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-2026-62206

Fecha de publicación:

Idioma:

*** Pendiente de traducción *** OpenClaw versions before 2026.6.9 contain a missing authorization vulnerability in Discord moderation actions. In affected versions, a lower-trust caller or configured input path could perform moderation actions that should have required a stronger authorization or policy check. Practical impact depends on the operator's configuration and whether lower-trust input can reach the affected path.

*** Pendiente de traducción *** OpenClaw versions before 2026.6.6 contain a network policy bypass vulnerability in the sandbox exec-server that allows lower-trust callers to reach internal network destinations blocked by OpenClaw policy. Attackers can send HTTP requests through the exec-server to access network resources that should have been restricted by configured policies.

Idioma:
Inglés
*** Pendiente de traducción *** OpenClaw versions 2026.6.1 before 2026.6.9 contain a privilege escalation vulnerability in isolated cron jobs that allows lower-trust callers to regain denied execution tools. Attackers can execute or persist actions beyond their intended authorization by leveraging misconfigured input paths in the affected cron feature.

CVE-2026-62205

Fecha de publicación:
17/07/2026
Idioma:
Inglés
*** Pendiente de traducción *** OpenClaw versions 2026.4.12-beta.1 before 2026.6.6 contain a missing-authorization vulnerability in the MS Teams message actions feature. When the affected feature is enabled and reachable, a lower-trust caller or a configured input path can perform actions that should have required a stronger authorization or policy check. Practical impact depends on the operator's configuration and whether lower-trust input can reach that path. The issue is fixed in 2026.6.6.

Idioma:
Inglés
*** Pendiente de traducción *** OpenClaw versions before 2026.6.6 contain an environment variable filtering vulnerability in host exec that fails to properly sanitize rustup startup variables. Attackers with lower-trust caller access or configured input paths can execute or persist actions beyond their intended authorization level.

CVE-2026-2594

Fecha de publicación:
17/07/2026
Idioma:
Inglés
*** Pendiente de traducción *** The Smart Custom Fields plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 5.0.7. This is due to insufficient input sanitization and output escaping of uploaded image attachment titles. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. NOTE: This vulnerability was partially patched in 5.0.7.

CVE-2026-44251

Fecha de publicación:
17/07/2026
Idioma:
Inglés
*** Pendiente de traducción *** Wazuh is a free and open source platform used for threat prevention, detection, and response. In versions 3.0.0 and above, prior to 4.14.5, a size_t integer underflow in os_crypto/shared/msgs.c:389 allows any enrolled Wazuh agent to crash the wazuh-remoted process on the manager, immediately disconnecting all agents from the manager. A second code path reached by the same underflow may allow heap memory corruption. This issue has been fixed in version 4.14.5.

CVE-2026-40106

Fecha de publicación:
17/07/2026
Idioma:
Inglés
*** Pendiente de traducción *** Wazuh is a free and open source platform used for threat prevention, detection, and response. Versions 4.6.0 and above prior to 4.14.5 contain a heap-based buffer overflow vulnerability in the syscheck component of the Wazuh agent for Windows. When expanding registry paths containing wildcards (* or ?), the agent allocates a fixed-size heap buffer of 256 bytes (OS_SIZE_256). By creating a registry subkey with a maximum allowed length (255 characters) inside a monitored path, a low-privileged local attacker can force an out-of-bounds write during string concatenation. Since wazuh-agent.exe runs as NT AUTHORITY\SYSTEM, this can lead to a silent Denial of Service (blinding the agent) or potentially Local Privilege Escalation (LPE). This issue has been fixed in version 4.14.5.

CVE-2026-14956

Fecha de publicación:
17/07/2026
Idioma:
Inglés
*** Pendiente de traducción *** The Bricksforge plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.1.8.6. This is due to improper validation of the fieldIds parameter in the Pro Forms registration action, which allows attacker-supplied field IDs to be added to the trusted form-field whitelist. This makes it possible for unauthenticated attackers to register a new administrator account by submitting a crafted request to a publicly accessible Bricksforge Pro Forms registration form. Successful exploitation requires that the site has a public Bricksforge Pro Forms element configured with the User Registration action.

CVE-2026-54340

Fecha de publicación:
17/07/2026
Idioma:
Inglés
*** Pendiente de traducción *** h2o is an HTTP server with support for HTTP/1.x, HTTP/2 and HTTP/3. Prior to commit 9265bdd, there is an HTTP/2 state amplification issue that combines HPACK decompression amplification with Slowloris-style stream stalling. Amplified decoded header state can be retained by stalled HTTP/2 streams, and depending on the configuration, additional limits are needed to bound decoded header state and prevent attack. This issue has been fixed by commit 9265bdd.

CVE-2026-33754

Fecha de publicación:
17/07/2026
Idioma:
Inglés
*** Pendiente de traducción *** Wazuh is a free and open source platform used for threat prevention, detection, and response. In versions 3.9.0 and above, prior to 4.14.5, a remote attacker can trigger memory exhaustion in the cluster protocol parser by sending a crafted message header with an arbitrarily large payload length. The length is trusted before authentication/decryption and used directly to allocate memory, allowing unauthenticated denial of service of the cluster service. This issue has been fixed in version 4.14.5.

CVE-2026-34150

Fecha de publicación:
17/07/2026
Idioma:
Inglés
*** Pendiente de traducción *** Wazuh is a free and open source platform used for threat prevention, detection, and response. In versions 1.0.0 and above, prior to 4.14.5, a heap buffer overflow in wazuh-analysisd allows an unauthenticated remote attacker to crash the Wazuh manager's analysis engine, causing complete loss of SIEM alert processing. The attack exploits the default configuration shipped in the official wazuh/wazuh-docker deployment with default configuration. An attacker can enroll with authd without a password to obtain a valid agent ID and encryption key, connect to remoted over the Wazuh agent protocol, and inject rootcheck events containing  {key: value}  patterns longer than 30 bytes that trigger a sprintf overflow of a 30-byte buffer in W_JSON_ParseRootcheck, corrupting the heap and crashing wazuh-analysisd so that all alert processing silently stops while the dashboard and API keep showing stale data.
