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-2026-35633

Publication date:

09/04/2026

OpenClaw before 2026.3.22 contains an unbounded memory allocation vulnerability in remote media HTTP error handling that allows attackers to trigger excessive memory consumption. Attackers can send crafted HTTP error responses with large bodies to remote media endpoints, causing the application to allocate unbounded memory before failure handling occurs.

Severity CVSS v4.0: MEDIUM

CVE-2026-35632

Publication date:

09/04/2026

OpenClaw through 2026.2.22 contains a symlink traversal vulnerability in agents.create and agents.update handlers that use fs.appendFile on IDENTITY.md without symlink containment checks. Attackers with workspace access can plant symlinks to append attacker-controlled content to arbitrary files, enabling remote code execution via crontab injection or unauthorized access via SSH key manipulation.

CVE-2026-35636

Publication date:

09/04/2026

OpenClaw versions 2026.3.11 through 2026.3.24 contain a session isolation bypass vulnerability where session_status resolves sessionId to canonical session keys before enforcing visibility checks. Sandboxed child sessions can exploit this to access parent or sibling sessions that should be blocked by explicit sessionKey restrictions.

Severity CVSS v4.0: HIGH

CVE-2026-35634

Publication date:

09/04/2026

OpenClaw before 2026.3.23 contains an authentication bypass vulnerability in the Canvas gateway where authorizeCanvasRequest() unconditionally allows local-direct requests without validating bearer tokens or canvas capabilities. Attackers can send unauthenticated loopback HTTP and WebSocket requests to Canvas routes to bypass authentication and gain unauthorized access.

CVE-2026-35628

Publication date:

09/04/2026

OpenClaw before 2026.3.25 contains a missing rate limiting vulnerability in Telegram webhook authentication that allows attackers to brute-force weak webhook secrets. The vulnerability enables repeated authentication guesses without throttling, permitting attackers to systematically guess webhook secrets through brute-force attacks.

Severity CVSS v4.0: MEDIUM

CVE-2026-35631

Publication date:

09/04/2026

OpenClaw before 2026.3.22 fails to enforce operator.admin scope on mutating internal ACP chat commands, allowing unauthorized modifications. Attackers without admin privileges can execute mutating control-plane actions by directly invoking affected ACP commands to bypass authorization gates.

Severity CVSS v4.0: HIGH

CVE-2026-35626

Publication date:

09/04/2026

OpenClaw before 2026.3.22 contains an unauthenticated resource exhaustion vulnerability in voice call webhook handling that buffers request bodies before provider signature checks. Attackers can send large or malicious webhook requests to exhaust server resources without authentication by bypassing signature validation.

Severity CVSS v4.0: MEDIUM

CVE-2026-35629

Publication date:

09/04/2026

OpenClaw before 2026.3.25 contains a server-side request forgery vulnerability in multiple channel extensions that fail to properly guard configured base URLs against SSRF attacks. Attackers can exploit unprotected fetch() calls against configured endpoints to rebind requests to blocked internal destinations and access restricted resources.

Severity CVSS v4.0: MEDIUM

CVE-2026-35627

Publication date:

09/04/2026

OpenClaw before 2026.3.22 performs cryptographic and dispatch operations on inbound Nostr direct messages before enforcing sender and pairing policy validation. Attackers can trigger unauthorized pre-authentication computation by sending crafted DM messages, enabling denial of service through resource exhaustion.

Severity CVSS v4.0: MEDIUM

CVE-2026-35625

Publication date:

09/04/2026

OpenClaw before 2026.3.25 contains a privilege escalation vulnerability where silent local shared-auth reconnects auto-approve scope-upgrade requests, widening paired device permissions from operator.read to operator.admin. Attackers can exploit this by triggering local reconnection to silently escalate privileges and achieve remote code execution on the node.

Severity CVSS v4.0: HIGH

CVE-2026-35623

Publication date:

09/04/2026

OpenClaw before 2026.3.25 contains a missing rate limiting vulnerability in webhook authentication that allows attackers to brute-force weak webhook passwords without throttling. Remote attackers can repeatedly submit incorrect password guesses to the webhook endpoint to compromise authentication and gain unauthorized access.

Severity CVSS v4.0: MEDIUM

CVE-2026-35624

Publication date:

09/04/2026

OpenClaw before 2026.3.22 contains a policy confusion vulnerability in room authorization that matches colliding room names instead of stable room tokens. Attackers can exploit similarly named rooms to bypass allowlist policies and gain unauthorized access to protected Nextcloud Talk rooms.

Severity CVSS v4.0: LOW
