SCA: security update for n8n (GHSA-hfmv-hhh3-43f2)

medium Tenable Cloud Security Plugin ID 434058

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- n8n is a workflow automation platform. From 1.77.0 to before 1.98.2, a stored Cross-Site Scripting (XSS)
vulnerability was identified in n8n, specifically in the Form Trigger node's HTML form element. An
authenticated attacker can inject malicious HTML via an <iframe> with a srcdoc payload that includes
arbitrary JavaScript execution. The attacker can also inject malicious Javascript by using <video> coupled
<source> using an onerror event. While using iframe or a combination of video and source tag, this
vulnerability allows for Account Takeover (ATO) by exfiltrating n8n-browserId and session cookies from
authenticated users who visit a maliciously crafted form. Using these tokens and cookies, an attacker can
impersonate the victim and change account details such as email addresses, enabling full control over the
account—especially if 2FA is not enabled. Users should upgrade to version >= 1.98.2. (CVE-2025-52478)
