Title
Langflow is affected by remote code execution, denial of service, path traversal, and exposed credentials due to multiple unauthenticated and insufficiently authorized API endpoints
Summary
IBM Langflow OSS 1.0.0 through 1.10.1 can allow an authenticated attacker to exploit the SaveToFile component to read and modify another user's uploaded files by specifying absolute paths pointing to victim storage locations. In append mode, the attacker's workflow reads victim file contents, appends attacker-controlled data, and uploads a copy containing victim data to the attacker's namespace (confidentiality breach). In overwrite mode, the attacker can replace victim file contents with arbitrary data (integrity breach). This breaks the storage ownership boundary between users.

Title
Path Traversal in APIRequest Component via Content-Disposition Header
Summary
IBM Langflow OSS 1.0.0 through 1.10.0 Langflow could allow an attacker to write arbitrary files to unintended locations due to improper input validation in the APIRequest component. A path traversal vulnerability exists when the "Save to File" feature is enabled, where filenames extracted from HTTP response Content-Disposition headers are not sanitized before being joined to the temporary directory path. An attacker controlling an external HTTP server can supply crafted filename values containing path traversal sequences (e.g., ../), enabling arbitrary file writes to locations accessible by the Langflow process.

Title
Authentication Bypass in Webhook Endpoints Allowed Unauthorized Flow Execution
Summary
IBM Langflow OSS 1.0.0 through 1.10.0 has a vulnerability in Langflow's webhook authentication logic allows unauthenticated users to trigger the execution of any flow. The system incorrectly bypasses API key validation when the WEBHOOK_AUTH_ENABLE configuration is set to False (which is the default setting). This allows a remote attacker who knows a flow's UUID to execute it as if they were the owner, potentially leading to Remote Code Execution (RCE).

Title
Remote Code Execution via Code Validation Endpoint
Summary
IBM Langflow OSS 1.0.0 through 1.10.0 contain a critical remote code execution vulnerability in the code validation API endpoint. The POST /api/v1/validate/code endpoint accepts user-supplied Python code and executes it directly using Python's built-in exec() function without sandboxing, input validation, or privilege restrictions, enabling any authenticated user to execute arbitrary system commands with the full privileges of the Langflow server process.

Title
Disk Cache Deserialization Remote Code Execution Vulnerability
Summary
IBM Langflow OSS 1.0.0 through 1.10.0 contain a critical remote code execution vulnerability in the disk-based caching mechanism. The AsyncDiskCache class uses Python's unsafe pickle.loads() function to deserialize cached objects from disk without validation, integrity verification, or authentication, enabling arbitrary code execution when malicious pickle payloads are processed. Attackers who can influence cached data through file system access, malicious workflow inputs, custom components, or API manipulation can achieve complete system compromise with the privileges of the Langflow server process.

Title
Langflow is affected by remote code execution, denial of service, path traversal, and exposed credentials due to multiple unauthenticated and insufficiently authorized API endpoints
Summary
IBM Langflow OSS 1.0.0 through 1.10.1 Lanflow OSS contains an unauthenticated remote code execution vulnerability in the public flow build endpoint ( /api/v1/build_public_tmp/{flow_id}/flow ). The vulnerability stems from an incomplete denylist in the validate_public_flow_no_code_execution() function that fails to block several code-execution agent components including OpenDsStarAgent, CodeActAgentSmolagents, and CSVAgent.

Title
Policies Component Dynamic CodeInput Fields Bypass Custom Component Validation
Summary
IBM Langflow OSS 1.0.0 through 1.10.0 Langflow versions up to 1.9.2 (commit 94981c443d4918517b9e8163d70fc598dc33a32d) contain a code injection vulnerability in the Policies component's ToolGuard integration that bypasses the allow_custom_components=false security control. The vulnerability exists because the validation mechanism only checks the main component source code in node_template["code"]["value"] but fails to validate dynamic CodeInput fields that store generated ToolGuard Python files. Attackers can embed malicious Python code in these unvalidated dynamic fields, which are persisted in Flow.data and later executed server-side when a guarded tool is invoked through the ToolGuard runtime. This allows authenticated users with flow creation privileges to achieve arbitrary Python code execution on the backend despite custom component restrictions. The vulnerability can be escalated through cross-tenant flow manipulation via the agentic MCP update_flow_component_field tool, which accepts attacker-controlled user_id parameters, enabling attackers to inject malicious code into victim users' flows. When combined with publicly accessible flows and specific misconfigurations (AUTO_LOGIN=true, NEW_USER_IS_ACTIVE=true), the attack can be conducted with reduced authentication requirements.

Title
Unauthenticated Superuser Token Issuance via Auto-Login Endpoint
Summary
IBM Langflow OSS 1.0.0 through 1.10.0 could allow a remote attacker to gain unauthorized access due to improper authentication in the /api/v1/login/auto_login endpoint. The endpoint issues long-lived superuser bearer tokens without requiring authentication when the AUTO_LOGIN configuration is enabled (enabled by default), which may allow an unauthenticated network attacker to obtain full administrative access. Additionally, permissive cross-origin resource sharing (CORS) settings may allow tokens to be exposed to unintended origins, increasing the risk of unauthorized access.

CVE-2026-13445 (GCVE-0-2026-13445)
Vulnerability from cvelistv5 – Published: 2026-07-17 20:44 – Updated: 2026-07-20 19:11

Title
Langflow is affected by remote code execution, denial of service, path traversal, and exposed credentials due to multiple unauthenticated and insufficiently authorized API endpoints
Summary
IBM Langflow OSS 1.0.0 through 1.10.1 can allow an authenticated attacker to exploit the SaveToFile component to read and modify another user's uploaded files by specifying absolute paths pointing to victim storage locations. In append mode, the attacker's workflow reads victim file contents, appends attacker-controlled data, and uploads a copy containing victim data to the attacker's namespace (confidentiality breach). In overwrite mode, the attacker can replace victim file contents with arbitrary data (integrity breach). This breaks the storage ownership boundary between users.

Title
Langflow is affected by remote code execution, denial of service, path traversal, and exposed credentials due to multiple unauthenticated and insufficiently authorized API endpoints
Summary
IBM Langflow OSS 1.0.0 through 1.10.1 Lanflow OSS contains an unauthenticated remote code execution vulnerability in the public flow build endpoint ( /api/v1/build_public_tmp/{flow_id}/flow ). The vulnerability stems from an incomplete denylist in the validate_public_flow_no_code_execution() function that fails to block several code-execution agent components including OpenDsStarAgent, CodeActAgentSmolagents, and CSVAgent.

Title
Disk Cache Deserialization Remote Code Execution Vulnerability
Summary
IBM Langflow OSS 1.0.0 through 1.10.0 contain a critical remote code execution vulnerability in the disk-based caching mechanism. The AsyncDiskCache class uses Python's unsafe pickle.loads() function to deserialize cached objects from disk without validation, integrity verification, or authentication, enabling arbitrary code execution when malicious pickle payloads are processed. Attackers who can influence cached data through file system access, malicious workflow inputs, custom components, or API manipulation can achieve complete system compromise with the privileges of the Langflow server process.

Title
Remote Code Execution via Code Validation Endpoint
Summary
IBM Langflow OSS 1.0.0 through 1.10.0 contain a critical remote code execution vulnerability in the code validation API endpoint. The POST /api/v1/validate/code endpoint accepts user-supplied Python code and executes it directly using Python's built-in exec() function without sandboxing, input validation, or privilege restrictions, enabling any authenticated user to execute arbitrary system commands with the full privileges of the Langflow server process.

Title
Authentication Bypass in Webhook Endpoints Allowed Unauthorized Flow Execution
Summary
IBM Langflow OSS 1.0.0 through 1.10.0 has a vulnerability in Langflow's webhook authentication logic allows unauthenticated users to trigger the execution of any flow. The system incorrectly bypasses API key validation when the WEBHOOK_AUTH_ENABLE configuration is set to False (which is the default setting). This allows a remote attacker who knows a flow's UUID to execute it as if they were the owner, potentially leading to Remote Code Execution (RCE).

Title
Path Traversal in APIRequest Component via Content-Disposition Header
Summary
IBM Langflow OSS 1.0.0 through 1.10.0 Langflow could allow an attacker to write arbitrary files to unintended locations due to improper input validation in the APIRequest component. A path traversal vulnerability exists when the "Save to File" feature is enabled, where filenames extracted from HTTP response Content-Disposition headers are not sanitized before being joined to the temporary directory path. An attacker controlling an external HTTP server can supply crafted filename values containing path traversal sequences (e.g., ../), enabling arbitrary file writes to locations accessible by the Langflow process.
Severity
9.9 (Critical)
