n8n: External Secrets Permission Bypass via Expression Parser Mismatch

Impact Due to a mismatch between the static validation check and the runtime expression engine, an authenticated user with credential create or update permissions, but without the externalSecret:list scope, could embed external secret references into credentials in forms the validation did not...

GHSA-JP7M-XCGX-57QM n8n: External Secrets Permission Bypass via Expression Parser Mismatch

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...

Prototype Pollution

Overview n8n-core is a Core functionality of n8n Affected versions of this package are vulnerable to Prototype Pollution in the expression engine. An attacker can cause the application to become unresponsive or crash by manipulating array-element access to obtain a reference to a host built-in an...

GHSA-6QC9-MQVW-JG7X n8n: Credential Authorization Bypass via Expression in HTTP Request Node `genericAuthType`

Impact An authenticated member with edit access to a shared workflow could reference another user's credential in an HTTP Request node while specifying the credential type through an expression. Because the pre-execution permission check compared the unresolved expression instead of the real...

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...

n8n: Legacy Expression Evaluator Sanitizer Bypass Leads to Authenticated Code Execution

Impact The legacy expression evaluator's computed-member sanitizer can be bypassed by an authenticated user with workflow create or modify permissions. Successful exploitation grants the attacker host-level code execution as the n8n process. The legacy expression engine is the default engine in...

Improper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection')

Overview n8n is a n8n Workflow Automation Tool Affected versions of this package are vulnerable to Improper Neutralization of Special Elements used in an Expression Language Statement 'Expression Language Injection' via the legacy expression evaluator's computed-member sanitizer. An attacker can...

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...

CVE-2026-9737

During query planning when reading the sort pattern in raw BSONObj form, in some places we don’t explicitly handle the meta expression case. This may lead to incorrect transformations leading to invariant failure...

CVE-2026-13065

A user with read-only privileges is able to craft an aggregation pipeline using the $linearFill window function operator with a specific sortBy expression type to cause the mongod process to terminate abnormally, resulting in denial of service. The issue stems from insufficient validation of sort...
