CVE-2026-81941: Improper Access Control
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...
PT-2026-89591
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...

CVE-2026-85025: Incorrect Authorization
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-2026-81213: Server-Side Request Forgery (SSRF)
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-2026-79724: Improper Neutralization of Special Elements used in an OS Command
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-2026-9225: Authorization Bypass Through User-Controlled Key
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/flowid endpoint, the application allows...
Langflow AI Authenticated Remote Code Execution
Langflow versions 1.11.1 and below are susceptible to authenticated remote code execution. By saving a flow where data.type is empty, an authenticated user can bypass the flow guard and execute arbitrary Python code. https://packetstorm.news/download/231016...
Security Bulletin: Langflow is affected by improper authentication due to missing password verification in the password reset endpoint
Summary Langflow provides a password reset capability through its user management API. The password reset endpoint accepts a current password field in the request body but does not verify it against the stored credential before applying the password change, and enforces no password complexity...
Security Bulletin: Langflow is vulnerable to arbitrary code execution due to multiple incomplete code security controls and missing execution guards
Summary Langflow uses a code security scanner and component-level execution policies to restrict server-side code execution to authorized users and contexts. The agentic assistant code scanner employs an incomplete denylist omitting process-spawning primitives and contains a logic error where...
Security Bulletin: Langflow is vulnerable to server-side request forgery due to missing egress validation on server-side URL fetches
Summary Langflow and its bundled connectors perform server-side HTTP requests using URLs supplied by authenticated users without consistently applying the platform's connector SSRF validation guard. The MCP server configuration URL field accepts any HTTP or HTTPS target including RFC 1918,...
Security Bulletin: Langflow is vulnerable to authentication bypass and insufficient session expiration
Summary Langflow provides API key-based authentication for programmatic access to flow execution and MCP endpoints. The MCP HTTP API credential resolvers do not apply the same AUTOLOGIN API-key guard that all standard authenticated endpoints enforce; when Langflow is in its default AUTOLOGIN...
Security Bulletin: Langflow is vulnerable to unauthorized file system access due to path traversal and missing storage path validation
Summary Langflow uses a local and S3-backed storage service to manage files uploaded by users and referenced by flow components. The flow execution runtime accepts attacker-controlled file paths through the tweaks API without invoking the path containment guard, allowing traversal sequences to...
Security Bulletin: A path traversal vulnerability in file handling components could allow an authenticated attacker to write files to arbitrary locations on the server filesystem
Summary A path traversal vulnerability existed in two independent file handling mechanisms used by the product's workflow execution and file management capabilities. The file upload endpoint accepted multipart filenames directly from HTTP request metadata without sanitization, allowing an...
