CVE-2026-81941 1 Langflow 1 Langflow 2026-09-16 N/A 8.8 HIGH
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.
CVE-2026-81940 1 Langflow 1 Langflow 2026-09-16 N/A 8.8 HIGH
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.
CVE-2026-81268 1 Langflow 1 Langflow 2026-09-16 N/A 8.1 HIGH
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.
CVE-2026-81265 1 Langflow 1 Langflow 2026-09-16 N/A 7.5 HIGH
IBM Langflow OSS 1.0.0 through 1.11.5.
CVE-2026-81213 1 Langflow 1 Langflow 2026-09-16 N/A 8.6 HIGH
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.
CVE-2026-81211 1 Langflow 1 Langflow 2026-09-16 N/A 8.8 HIGH
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.
CVE-2026-81204 1 Langflow 1 Langflow 2026-09-16 N/A 9.8 CRITICAL
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.
CVE-2026-79742 1 Langflow 1 Langflow 2026-09-16 N/A 8.8 HIGH
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.
CVE-2026-79725 1 Langflow 1 Langflow 2026-09-16 N/A 6.5 MEDIUM
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.
CVE-2026-79724 1 Langflow 1 Langflow 2026-09-16 N/A 9.8 CRITICAL
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.
CVE-2026-79723 1 Langflow 1 Langflow 2026-09-16 N/A 5.0 MEDIUM
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.
CVE-2026-78575 1 Langflow 1 Langflow 2026-09-16 N/A 8.8 HIGH
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.
CVE-2026-78571 1 Langflow 1 Langflow 2026-09-16 N/A 8.8 HIGH
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.
CVE-2026-78569 1 Langflow 1 Langflow 2026-09-16 N/A 8.8 HIGH
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.
CVE-2026-76059 1 Langflow 1 Langflow 2026-09-16 N/A 8.8 HIGH
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.
CVE-2026-85025 1 Langflow 1 Langflow 2026-09-15 N/A 9.8 CRITICAL
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.
CVE-2026-9225 1 Langflow 1 Langflow 2026-09-15 N/A 6.5 MEDIUM
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.
CVE-2026-84889 1 Langflow 1 Langflow 2026-09-14 N/A 8.8 HIGH
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.
CVE-2026-9138 4 Apple, Langflow, Linux and 1 more 4 Macos, Langflow, Linux Kernel and 1 more 2026-09-10 N/A 6.5 MEDIUM
IBM Langflow OSS 1.0.0 through 1.11.2 Langflow could allow an authenticated attacker to write arbitrary files to the server due to improper input validation in the SaveToFileComponent. The application constructs local file paths using attacker‑controlled input without sufficient sanitization when handling requests to the /api/v1/run/{flow_id} endpoint. An attacker with low‑privileged authenticated access (such as a valid API key or user session) can supply crafted path values, including absolute paths or path traversal sequences, allowing arbitrary file writes to locations writable by the Langflow process. Successful exploitation may lead to unauthorized file creation or modification, potentially resulting in further compromise depending on the deployment environment.
CVE-2026-19303 4 Apple, Langflow, Linux and 1 more 4 Macos, Langflow, Linux Kernel and 1 more 2026-09-10 N/A 8.1 HIGH
IBM Langflow OSS 1.0.0 through 1.11.2 could allow a remote authenticated attacker to delete arbitrary local files or directories due to improper limitation of a pathname to a restricted directory.
