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 2.25.7 and 2.26.2, the MicrosoftAgent365Trigger and StripeTrigger node did not validate that inbound requests. As a result, an unauthenticated attacker who knows the webhook URL could submit a forged payload and cause the workflow to execute with attacker-controlled data. This vulnerability is fixed in 2.25.7 and 2.26.2.

CVE-2026-54308 is an authentication bypass vulnerability (CWE-290) in the n8n open source workflow automation platform. Specifically, in versions before 2.25.7 and 2.26.2, the MicrosoftAgent365Trigger and StripeTrigger nodes did not validate inbound requests properly. This allowed unauthenticated attackers who know the webhook URL to send forged payloads, triggering workflows with attacker-controlled data. The vulnerability has a CVSS 4.0 score of 6.3 (medium severity) and is fixed in versions 2.25.7 and 2.26.2.
