Vulnerabilities

With the aim of informing, warning and helping professionals with the latest security vulnerabilities in technology systems, we have made a database available for users interested in this information, which is in Spanish and includes all of the latest documented and recognised vulnerabilities.

This repository, with over 75,000 registers, is based on the information from the NVD (National Vulnerability Database) – by virtue of a partnership agreement – through which INCIBE translates the included information into Spanish.

On occasions this list will show vulnerabilities that have still not been translated, as they are added while the INCIBE team is still carrying out the translation process. The CVE (Common Vulnerabilities and Exposures) Standard for Information Security Vulnerability Names is used with the aim to support the exchange of information between different tools and databases.

All vulnerabilities collected are linked to different information sources, as well as available patches or solutions provided by manufacturers and developers. It is possible to carry out advanced searches, as there is the option to select different criteria to narrow down the results, some examples being vulnerability types, manufacturers and impact levels, among others.

Through RSS feeds or Newsletters we can be informed daily about the latest vulnerabilities added to the repository. Below there is a list, updated daily, where you can discover the latest vulnerabilities.

CVE-2026-20301

Publication date:

05/08/2026

A vulnerability in the Extensible Messaging Client Protocol (XMCP), also referred to as the External Client protocol, of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper handling of malformed XMCP packets. An attacker could exploit this vulnerability by sending a malformed XMCP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to reload unexpectedly, resulting in a DoS condition. The attacker does not need the XMCP client username to exploit this vulnerability.

CVE-2026-20288

Publication date:

05/08/2026

A vulnerability in the web-based management interface of Cisco IMC could allow an authenticated, remote attacker with&nbsp;Admin privileges to execute arbitrary commands on the underlying operating system of an affected system and elevate privileges to root.&nbsp; This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by entering crafted inputs to the web-based management interface of the affected software. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system as the root user.&nbsp; Cisco has assigned this vulnerability a SIR of High rather than Medium as the score indicates because additional security implications could occur when the attacker becomes&nbsp;root.

CVE-2026-20289

Publication date:

05/08/2026

A vulnerability in the logging subsystem of Cisco RoomOS could allow an authenticated, local attacker with low privileges to access sensitive information. This vulnerability is due to the logging of sensitive information. An attacker could exploit this vulnerability by enabling a specific logging level and then collecting the system logs. A successful exploit could allow the attacker to view sensitive information like user login credentials.

CVE-2026-20294

Publication date:

05/08/2026

A vulnerability in the web-based management interface of Cisco Catalyst SD-WAN Manager could allow an authenticated, remote attacker to view sensitive information in clear text on an affected system. This vulnerability is due to insufficient access control enforcement for specific template types that are not included in the encryption allowlist. A low-privileged attacker could exploit this vulnerability by viewing logs on the local system or on a remote logging server. A successful exploit could allow the attacker to view sensitive authentication credentials, which could lead to further compromise of network infrastructure and connected services.
