AlienVault OTX Vulnerabilities

AlienVault OTX Malware

n8n heeft meerdere kwetsbaarheden verholpen in het n8n workflow automation platform, specifiek in versies voor 1.123.55, 2.24.0, 2.25.7, 2.26.1 en 2.26.2.

CVE-2026-54301 is a CWE-79 cross-site scripting vulnerability in the n8n workflow automation platform. It affects versions prior to 1.123.55, 2.25.7, and 2.26.2. The issue arises because an authenticated user with workflow edit permissions can configure a Respond to Webhook node to serve binary content with a malicious Content-Type header. This binary response path bypasses the central Content-Security-Policy sandbox header, enabling execution of attacker-controlled JavaScript in the context of the n8n origin when visited by an authenticated user. This can lead to session exposure or other impacts tied to script execution within the user's session context. The vulnerability has a CVSS v4.0 score of 7.0 (high severity) and requires user interaction and low privileges to exploit.

Kwetsbaarheden verholpen in n8n workflow automation platform

n8n is an open source workflow automation platform. Prior to 1.123.55, 2.25.7, and 2.26.2, an authenticated user with workflow edit access could inject arbitrary JavaScript into the Chat Trigger's generated page by setting a malicious webhookId. When a logged-in user visited the chat URL, the injected code executed in the n8n origin with that user's session privileges. This vulnerability is fixed in 1.123.55, 2.25.7, and 2.26.2.

CVE-2026-54302 is a CWE-79 cross-site scripting vulnerability in the n8n workflow automation platform. It affects versions prior to 1.123.55, 2.25.7, and 2.26.2. An authenticated user with workflow edit permissions can inject malicious JavaScript by setting a crafted webhookId in the Chat Trigger. When another authenticated user visits the chat URL, the injected script executes in the context of the n8n origin with that user's session privileges, potentially leading to session hijacking or other client-side attacks. The vulnerability is resolved in the specified fixed versions.
