CVE-2026-76059

IBM Langflow OSS versions 1.0.0 through 1.11.5 are affected by a protection mechanism failure (CWE-693) in its static code security scanner. An attacker who can submit custom component source code can bypass the scanner by crafting an annotated class-body assignment that resolves to a dangerous c...

CVE-2026-78569

IBM Langflow OSS (versions 1.0.0 through 1.11.5) is vulnerable to arbitrary code execution by an authenticated attacker due to an incomplete denylist in its agentic assistant code security scanner. The scanner omits process-spawning primitives and contains a logic error where annotated class-body...

CVE-2026-78571 Langflow is vulnerable to arbitrary code execution due to multiple incomplete code security controls and missing execution guards

CVE-2026-78575

IBM Langflow OSS 1.0.0–1.11.5 is vulnerable to OS command injection (CWE-78) in the MCP stdio server configuration , allowing a remote authenticated attacker to execute arbitrary commands. The root cause involves two gaps: the MCP stdio validator on Windows recognizes only one cmd.exe execution s...

CVE-2026-79724

IBM Langflow OSS versions 1.0.0 through 1.11.5 are affected by an OS command injection vulnerability (CWE-78) caused by multiple incomplete code security controls and missing execution guards, including an incomplete denylist omitting process-spawning primitives, a logic error in the code scanner...

CVE-2026-81213 Langflow is vulnerable to server-side request forgery due to missing egress validation on server-side URL fetches

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-2026-81268 Langflow is vulnerable to authentication bypass and insufficient session expiration

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-2026-84889 A path traversal vulnerability in file handling components could allow an authenticated attacker to write files to arbitrary locations on the server filesystem

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-2026-84889

IBM Langflow OSS versions 1.0.0 through 1.10.3 contain a path traversal vulnerability (CWE-22) in two independent file handling mechanisms. First, the file upload endpoint accepted multipart filenames from HTTP request metadata without sanitization, allowing directory traversal sequences in the C...

CVE-2026-84889 A path traversal vulnerability in file handling components could allow an authenticated attacker to write files to arbitrary locations on the server filesystem

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-2026-9225

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...

CVE-2026-85025

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-2026-85025

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...

EUVD-2026-75748

EUVD-2026-75723

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...

PT-2026-89616

Name of the Vulnerable Software and Affected Versions IBM Langflow OSS versions 1.0.0 through 1.11.5 Description Improper validation of user-controlled API endpoints allows a remote authenticated attacker to obtain sensitive information. Recommendations At the moment, there is no information abou...

PT-2026-89645

Name of the Vulnerable Software and Affected Versions IBM Langflow OSS versions 1.0.0 through 1.10.3 Description A remote authenticated attacker can execute arbitrary code because the software does not properly limit a pathname to a restricted directory, leading to a path traversal condition...
