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-2026-4893

Publication date:

11/05/2026

An information disclosure vulnerability in dnsmasq allows remote attackers to bypass source checks via a crafted DNS packet with RFC 7871 client subnet information.

Severity CVSS v4.0: Pending analysis

CVE-2026-5172

Publication date:

11/05/2026

A buffer overflow in dnsmasq’s extract_addresses() function allows an attacker to trigger a heap out-of-bounds read and crash by exploiting a malformed DNS response, enabling extract_name() to advance the pointer past the record’s end.

CVE-2026-45000

Publication date:

11/05/2026

OpenClaw before 2026.4.20 contains a server-side request forgery vulnerability in browser CDP profile creation that skips strict-mode SSRF policy checks. Attackers can create stored profiles pointing to private-network or metadata endpoints that bypass security policies and are later probed during normal profile status operations.

CVE-2026-45001

Publication date:

11/05/2026

OpenClaw before 2026.4.20 contains a guard bypass vulnerability in the agent-facing gateway config.patch and config.apply endpoints that fails to protect operator-trusted settings including sandbox policy, plugin enablement, gateway auth/TLS, hook routing, MCP server configuration, SSRF policy, and filesystem hardening. A prompt-injected model with access to the owner-only gateway tool can persist unauthorized changes to protected operator settings.

CVE-2026-45002

Publication date:

11/05/2026

OpenClaw before 2026.4.20 contains a hook session-key bypass vulnerability that allows attackers to circumvent the hooks.allowRequestSessionKey opt-in restriction. Attackers can render externally influenced session keys through templated hook mappings to bypass webhook routing isolation controls.

CVE-2026-45003

Publication date:

11/05/2026

OpenClaw before 2026.4.22 allows workspace dotenv files to override connector endpoint hosts for Matrix, Mattermost, IRC, and Synology connectors. Attackers with workspace access can redirect runtime traffic to malicious endpoints by setting endpoint variables in dotenv files.

CVE-2026-45004

Publication date:

11/05/2026

OpenClaw before 2026.4.23 contains an arbitrary code execution vulnerability in the bundled plugin setup resolver that loads setup-api.js from process.cwd() during provider setup metadata resolution. Attackers can execute arbitrary JavaScript under the current user account by placing a malicious extensions//setup-api.js file in a repository and convincing a user to run OpenClaw commands from that directory.

Severity CVSS v4.0: HIGH

CVE-2026-45005

Publication date:

11/05/2026

OpenClaw before 2026.4.23 caches resolved webhook route secrets backed by SecretRef values, allowing stale secrets to remain valid after rotation and reload. Attackers with previously valid webhook route secrets can continue authenticating requests and invoking configured webhook task flows until gateway or plugin restart.

Severity CVSS v4.0: MEDIUM

CVE-2026-45006

Publication date:

11/05/2026

OpenClaw before 2026.4.23 contains an improper access control vulnerability in the gateway tool&#39;s config.apply and config.patch operations that allows compromised models to write unsafe configuration changes by bypassing an incomplete denylist protection. Attackers can persist malicious config modifications affecting command execution, network behavior, credentials, and operator policies that survive restart.

Severity CVSS v4.0: HIGH

CVE-2026-44993

Publication date:

11/05/2026

OpenClaw before 2026.4.20 contains a message classification vulnerability in Feishu card-action callbacks that misclassifies direct messages as group conversations. Attackers can bypass dmPolicy enforcement by triggering card-action flows in direct message conversations that should have been blocked by restrictive policies.

Severity CVSS v4.0: LOW

CVE-2026-44994

Publication date:

11/05/2026

OpenClaw before 2026.4.22 contains an authentication bypass vulnerability in the Control UI bootstrap config endpoint that allows unauthenticated attackers to read sensitive configuration fields. Attackers can access the bootstrap config route without a valid Gateway token to expose sensitive bootstrap and config information intended only for authenticated Control UI sessions.

Severity CVSS v4.0: MEDIUM

CVE-2026-44995

Publication date:

11/05/2026

OpenClaw before 2026.4.20 contains an improper environment variable validation vulnerability in MCP stdio server configuration that allows attackers to execute arbitrary code. Malicious workspace configurations can pass dangerous startup variables like NODE_OPTIONS, LD_PRELOAD, or BASH_ENV to spawned MCP server processes, enabling code injection when operators start sessions using those servers.
