GHSA-GQ66-9CW5-J5JM n8n: GraphQL Node Bypasses "Allowed HTTP Request Domains" Restriction

Impact The GraphQL node did not enforce the "Allowed HTTP Request Domains" restriction on HTTP-based credentials such as Header Auth, Basic Auth, Query Auth, and OAuth, unlike the HTTP Request node. An authenticated user able to create or edit workflows could therefore point the node's endpoint a...

n8n: Member-Level Users Can Execute Other Users' MCP Server Trigger Workflows via Missing OAuth Authorization Check

Impact The OAuth 2.1 consent and token-issuance flow introduced in n8n 2.27.0 does not verify that the authenticated user has access to the workflow referenced as the OAuth resource. A member-level user can register an OAuth client, self-approve consent for another user's n8n OAuth2-protected MCP...

GHSA-W867-JM58-P9PV n8n: Authenticated Users Can Exhaust Temporary Disk Storage via Data-Table File Uploads

Impact An authenticated user can repeatedly upload files to the data-table upload endpoint, bypassing the per-request quota check, which does not account for files already written to the shared temporary directory. This causes temporary files to accumulate on disk until the periodic cleanup runs,...

GHSA-PF2Q-PXHF-HGMW n8n: Path-Confinement Bypass in computer-use search_files Allows Reading Files Outside the Base Directory

Impact The component @n8n/computer-use file-search tool confined searches to a configured base directory. A crafted search pattern could bypass the confinement check and expand to locations outside that directory, causing the tool to return the names and contents of files anywhere the daemon's OS...

GHSA-HX4H-VR3M-45VH n8n: Prototype Pollution via VM Expression Engine Sandbox Escape Leads to Denial of Service

Impact An authenticated user able to create or edit a workflow expression could abuse the expression engine's array-element access to obtain a reference to a host built-in and pollute its prototype in the main n8n process, leading to a denial of service. Both self-hosted and cloud instances runni...

GHSA-GV7G-JM28-CR3M n8n: Expression sandbox escape via arrow-function bodies enabling command execution

Impact An authenticated user with permission to create or modify workflows could abuse crafted expressions using arrow functions to bypass the expression sandbox, triggering unintended system command execution on the host running n8n. Patches The issue has been fixed in n8n versions 2.31.5 and...

GHSA-RCV6-PVRJ-4XCG n8n: Authenticated code execution in the n8n Git node

Impact Authenticated n8n users with rights to create and execute workflows could achieve code execution on the n8n host. Using the Git node, under the default git security settings, by staging a crafted local repository, an attacker could cause git to run hooks, executing arbitrary commands as th...

GHSA-8342-988Q-86CR n8n: Account Takeover via Unverified Email Claim in Token Exchange Embed Login

Impact In an n8n instance, when a validly-signed incoming token was matched to a local account by its email claim, the service did not check that the trusted key's permitted role ceiling covered that account, nor that the email claim was verified. As a result, anyone able to obtain a token accept...

GHSA-35Q8-9MJ6-WJMF n8n: SSO Instance-Role Provisioning Allows Privilege Escalation to Instance Owner

Impact n8n's Enterprise SSO instance-role provisioning maps a role claim asserted by the configured Identity Provider IdP to an n8n global role and applies it during authentication. The provisioning path did not prevent assignment of the global:owner role, unlike the token-exchange identity path,...

GHSA-MQ3M-F8X3-579W n8n: Cross-Issuer Token Exchange Account Binding via Subject-Only Identity Resolution

Impact When an n8n instance is configured with more than one trusted token-exchange issuer, external identities are resolved to local accounts using only the JWT sub claim, ignoring the issuer iss. As a result, two different issuers that emit the same subject value map to the same local account. ...

n8n: Shared Credential Header Leak via HTTP Request Pagination Expression

Impact An authenticated member with use-only editor access to a shared workflow could read credential-populated headers exposed via the $request object inside an HTTP Request node's pagination expression. When an HTTP Header Auth credential is applied to a paginated request, the secret is present...

GHSA-9R8P-H6CC-6QHM n8n: Google Service Account Private Key Exposed in JWT Header

Impact When n8n was configured with a Google Service Account key, the full PEM private key was mistakenly placed in the JWT header's kid field which should only have held a key identifier. Since JWT headers were Base64-encoded rather than encrypted, the key could be recovered by anything that...

n8n: AI Agents Project Viewer Privilege Escalation via run_node_tool

Impact In n8n's AI Agents feature, a user with the read-only Project Viewer role could escalate their privileges by chatting with an agent that has node tools enabled. The agent's node-execution tool was authorized only by the agent:execute scope and ran nodes using the project's credentials,...
