IBM Langflow OSS 1.0.0 through 1.11.1 could allow a remote attacker to obtain sensitive information and inject unauthorized messages due to a namespace collision between user identifiers.
CVE-2026-19294 1 Langflow 1 Langflow 2026-08-31 N/A 6.4 MEDIUM
IBM Langflow OSS 1.0.0 through 1.11.1 could allow a remote authenticated attacker to execute and read any user's private flow due to improper authorization.
CVE-2026-19875 4 Apple, Langflow, Linux and 1 more 4 Macos, Langflow, Linux Kernel and 1 more 2026-08-26 N/A 7.5 HIGH
IBM Langflow OSS 1.0.0 through 1.10.0 could allow a remote attacker to overwrite administrator email information and abuse the server as an outbound relay due to missing authentication for the registration endpoint.
CVE-2026-19297 4 Apple, Langflow, Linux and 1 more 4 Macos, Langflow, Linux Kernel and 1 more 2026-08-26 N/A 9.1 CRITICAL
IBM Langflow OSS 1.0.0 through 1.9.6 could allow a remote attacker to obtain unauthorized access to user accounts due to improper restriction of excessive authentication attempts.
CVE-2026-5027 1 Langflow 1 Langflow 2026-08-18 N/A 8.8 HIGH
The 'POST /api/v2/files' endpoint does not sanitize the 'filename' parameter from the multipart form data, allowing an attacker to write files to arbitrary locations on the filesystem using path traversal sequences ('../').
CVE-2026-17625 1 Langflow 1 Langflow 2026-08-06 N/A 7.2 HIGH
IBM Langflow OSS 1.0.0 through 1.10.3, 1.0.0 through 1.10.3, 1.0.0 through 1.10.3, 1.0.0 through 1.10.3, 1.0.0 through 1.10.3, 1.0.0 through 1.10.3, and 1.0.0 through 1.10.3 could allow a remote authenticated attacker to execute arbitrary commands due to improper neutralization of special elements used in an OS command.
CVE-2026-9077 1 Langflow 1 Langflow 2026-08-06 N/A 8.5 HIGH
IBM Langflow OSS 1.0.0 through 1.10.3 Langflow allows remote authenticated attackers to bypass localhost-only restrictions and write arbitrary MCP server configurations to IDE configuration files on the host system.
CVE-2026-10128 1 Langflow 1 Langflow 2026-08-06 N/A 6.5 MEDIUM
IBM Langflow OSS 1.0.0 through 1.10.3 allows authenticated users can exploit a built-in Langflow component to read arbitrary server environment variables, exposing sensitive secrets despite security controls intended to disable custom components.
CVE-2026-3357 1 Langflow 1 Langflow 2026-07-24 N/A 8.8 HIGH
IBM Langflow Desktop 1.6.0 through 1.8.2 Langflow could allow an authenticated user to execute arbitrary code on the system, caused by an insecure default setting which permits the deserialization of untrusted data in the FAISS component.
CVE-2026-0770 1 Langflow 1 Langflow 2026-07-22 N/A 9.8 CRITICAL
Langflow exec_globals Inclusion of Functionality from Untrusted Control Sphere Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Langflow. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the exec_globals parameter provided to the validate endpoint. The issue results from the inclusion of a resource from an untrusted control sphere. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-27325.
CVE-2026-5026 1 Langflow 1 Langflow 2026-06-17 N/A 5.4 MEDIUM
The '/api/v1/files/images/{flow_id}/{file_name}' endpoint serves SVG files with the 'image/svg+xml' content type without sanitizing their content. Since SVG files can contain embedded JavaScript, an attacker can upload a malicious SVG that executes arbitrary JavaScript when viewed by other users, leading to stored cross-site scripting (XSS). This allows stealing authentication tokens stored in cookies, including JWT access and refresh tokens.
CVE-2026-5025 1 Langflow 1 Langflow 2026-06-17 N/A 6.5 MEDIUM
The '/logs' and '/logs-stream' endpoints in the log router allow any authenticated user to read the full application log buffer. These endpoints only require basic authentication ('get_current_active_user') without any privilege checks (e.g., 'is_superuser').
CVE-2026-42048 1 Langflow 1 Langflow 2026-06-17 N/A 9.6 CRITICAL
Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to 1.9.0, Langflow is vulnerable to Path Traversal in the Knowledge Bases API (DELETE /api/v1/knowledge_bases). This occurs because user-supplied knowledge base names are concatenated directly into file paths without proper sanitization or boundary validation. An authenticated attacker can exploit this flaw to delete arbitrary directories anywhere on the server's filesystem, leading to data loss and potential service disruption. This vulnerability is fixed in 1.9.0.
CVE-2026-33873 1 Langflow 1 Langflow 2026-06-17 N/A 9.9 CRITICAL
Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to version 1.9.0, the Agentic Assistant feature in Langflow executes LLM-generated Python code during its validation phase. Although this phase appears intended to validate generated component code, the implementation reaches dynamic execution sinks and instantiates the generated class server-side. In deployments where an attacker can access the Agentic Assistant feature and influence the model output, this can result in arbitrary server-side Python execution. Version 1.9.0 fixes the issue.
CVE-2026-33497 1 Langflow 1 Langflow 2026-06-17 N/A 7.5 HIGH
Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to version 1.7.1, in the download_profile_picture function of the /profile_pictures/{folder_name}/{file_name} endpoint, the folder_name and file_name parameters are not strictly filtered, which allows the secret_key to be read across directories. Version 1.7.1 contains a patch.
