Title
n8n before 2.39.6 and 2.40.x before 2.40.1 Approval Bypass via Send and Wait Node
Summary
n8n versions before 2.39.6 and 2.40.0 before 2.40.1 contain an approval bypass vulnerability in the Send and Wait node's Approve Within Chat mode. Attackers can submit resume requests without verification of the requester's identity or approval permissions, allowing unauthenticated users to advance waiting executions and trigger guarded actions.

Title
n8n before 2.39.6 and 2.40.x before 2.40.1 Session Token Leak via Dynamic Credentials
Summary
n8n versions before 2.39.6 and 2.40.0 before 2.40.1 contain a session token leakage vulnerability in the Dynamic Credentials authorize and revoke endpoints. Attackers with resolver registration capability can capture collaborators' session tokens by setting a fallback resolver to an attacker-controlled endpoint during the account connection flow, enabling unauthorized credential access.

Title
n8n before 2.39.6 and 2.40.x before 2.40.1 Filter Bypass via Parameter Interpolation
Summary
n8n versions before 2.39.6 and 2.40.0 before 2.40.1 contain an unescaped parameter interpolation vulnerability in SendGrid, Freshservice, and ServiceNow nodes that allows attackers to bypass filters by breaking out of query literals. Attackers can exploit this by binding vulnerable node parameters to untrusted external input to widen single-record lookups into match-all queries, exposing bulk data including contact lists, tickets, and directory entries.

Title
n8n before 1.123.80, 2.39.6, and 2.40.1 Path Traversal via n8n Node
Summary
n8n versions before 1.123.80, from 2.0.0 before 2.39.6, and from 2.40.0 before 2.40.1 contain a path traversal vulnerability in the n8n node that fails to validate resource identifiers. Attackers can craft malicious resource IDs to redirect API calls to unintended resources, allowing unauthorized access to workflows, executions, and credential secrets within the API key's scope.

Title
n8n before 2.39.6 and 2.40.x before 2.40.1 Credentials Leak via preAuthentication Hook
Summary
n8n versions before 2.39.6 and 2.40.0 before 2.40.1 contain a credentials leak vulnerability in the Wekan and Baserow username-and-password credentials that sends unencrypted passwords to unvalidated hosts. Attackers with credential update permissions can modify the host field to receive account passwords at arbitrary hosts, bypassing domain validation controls.

Summary
n8n versions before 1.123.80, from 2.0.0 before 2.39.6, and from 2.40.0 before 2.40.1 contain a path traversal vulnerability in the Supabase node where the tableId parameter is inserted into request paths without validation. Attackers can exploit workflows binding tableId to untrusted input to traverse to Auth and Storage APIs using the administrative serviceRole key, bypassing Row Level Security and enabling unauthorized data access and modification.

n8n before 1.123.80, 2.39.6, and 2.40.1 Path Traversal via Resume URL Generation
Summary
n8n versions before 1.123.80, from 2.0.0 before 2.39.6, and from 2.40.0 before 2.40.1 contain a path traversal vulnerability in signed resume URL generation for Send-and-Wait approvals. Attackers with workflow creation permissions can mint valid approval URLs for gates in projects they cannot access by exploiting unresolved traversal sequences in caller-controlled node IDs, enabling cross-project approval forgery.

Title
n8n before 1.123.80, 2.39.6, and 2.40.1 SQL Injection via Oracle Database Drop Table
Summary
n8n versions before 1.123.80, from 2.0.0 before 2.39.6, and from 2.40.0 before 2.40.1 contain an SQL injection vulnerability in the Oracle Database node's Delete Table Drop operation. Attackers can inject single quotes in the table or schema fields to append arbitrary SQL statements and execute DDL or DML commands against the connected database with the credential's privileges.

Title
n8n before 1.123.80, 2.39.6, and 2.40.1 Information Disclosure via Credential Test Endpoint
Summary
n8n versions before 1.123.80, from 2.0.0 before 2.39.6, and from 2.40.0 before 2.40.1 contain an authorization bypass vulnerability in the credential test endpoint that resolves project-scoped variables without validating caller access. Attackers can specify an arbitrary project ID in the request body to interpolate sensitive variables into credential test requests sent to attacker-controlled hosts for exfiltration.

Unauthenticated attackers can supply MongoDB query operators in the sessionId field to access conversation histories from other users and perform unauthorized write and delete operations.

Title
n8n before 2.39.6 and 2.40.x before 2.40.1 Session Token Leak via Dynamic Credentials
Summary
n8n versions before 2.39.6 and 2.40.0 before 2.40.1 contain a session token leakage vulnerability in the Dynamic Credentials authorize and revoke endpoints. Attackers with resolver registration capability can capture collaborators' session tokens by setting a fallback resolver to an attacker-controlled endpoint during the account connection flow, enabling unauthorized credential access.

Title
n8n before 2.39.6 and 2.40.x before 2.40.1 Filter Bypass via Parameter Interpolation
Summary
n8n versions before 2.39.6 and 2.40.0 before 2.40.1 contain an unescaped parameter interpolation vulnerability in SendGrid, Freshservice, and ServiceNow nodes that allows attackers to bypass filters by breaking out of query literals. Attackers can exploit this by binding vulnerable node parameters to untrusted external input to widen single-record lookups into match-all queries, exposing bulk data including contact lists, tickets, and directory entries.

n8n before 2.39.6 and 2.40.x before 2.40.1 Credentials Leak via preAuthentication Hook
Summary
n8n versions before 2.39.6 and 2.40.0 before 2.40.1 contain a credentials leak vulnerability in the Wekan and Baserow username-and-password credentials that sends unencrypted passwords to unvalidated hosts. Attackers with credential update permissions can modify the host field to receive account passwords at arbitrary hosts, bypassing domain validation controls.

Title
n8n before 1.123.80, 2.39.6, and 2.40.1 Path Traversal and Query Injection via Supabase
Summary
n8n versions before 1.123.80, from 2.0.0 before 2.39.6, and from 2.40.0 before 2.40.1 contain a path traversal vulnerability in the Supabase node where the tableId parameter is inserted into request paths without validation. Attackers can exploit workflows binding tableId to untrusted input to traverse to Auth and Storage APIs using the administrative serviceRole key, bypassing Row Level Security and enabling unauthorized data access and modification.

Summary
n8n versions before 1.123.80, from 2.0.0 before 2.39.6, and from 2.40.0 before 2.40.1 contain a path traversal vulnerability in signed resume URL generation for Send-and-Wait approvals. Attackers with workflow creation permissions can mint valid approval URLs for gates in projects they cannot access by exploiting unresolved traversal sequences in caller-controlled node IDs, enabling cross-project approval forgery.

Title
n8n before 1.123.80, 2.39.6, and 2.40.1 Information Disclosure via Credential Test Endpoint
Summary
n8n versions before 1.123.80, from 2.0.0 before 2.39.6, and from 2.40.0 before 2.40.1 contain an authorization bypass vulnerability in the credential test endpoint that resolves project-scoped variables without validating caller access. Attackers can specify an arbitrary project ID in the request body to interpolate sensitive variables into credential test requests sent to attacker-controlled hosts for exfiltration.

Summary
n8n versions before 1.123.80, from 2.0.0 before 2.39.6, and from 2.40.0 before 2.40.1 contain a stored DOM cross-site scripting vulnerability in Resource Locator parameter dropdown link handling. Workflow authors can inject malicious script URLs that execute arbitrary JavaScript in the editor origin when other users open the node dropdown and click the external-link icon, with the payload persisting across workflow imports and shares.

Title
n8n before 1.123.80, 2.39.6, and 2.40.1 PostgREST Filter Injection via Supabase
Summary
n8n versions before 1.123.80, from 2.0.0 before 2.39.6, and from 2.40.0 before 2.40.1 contain a filter injection vulnerability in the Supabase node's Filters (String) mode that fails to escape field values. Attackers can inject filter expressions from untrusted input to read all table rows, update all records, or delete entire tables in a single request.

Title
n8n before 1.123.80 Credential Tampering via Duplicate Node IDs
Summary
n8n versions before 1.123.80 contain a credential tampering vulnerability where duplicate node IDs bypass the workflow credential tamper guard. Attackers with editor access to shared workflows can exploit mismatched node ID and name matching to retain victim credentials and redirect secrets to attacker-controlled hosts.
