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-2026-72840

Publication date:

13/08/2026

OpenWrt LuCI contains an overly permissive ACL definition in luci-mod-system-mounts that grants write access to /etc/crontabs/root to users intended only for mount configuration. Authenticated users with only the mount-configuration ACL group can append arbitrary cron entries via ubus file.write, which the default busybox crond daemon executes as root within one minute.

CVE-2026-72776

Publication date:

13/08/2026

AgenticSeek (commit fc242c7) contains an unauthenticated remote code execution vulnerability that allows any network-adjacent attacker to execute arbitrary commands by submitting crafted queries to the unprotected POST /query API endpoint bound to 0.0.0.0:7777 with wildcard CORS. Attackers can send unauthenticated HTTP requests that cause the autonomous agent to generate and execute shell commands through BashInterpreter using subprocess.Popen with shell=True and safety=False, bypassing the incomplete command blocklist to achieve full host-level code execution.

CVE-2026-72841

Publication date:

13/08/2026

luci-app-openvpn fails to properly validate the instance_name2 parameter during file upload, allowing authenticated users to perform path traversal and write arbitrary files outside the intended directory. Attackers can upload malicious payloads to gain persistent root code execution by placing SSH keys in system directories accessible on reboot.

CVE-2026-56853

Publication date:

13/08/2026

When a server is configured to support unencrypted HTTP/2, it reads a few bytes from each new connection to see if they contain the HTTP/2 client preface. ReadHeaderTimeout is unexpectedly not being applied when doing this.

CVE-2026-56858

Publication date:

13/08/2026

Previously, pathological inputs could close an unescaped &#39;/&#39; early, allowing for attack-controlled data to inject arbitrary content, potentially leading to XSS.

CVE-2026-56859

Publication date:

13/08/2026

Previously, DecodeElement would reset the depth counter causing it to never fire; this could lead to stack exhaustion.

CVE-2026-56862

Publication date:

13/08/2026

Handshake messages, such as KeyUpdate, are always considered as state-advancing, regardless of whether a handshake has been completed or not. As a result, a malicious client can keep sending KeyUpdate messages to force the server to keep performing key derivation operations indefinitely.

CVE-2026-56865

Publication date:

13/08/2026

A malicious GOPROXY was previously capable of forging up to two sumdb tiles that allow for a requested module to bypass the GOSUMDB check and persist attacker-controlled module content to a local Go module cache. This attack allows for a malicious GOPROXY to serve malicious module content that cannot be detected by evaluating the transparency log. All tiles are now correctly verified against their parents. In order to determine if you have been affected: rm -r go.sum go.work.sum vendor/ && go mod tidy

CVE-2026-56860

Publication date:

13/08/2026

Previously, resolving relative paths containing parent directory (&#39;..&#39;) segments performed string conversions and buffer rewrites on each step, resulting in quadratic time complexity and high memory allocation overhead. Now, path resolution operates on a byte buffer using index-based backtracking for &#39;..&#39; segments, eliminating the quadratic time complexity and significantly reducing memory allocations.

CVE-2026-56864

Publication date:

13/08/2026

A malicious GOSUMDB was capable of serving arbitrary module content not contained within the transparency log. This attack allows for a coordinating GOPROXY and GOSUMDB to serve a client malicious module content that cannot be detected by evaluating the transparency log. In order to determine if you have been affected: rm -r go.sum go.work.sum vendor/ && go mod tidy

CVE-2026-19750

Publication date:

13/08/2026

A flaw has been found in Tenda CH, CP and TX3 V21.x/V22.x/V25.x/V26.x/V27.x. Affected by this issue is some unknown functionality of the component SSH. Executing a manipulation can lead to use of hard-coded password. It is possible to launch the attack remotely. The attack requires a high level of complexity. The exploitation is known to be difficult. The exploit has been published and may be used.
