
Fecha de publicación:
17/07/2026
Idioma:
Inglés
*** Pendiente de traducción *** Avo is a framework to create admin panels for Ruby on Rails apps. Prior to 3.32.1 and 4.0.0.beta.51, Avo's association attach workflow checks attach_? in the UI and GET /resources/:resource/:id/:related/new path, but the actual write endpoint, POST /resources/:resource/:id/:related, does not run the same authorization check before mutating the association through Avo::AssociationsController#create. An authenticated low-privileged Avo user can bypass hidden or disabled attach controls and directly attach related records to a parent record by sending a crafted POST request, which can lead to privilege escalation and cross-tenant data exposure where associations represent authorization-bearing relationships. This issue is fixed in versions 3.32.1 and 4.0.0.beta.51.

CVE-2026-54498
Fecha de publicación:
17/07/2026
Idioma:
Inglés
*** Pendiente de traducción *** view_component is a framework for building reusable, testable, and encapsulated view components in Ruby on Rails. From 4.0.0 until 4.12.0, ViewComponent::Base#around_render can return HTML-unsafe strings that bypass the escaping behavior applied to normal #call return values. This creates an XSS risk when downstream applications use around_render to wrap, replace, instrument, or conditionally return content that includes user-controlled data, and ViewComponent::Collection#render_in can amplify the issue by joining per-item results and marking the entire output html_safe, converting raw unsafe output into an ActiveSupport::SafeBuffer. This issue is fixed in version 4.12.0.
