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 *** Incomplete path traversal fixes in awslabs/tough before tough-v0.22.0 allow remote authenticated users with delegated signing authority to write files outside intended output directories via absolute target names in copy_target/link_target, symlinked parent directories in save_target, or symlinked metadata filenames in SignedRole::write, because write paths trust the joined destination path without post-resolution containment verification. We recommend you upgrade to tough-v0.22.0 / tuftool-v0.15.0.

*** Pendiente de traducción *** BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to 1.4.3, an out-of-bounds read vulnerability in bacnet-stack&#39;s ReadPropertyMultiple service property decoder allows unauthenticated remote attackers to read past allocated buffer boundaries by sending an RPM request with a truncated property list. The vulnerability stems from rpm_decode_object_property() calling the deprecated decode_tag_number_and_value() function at src/bacnet/rpm.c:344, which accepts no buffer length parameter and reads blindly from whatever pointer it receives. A crafted BACnet/IP packet with a 1-byte property payload containing an extended tag marker (0xF9) causes the decoder to read 1 byte past the end of the buffer, leading to crashes on embedded BACnet devices. The vulnerability exists in src/bacnet/rpm.c and affects any deployment that enables the ReadPropertyMultiple confirmed service handler (enabled by default in the reference server). This vulnerability is fixed in 1.4.3.

*** Pendiente de traducción *** BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to 1.4.3, an off-by-one out-of-bounds read vulnerability in bacnet-stack&#39;s ReadPropertyMultiple service decoder allows unauthenticated remote attackers to read one byte past an allocated buffer boundary by sending a crafted RPM request with a truncated object identifier. The vulnerability is in rpm_decode_object_id(), which checks apdu_len

*** Pendiente de traducción *** BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to 1.4.3, an out-of-bounds read vulnerability in bacnet-stack&#39;s WritePropertyMultiple service decoder allows unauthenticated remote attackers to read past allocated buffer boundaries by sending a truncated WPM request. The vulnerability stems from wpm_decode_object_property() calling the deprecated decode_tag_number_and_value() function, which performs no bounds checking on the input buffer. A crafted BACnet/IP packet with a truncated property payload causes the decoder to read 1-7 bytes past the end of the buffer, leading to crashes or information disclosure on embedded BACnet devices. This vulnerability is fixed in 1.4.3.

*** Pendiente de traducción *** Deskflow is a keyboard and mouse sharing app. In 1.20.0, 1.26.0.134, and earlier, Deskflow daemon runs as SYSTEM and exposes an IPC named pipe with WorldAccessOption enabled. The daemon processes privileged commands without authentication, allowing any local unprivileged user to execute arbitrary commands as SYSTEM. Affects both stable v1.20.0 + and Continuous v1.26.0.134 prerelease.

*** Pendiente de traducción *** Deskflow is a keyboard and mouse sharing app. Prior to 1.26.0.138, a remote memory-safety vulnerability in Deskflow&#39;s clipboard deserialization allows a connected peer to trigger an out-of-bounds read by sending a malformed clipboard update. The issue is in the implementation of src/lib/deskflow/IClipboard.cpp. This is reachable because ClipboardChunk::assemble() in src/lib/deskflow/ClipboardChunk.cpp validates only the outer clipboard transfer size. It does not validate the internal structure of the serialized clipboard blob, so malformed inner lengths reach IClipboard::unmarshall() unchanged. This vulnerability is fixed in 1.26.0.138.

*** Pendiente de traducción *** Improper verification of cryptographic signature uniqueness in delegated role validation in awslabs/tough before tough-v0.22.0 allows remote authenticated users to bypass the TUF signature threshold requirement by duplicating a valid signature, causing the client to accept forged delegated role metadata. We recommend you upgrade to tough-v0.22.0 / tuftool-v0.15.0.

CVE-2026-41428

Fecha de publicación:

24/04/2026

Idioma:

Inglés

*** Pendiente de traducción *** Budibase is an open-source low-code platform. Prior to 3.35.4, the authenticated middleware uses unanchored regular expressions to match public (no-auth) endpoint patterns against ctx.request.url. Since ctx.request.url in Koa includes the query string, an attacker can access any protected endpoint by appending a public endpoint path as a query parameter. For example, POST /api/global/users/search?x=/api/system/status bypasses all authentication because the regex /api/system/status/ matches in the query string portion of the URL. This vulnerability is fixed in 3.35.4.

*** Pendiente de traducción *** pretalx is a conference planning tool. Prior to 2026.1.0, an unauthenticated attacker can send arbitrary HTML-rendered emails from a pretalx instance&#39;s configured sender address by embedding malformed HTML or markdown link syntax in a user-controlled template placeholder such as the account display name. The most direct vector is the password-reset flow: the attacker registers an account with a malicious name, enters the victim&#39;s email address, and triggers a password reset. The resulting email is delivered from the event&#39;s legitimate sender address and passes SPF/DKIM/DMARC validation, making it a ready-made phishing vector. This vulnerability is fixed in 2026.1.0.

*** Pendiente de traducción *** arduino-esp32 is an Arduino core for the ESP32, ESP32-S2, ESP32-S3, ESP32-C3, ESP32-C6 and ESP32-H2 microcontrollers. Prior to 3.3.8, there is a remotely reachable memory corruption issue in the NBNS packet handling path. When NetBIOS is enabled by calling NBNS.begin(...), the device listens on UDP port 137 and processes untrusted NBNS requests from the local network. The request parser trusts the attacker-controlled name_len field without enforcing a bound consistent with the fixed-size destination buffers used later in the flow. This vulnerability is fixed in 3.3.8.

*** Pendiente de traducción *** Better Auth is an authentication and authorization library for TypeScript. Prior to 1.6.5, the clientPrivileges option documents a create action, but the OAuth client creation endpoints did not invoke the hook before persisting new clients. Deployments that configured clientPrivileges to restrict client registration were not actually restricted — any authenticated user could reach the create endpoints and register an OAuth client with attacker-chosen redirect URIs and metadata. This vulnerability is fixed in 1.6.5.
