CVE-2026-110245

IBM Langflow OSS versions 1.0.0 through 1.12.4 contain a vulnerability due to allocation of resources without limits or throttling. A remote authenticated attacker could exploit this to cause a denial of service.

IBM Langflow OSS 1.0.0 through 1.12.3 could allow a remote authenticated attacker to overwrite arbitrary files due to improper limitation of a pathname to a restricted directory.

IBM Langflow OSS 1.0.0 through 1.12.4 could allow a remote authenticated attacker to obtain sensitive information due to improper sanitization of secrets during flow and project exports.

IBM Langflow OSS versions 1.0.0 through 1.12.4 allow a remote attacker to trigger pre-existing stored Python component code in a public workflow, executing it under the flow owner's runtime context within the server process. This bypasses the intended trust boundary where public execution paths are restricted to server-trusted component code.

IBM Langflow OSS 1.0.0 through 1.12.4 could allow a remote authenticated attacker to execute arbitrary commands due to improper control of code generation.

IBM Langflow OSS 1.0.0 through 1.12.4 could allow a remote authenticated attacker to obtain sensitive information due to improper limitation of a pathname to a restricted directory.

IBM Langflow OSS versions 1.0.0 through 1.12.4 could allow a remote authenticated attacker to obtain sensitive information due to cleartext storage of sensitive information. The flaw involves improper protection of such data.

IBM Langflow OSS 1.0.0 through 1.12.4 could allow a remote attacker with a low-privileged authenticated account to bypass the administrator-only restriction and execute arbitrary code on the server by configuring a built-in code-execution component with attacker-supplied inputs.

IBM Langflow OSS 1.0.0 through 1.12.8 could allow a remote attacker with a low-privileged authenticated account to cause the Agentic Assistant to generate or submit component code using these unblocked patterns, resulting in arbitrary operating system command execution on the server.

IBM Langflow OSS versions 1.0.0 through 1.12.8 could allow a remote authenticated attacker to obtain sensitive information due to insufficiently protected credentials. The flaw involves weak protection of authentication data.
