n8n: Denial of Service via ZIP decompression in webhook workflow

Impact The Compression node's Decompress operation expanded attacker-controlled archives into memory without enforcing limits on decompressed output size. An unauthenticated attacker could send a small compressed archive to a public webhook workflow using this node, causing the n8n process to...

GHSA-JWM3-QCFW-C5PP n8n: Python Code Node AST Validator Bypass

Impact An authenticated user with permission to create or modify workflows containing a Python Code node could bypass the AST security validator and access the task executor module namespace. On self-hosted instances where N8NBLOCKRUNNERENVACCESS=false is set, this extended to disclosure of...

n8n: Stored XSS in Chat Trigger Node

Impact 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. Patches T...

n8n: Reflected XSS via Facebook, WhatsApp, and Microsoft Teams Trigger Webhook Verification Endpoints

Impact An endpoint in the Meta and Microsoft Teams trigger nodes reflects a query parameter into the HTTP response without sanitization or Content-Security-Policy headers, enabling reflected XSS in the n8n origin when a logged-in user visits a crafted URL. Patches The issue has been fixed in n8n...
