Title
n8n before 1.123.67 SQL Injection via PostgresTrigger Node
Summary
n8n before 1.123.67, 2.31.5, and 2.32.1 contains a SQL injection vulnerability in the PostgresTrigger node, which interpolates user-supplied identifier parameters (channel, function, and trigger names) into SQL statements without proper escaping. An authenticated user can inject arbitrary SQL executed against the connected PostgreSQL database with the configured credential's privileges, allowing full read and write access.

Title
n8n before 1.123.67 Authentication Bypass via HTTP Request Node
Summary
n8n before 1.123.67, 2.31.5, and 2.32.1 contains a credential authorization bypass in the HTTP Request node. An authenticated member with edit access to a shared workflow can reference another user's credential while specifying the credential type via an expression. Because the pre-execution permission check compares the unresolved expression instead of the resolved credential type, the ownership check is skipped and the credential is loaded at execution time, allowing the member to use or exfiltrate a credential they were not granted. Exploitation requires knowing the target credential's identifier.

Title
n8n before 2.32.1 Path Traversal via computer-use search_files
Summary
n8n before 2.31.5 and 2.32.x before 2.32.1 contain a path-confinement bypass in the @n8n/computer-use file-search (search_files) tool. A crafted search pattern can bypass the base-directory confinement check and expand to locations outside the configured directory, causing the tool to return the names and contents of arbitrary local files readable by the daemon's OS user. Any deployment where an actor can influence the tool's search input is affected.

Title
n8n before 2.32.1 Authentication Bypass via Token Exchange
Summary
n8n before 2.32.1 (and before 2.31.5) is vulnerable to account takeover via the Token Exchange Embed Login feature. When a validly-signed incoming token was matched to a local account by its email claim, the service did not verify that the email claim was verified, nor that the trusted key's permitted role ceiling covered that account. As a result, anyone able to obtain a token accepted by a configured trusted key (for example, a trusted issuer emitting unverified email addresses) could authenticate as any existing user and gain full account control. This issue only affects instances where the embed login feature is enabled and at least one trusted key source is configured.

Title
n8n before 2.32.1 Credential Restriction Bypass via AI/LLM Nodes
Summary
n8n versions before 2.32.1 fail to enforce the Allowed HTTP Request Domains allowlist in multiple AI and LLM nodes when user-supplied base or endpoint URLs are configured. Low-privileged workflow editors with use-only access to shared credentials can redirect requests to attacker-controlled hosts and exfiltrate credential secrets for reuse against underlying services.

Title
n8n before 1.123.67 Path Traversal via Git Node Operations
Summary
n8n versions before 1.123.67 contain a path traversal vulnerability in the Git node's fetch, pull, and push-tags operations that allows authenticated users to bypass repository-path containment checks. Attackers with workflow create/execute rights can point allowlisted remote configurations at local paths outside the sandbox to pull arbitrary git repositories and read their files and history.

Title
n8n before 1.123.67 Prototype Pollution via VM Expression Engine
Summary
n8n before 1.123.67, 2.31.5, and 2.32.1 contains a prototype pollution vulnerability in the VM expression engine. An authenticated user able to create or edit a workflow expression can abuse the engine's array-element access to obtain a reference to a host built-in and pollute its prototype in the main n8n process (a sandbox escape), leading to a denial of service. Both self-hosted and cloud instances running the VM expression engine are affected.

Title
n8n before 2.32.1 SSRF Protection Bypass via MCP Client
Summary
n8n versions before 2.32.1 contain a server-side request forgery protection bypass vulnerability in the MCP Client node that allows authenticated users to bypass SSRF protections. Attackers can craft workflows that send requests to internal or blocked hosts without routing through SSRF protection, exposing internal services and reading responses back through the workflow.

Title
n8n before 1.123.67 Remote Code Execution via Git node
Summary
n8n before 1.123.67, 2.x before 2.31.5, and 2.32.x before 2.32.1 contain a remote code execution vulnerability in the Git node. Authenticated users with rights to create and execute workflows can stage a crafted local repository that causes git to run hooks under default git security settings, executing arbitrary commands as the n8n process user. Both self-hosted and cloud instances are affected.

Title
n8n before 1.123.67 Arbitrary File Read via Send Email Node
Summary
n8n before 1.123.67, 2.x before 2.31.5, and 2.32.x before 2.32.1 contain a type confusion vulnerability in the Send Email node, which does not enforce that its message fields are strings. A crafted non-string value supplied from a workflow expression into the text or HTML body field can be interpreted by the underlying mail library (Nodemailer) as a file path or URL, allowing arbitrary local file disclosure and server-side request forgery (SSRF). Exploitation requires a pre-existing active workflow with an unauthenticated webhook, valid SMTP credentials configured on the node, and untrusted input mapped directly into the body field; this is not a default configuration.

Title
n8n before 2.32.1 Remote Code Execution via Expression Sandbox Escape
Summary
n8n before 2.31.5 and before 2.32.1 contain a sandbox escape vulnerability in expression evaluation. An authenticated user with permission to create or modify workflows can craft expressions using arrow-function bodies to bypass the expression sandbox, triggering system command execution on the host running n8n. The issue is fixed in versions 2.31.5 and 2.32.1.

Title
n8n before 1.123.67 Module Cache Poisoning via Code Node
Summary
n8n's JavaScript task runner shared a single module cache across all users' Code-node executions. In affected versions (before 1.123.67, 2.31.5, and 2.32.1), a user able to run a Code node could poison a cached module and thereby alter other users' Code-node executions on the same runner, affecting their confidentiality, integrity, or availability. This is a cross-user isolation break within a single n8n instance and does not constitute a sandbox escape or remote code execution. Only multi-user instances running the JS task runner with built-in or external modules enabled are affected.

Title
n8n before 1.123.67 Credential Exfiltration via Sub-Workflow
Summary
n8n before 1.123.67, 2.31.5, and 2.32.1 validates credential-access only for a node's top-level credentials and not for credentials referenced inside an Execute Sub-workflow node's inline workflow JSON. A member with Editor access to a shared workflow (when workflow sharing is enabled) who knows a target credential's ID can reference that credential in the inline JSON; it passes save-time and runtime validation and resolves in the parent workflow's project context, allowing the attacker to use or exfiltrate credentials they are not permitted to access.

n8n before 1.123.67 Arbitrary File Write via Edit Image Node
Summary
n8n versions before 1.123.67, 2.31.5, and 2.32.1 contain an arbitrary file write vulnerability in the Edit Image node, which passes its output format parameter to the underlying image library without validation. An authenticated user able to run workflows can supply a crafted format value to write arbitrary files outside the node's working directory on the n8n instance.

Title
n8n before 1.123.67 SQL Injection via executeQuery Operation
Summary
n8n before 1.123.67, 2.31.5, and 2.32.1 contains a SQL injection vulnerability in the Snowflake node's Execute Query operation, which interpolates expression values directly into the SQL string. When a workflow author embeds untrusted, externally-controlled expression data directly in a raw SQL query, that data is not parameterized, allowing SQL injection. The fix adds an optional 'Query Parameters' field to bind values via positional placeholders.

Title
n8n before 1.123.67 Prototype Pollution via Edit Fields
Summary
n8n before 1.123.67, 2.31.5, and 2.32.1 contains a prototype pollution vulnerability in the Edit Fields (Set) node. The node assigns output fields via a dot-notation path setter without restricting the field name, allowing an authenticated user to name a field after an inherited built-in method path and corrupt a shared global in the main Node.js process. Because that global is used on the request-authentication path, the instance then fails every authenticated request, causing an instance-wide denial of service for all users until the process is restarted.

Title
n8n before 1.123.67 Authentication Bypass via HTTP Request Node
Summary
n8n before 1.123.67, 2.31.5, and 2.32.1 contains a credential authorization bypass in the HTTP Request node. An authenticated member with edit access to a shared workflow can reference another user's credential while specifying the credential type via an expression. Because the pre-execution permission check compares the unresolved expression instead of the resolved credential type, the ownership check is skipped and the credential is loaded at execution time, allowing the member to use or exfiltrate a credential they were not granted. Exploitation requires knowing the target credential's identifier.

Title
n8n before 2.32.1 Path Traversal via computer-use search_files
Summary
n8n before 2.31.5 and 2.32.x before 2.32.1 contain a path-confinement bypass in the @n8n/computer-use file-search (search_files) tool. A crafted search pattern can bypass the base-directory confinement check and expand to locations outside the configured directory, causing the tool to return the names and contents of arbitrary local files readable by the daemon's OS user. Any deployment where an actor can influence the tool's search input is affected.

Title
n8n before 2.32.1 Authentication Bypass via Token Exchange
Summary
n8n before 2.32.1 (and before 2.31.5) is vulnerable to account takeover via the Token Exchange Embed Login feature. When a validly-signed incoming token was matched to a local account by its email claim, the service did not verify that the email claim was verified, nor that the trusted key's permitted role ceiling covered that account. As a result, anyone able to obtain a token accepted by a configured trusted key (for example, a trusted issuer emitting unverified email addresses) could authenticate as any existing user and gain full account control. This issue only affects instances where the embed login feature is enabled and at least one trusted key source is configured.

n8n before 2.32.1 Credential Restriction Bypass via AI/LLM Nodes
Summary
n8n versions before 2.32.1 fail to enforce the Allowed HTTP Request Domains allowlist in multiple AI and LLM nodes when user-supplied base or endpoint URLs are configured. Low-privileged workflow editors with use-only access to shared credentials can redirect requests to attacker-controlled hosts and exfiltrate credential secrets for reuse against underlying services.

Title
n8n before 1.123.67 Path Traversal via Git Node Operations
Summary
n8n versions before 1.123.67 contain a path traversal vulnerability in the Git node's fetch, pull, and push-tags operations that allows authenticated users to bypass repository-path containment checks. Attackers with workflow create/execute rights can point allowlisted remote configurations at local paths outside the sandbox to pull arbitrary git repositories and read their files and history.

Title
n8n before 1.123.67 Prototype Pollution via VM Expression Engine
Summary
n8n before 1.123.67, 2.31.5, and 2.32.1 contains a prototype pollution vulnerability in the VM expression engine. An authenticated user able to create or edit a workflow expression can abuse the engine's array-element access to obtain a reference to a host built-in and pollute its prototype in the main n8n process (a sandbox escape), leading to a denial of service. Both self-hosted and cloud instances running the VM expression engine are affected.

Summary
n8n before 1.123.67, 2.x before 2.31.5, and 2.32.x before 2.32.1 contain a remote code execution vulnerability in the Git node. Authenticated users with rights to create and execute workflows can stage a crafted local repository that causes git to run hooks under default git security settings, executing arbitrary commands as the n8n process user. Both self-hosted and cloud instances are affected.

Title
n8n before 1.123.67 Arbitrary File Read via Send Email Node
Summary
n8n before 1.123.67, 2.x before 2.31.5, and 2.32.x before 2.32.1 contain a type confusion vulnerability in the Send Email node, which does not enforce that its message fields are strings. A crafted non-string value supplied from a workflow expression into the text or HTML body field can be interpreted by the underlying mail library (Nodemailer) as a file path or URL, allowing arbitrary local file disclosure and server-side request forgery (SSRF). Exploitation requires a pre-existing active workflow with an unauthenticated webhook, valid SMTP credentials configured on the node, and untrusted input mapped directly into the body field; this is not a default configuration.

n8n before 2.32.1 Remote Code Execution via Expression Sandbox Escape
Summary
n8n before 2.31.5 and before 2.32.1 contain a sandbox escape vulnerability in expression evaluation. An authenticated user with permission to create or modify workflows can craft expressions using arrow-function bodies to bypass the expression sandbox, triggering system command execution on the host running n8n. The issue is fixed in versions 2.31.5 and 2.32.1.

Title
n8n before 1.123.67 Module Cache Poisoning via Code Node
Summary
n8n's JavaScript task runner shared a single module cache across all users' Code-node executions. In affected versions (before 1.123.67, 2.31.5, and 2.32.1), a user able to run a Code node could poison a cached module and thereby alter other users' Code-node executions on the same runner, affecting their confidentiality, integrity, or availability. This is a cross-user isolation break within a single n8n instance and does not constitute a sandbox escape or remote code execution. Only multi-user instances running the JS task runner with built-in or external modules enabled are affected.

Title
n8n before 1.123.67 Credential Exfiltration via Sub-Workflow
Summary
n8n before 1.123.67, 2.31.5, and 2.32.1 validates credential-access only for a node's top-level credentials and not for credentials referenced inside an Execute Sub-workflow node's inline workflow JSON. A member with Editor access to a shared workflow (when workflow sharing is enabled) who knows a target credential's ID can reference that credential in the inline JSON; it passes save-time and runtime validation and resolves in the parent workflow's project context, allowing the attacker to use or exfiltrate credentials they are not permitted to access.

Title
n8n before 1.123.67 Arbitrary File Write via Edit Image Node
Summary
n8n versions before 1.123.67, 2.31.5, and 2.32.1 contain an arbitrary file write vulnerability in the Edit Image node, which passes its output format parameter to the underlying image library without validation. An authenticated user able to run workflows can supply a crafted format value to write arbitrary files outside the node's working directory on the n8n instance.
