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, a member-level user with editor access to a shared workflow could reference credentials they do not own via specific public API endpoints. Credential ownership checks were only enforced partially leading to cross-user credential access. This issue affects instances where workflow sharing is enabled and at least one workflow has been shared with a member-level user as an Editor. This vulnerability is fixed in 1.123.55, 2.25.7, and 2.26.2.

CVE-2026-54307 is an authorization bypass vulnerability in the n8n workflow automation platform. Specifically, member-level users granted editor access to shared workflows could exploit incomplete credential ownership verification in public API endpoints to access credentials owned by other users. This issue arises only when workflow sharing is enabled and at least one workflow is shared with an editor-level member. The vulnerability affects versions prior to 1.123.55, 2.25.7, and 2.26.2, where it has been fixed.
