CVSS v3.1 |
| IBM Langflow OSS 1.0.0 through 1.11.5 Langflow could allow an authenticated attacker to access sensitive files belonging to other users due to improper access control in the File/Read File component. When executing flows through the /api/v1/run/advanced/{flow_id} endpoint, the application allows component inputs to reference storage paths using arbitrary user or flow identifiers without verifying ownership. An attacker with low‑privileged authenticated access can supply a crafted file path pointing to another user’s storage namespace, causing the backend to read and return the contents of files uploaded by other users. This vulnerability bypasses intended authorization checks enforced by the file management API and may result in unauthorized disclosure of sensitive user data. |
| IBM Langflow OSS 1.0.0 through 1.11.5. |
| IBM Langflow OSS 1.0.0 through 1.11.5 could allow a remote attacker to execute arbitrary code due to code injection during graph construction. |
| IBM Langflow OSS 1.0.0 through 1.11.5 could allow a remote authenticated attacker to execute arbitrary commands due to improper validation of command-line arguments in the MCP stdio server configuration. |
| IBM Langflow OSS 1.0.0 through 1.11.5 Langflow could allow an unauthenticated attacker to execute arbitrary code and access or modify chat sessions through publicly shared MCP project endpoints due to improper enforcement of public-flow security restrictions and session isolation controls. |
| IBM Langflow OSS 1.0.0 through 1.11.5 could allow a remote authenticated attacker to execute flows and obtain sensitive information due to insufficient session expiration of API keys after user deactivation. |
| IBM Langflow OSS 1.0.0 through 1.11.5 could allow a remote authenticated attacker to obtain sensitive information due to improper validation of user-controlled API endpoints. |
| IBM Langflow OSS 1.0.0 through 1.11.5 An attacker who could submit custom component source code could bypass the static security scanner by crafting an annotated class-body assignment that resolved to a dangerous callable through alias tracking; the resolved value was never checked against the dangerous callable blocklist due to the logic error. If the crafted component reached the runtime execution path, the attacker could cause arbitrary operating system commands to execute on the server in-process, with the privileges of the running service. |
| IBM Langflow OSS 1.0.0 through 1.11.5 could allow an authenticated attacker to execute arbitrary code due to an incomplete denylist in the security scanner. |
| IBM Langflow OSS 1.0.0 through 1.11.5 could allow a remote authenticated attacker to execute arbitrary code due to an unguarded eval() call on attacker-controlled input. |
| IBM Langflow OSS 1.0.0 through 1.11.5 could allow a remote attacker to execute arbitrary OS commands due to improper neutralization of special elements used in an OS command. |
| IBM Langflow OSS 1.0.0 through 1.11.5 could allow a remote authenticated attacker to read arbitrary files due to improper access control. |
| IBM Langflow OSS 1.0.0 through 1.11.5 could allow a remote authenticated attacker to execute arbitrary code due to an incomplete environment variable blocklist. |
| IBM Langflow OSS 1.0.0 through 1.11.5 could allow a remote authenticated attacker to execute arbitrary Python code due to improper authorization of custom components in stored flows. |
| IBM Langflow OSS 1.0.0 through 1.11.5 allows an authenticated non-administrative user could execute arbitrary operating system commands on the server at the privilege level of the application process by constructing a flow with an MCP Tools component configured to use a local stdio subprocess transport. This bypasses both the LANGFLOW_CUSTOM_COMPONENT_ADMIN_ONLY and LANGFLOW_BLOCK_CODE_INTERPRETER_COMPONENTS server-side controls intended to prevent exactly this class of access. Successful exploitation could lead to arbitrary command execution, sensitive data exposure (including credentials from the process environment), file system modification, and lateral movement to services reachable from the server. |
| IBM Langflow OSS 1.0.0 through 1.11.5 could allow a remote attacker to obtain sensitive information from internal network resources due to improper validation of user-supplied URLs. |
| IBM Langflow OSS 1.0.0 through 1.11.5 could allow a remote authenticated attacker to execute arbitrary code due to improper neutralization of special characters in flow display names. |
| IBM Langflow OSS 1.0.0 through 1.10.3 could allow a remote authenticated attacker to execute arbitrary code due to improper limitation of a pathname to a restricted directory. |
| IBM Langflow OSS 1.0.0 through 1.11.2 could allow a remote authenticated attacker to execute arbitrary code due to an authorization bypass in the flow build process. |
| IBM Langflow OSS 1.0.0 through 1.10.2 could allow an authenticated attacker to traverse directories on the system. An attacker could send a specially crafted URL request containing "dot dot" sequences (/../) to view arbitrary files on the system. |
