CVE-2026-3341

IBM Langflow Desktop versions 1.0.0 through 1.8.4 allow an attacker to execute arbitrary commands with the privileges of the process running Langflow. This enables reading sensitive environment variables (API keys, DB credentials), modifying files, or launching further attacks on the internal network.

IBM Langflow Desktop <=1.8.4 allows a remote attacker to traverse directories on the system. An attacker could send a specially crafted URL request containing "dot dot" sequences (/../) to view arbitrary files on the system.

IBM Langflow Desktop versions 1.0.0 through 1.8.4 could allow an unauthenticated user to view other users' images due to an indirect object reference through a user-controlled key.

IBM Langflow Desktop versions 1.2.0 through 1.8.4 allow an authenticated attacker to traverse directories and write arbitrary files on the system via a crafted URL request containing /../ sequences.

IBM Langflow Desktop 1.6.0 through 1.8.4 is vulnerable to stored cross-site scripting. This vulnerability allows an authenticated user to embed arbitrary JavaScript code in the Web UI, thus altering the intended functionality and potentially leading to credentials disclosure within a trusted session.

IBM Langflow Desktop 1.0.0 through 1.8.4 is vulnerable to Server-Side Request Forgery (SSRF). An authenticated attacker may send unauthorized requests from the system, potentially leading to network enumeration or facilitating other attacks.

IBM Langflow Desktop versions 1.6.0 through 1.8.2 have a vulnerability that allows an authenticated user to execute arbitrary code on the system. This is due to an insecure default setting that permits deserialization of untrusted data in the FAISS component.
