Stored cross-site scripting in n8n's markdown rendering component allows authenticated users to inject malicious scripts into workflows and sticky notes that execute with session privileges when viewed by other users. An attacker with workflow modification permissions can exploit this to hijack sessions and compromise accounts of users who interact with affected workflows. Versions 1.123.9 and 2.2.1 contain fixes for this vulnerability.

n8n has a command injection vulnerability (CVSS 9.9) allowing authenticated users to execute arbitrary OS commands through workflow definitions.

n8n has a TOCTOU race condition vulnerability (CVSS 9.9) enabling bypass of execution restrictions in workflow processing.

Improper Content Security Policy enforcement in n8n workflow automation allows authenticated users to inject persistent XSS payloads into webhook responses that execute with same-origin privileges when other users access the affected workflows. An attacker with workflow creation/modification permissions could exploit this to hijack sessions and compromise user accounts. The vulnerability affects n8n versions prior to 1.123.2.

n8n workflow automation platform has an authenticated code execution vulnerability (CVSS 9.9) through improper runtime behavior modification, enabling server takeover.

n8n is an open source workflow automation platform. From version 1.65.0 to before 1.114.3, the use of Buffer.allocUnsafe() and Buffer.allocUnsafeSlow() in the task runner allowed untrusted code to allocate uninitialized memory. [CVSS 7.7 HIGH]

n8n has a fifth critical RCE vulnerability (CVSS 9.9) in the Expression evaluator, enabling code execution through crafted workflow expressions.

Authenticated users can exploit string formatting and exception handling in n8n's Python task executor to escape sandbox restrictions and execute arbitrary code on the underlying operating system, with full instance takeover possible in Internal execution mode. Public exploit code exists for this vulnerability, which affects n8n deployments running under Internal execution mode where the Python executor has direct OS access. External execution mode deployments using Docker sidecars have reduced impact as code execution is confined to the container rather than the main node.

n8n is an open source workflow automation platform. From 1.36.0 to before 2.2.0, the Webhook node’s IP whitelist validation performed partial string matching instead of exact IP comparison. [CVSS 5.3 MEDIUM]

n8n versions 0.150.0 through 2.2.1 lack webhook signature verification in the Stripe Trigger node, enabling unauthenticated attackers to forge Stripe events and trigger workflows by sending crafted POST requests to known webhook URLs. Affected users with active Stripe Trigger workflows could experience unauthorized execution of automation logic, potentially allowing attackers to simulate fraudulent payment or subscription events. A patch is available in version 2.2.2 and later.

n8n workflow automation (through 1.121.2) allows authenticated users to execute arbitrary code via the n8n service, with scope change enabling full compromise of both self-hosted and cloud instances. EPSS 12.5% indicates high exploitation activity. Patch available.

n8n workflow automation (1.65.0 to 1.121.0) allows unauthenticated file access through form-based workflows. A critical CVSS 10.0 vulnerability enabling remote attackers to read sensitive files from the server, with potential for further compromise. PoC available.

n8n is a workflow automation platform. Rated high severity (CVSS 8.7), this vulnerability is remotely exploitable, low attack complexity. This Cross-Site Scripting (XSS) vulnerability could allow attackers to inject malicious scripts into web pages viewed by other users.

n8n is a workflow automation platform. Prior to version 1.99.1, an authorization vulnerability was discovered in the /rest/executions/:id/stop endpoint of n8n. An authenticated user can stop workflow executions that they do not own or that have not been shared with them, leading to potential business disruption. This issue has been patched in version 1.99.1. A workaround involves restricting access to the /rest/executions/:id/stop endpoint via reverse proxy or API gateway.

n8n is a workflow automation platform. Prior to version 1.99.0, there is a denial of Service vulnerability in /rest/binary-data endpoint when processing empty filesystem URIs (filesystem:// or filesystem-v2://). This allows authenticated attackers to cause service unavailability through malformed filesystem URI requests, effecting the /rest/binary-data endpoint and n8n.cloud instances (confirmed HTTP/2 524 timeout responses). Attackers can exploit this by sending GET requests with empty filesystem URIs (filesystem:// or filesystem-v2://) to the /rest/binary-data endpoint, causing resource exhaustion and service disruption. This issue has been patched in version 1.99.0.

n8n is a workflow automation platform. Versions prior to 1.98.0 have an Open Redirect vulnerability in the login flow. Authenticated users can be redirected to untrusted, attacker-controlled domains after logging in, by crafting malicious URLs with a misleading redirect query parameter. This may lead to phishing attacks by impersonating the n8n UI on lookalike domains (e.g., n8n.local.evil.com), credential or 2FA theft if users are tricked into re-entering sensitive information, and/or reputation risk due to the visual similarity between attacker-controlled domains and trusted ones. The vulnerability affects anyone hosting n8n and exposing the `/signin` endpoint to users. The issue has been patched in version 1.98.0. All users should upgrade to this version or later. The fix introduces strict origin validation for redirect URLs, ensuring only same-origin or relative paths are allowed after login.

n8n is a workflow automation platform. Rated medium severity (CVSS 5.0). This Cross-Site Scripting (XSS) vulnerability could allow attackers to inject malicious scripts into web pages viewed by other users.
