CVE-2026-42235: CWE-87: Improper Neutralization of Alternate XSS Syntax in n8n-io n8nCVE-2026-42235 0 CVE-2026-42235 is a high-severity vulnerability in the n8n workflow automation platform affecting versions prior to 1.123.32, 2.17.4, and 2.18.1. It allows an unauthenticated attacker to register a malicious OAuth client with a crafted client_name that leads to improper neutralization of alternate XSS syntax. When a victim user authorizes the OAuth consent and another user revokes access, a toast notification renders injected script, enabling execution of arbitrary JavaScript in the victim's authenticated session. This can result in credential and session token theft, workflow manipulation, or privilege escalation.
