CVE-2026-3345: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in IBM Langflow Desktop
CVE-2026-3345 is a path traversal vulnerability in IBM Langflow Desktop version 1. 8. 4 and earlier. This flaw allows a remote attacker with limited privileges to send specially crafted URL requests containing directory traversal sequences (/.. /) to access arbitrary files on the affected system. The vulnerability has a CVSS score of 6. 5, indicating medium severity. There is no official patch or remediation level currently provided by the vendor. No known exploits are reported in the wild at this time.
AI Analysis
Technical Summary
IBM Langflow Desktop versions up to 1.8.4 contain a CWE-22 path traversal vulnerability that permits remote attackers with limited privileges to traverse directories outside the intended restricted directory by using specially crafted URL requests with dot-dot sequences (/../). This can lead to unauthorized disclosure of arbitrary files on the system. The vulnerability is network exploitable without user interaction and does not affect system integrity or availability. The CVSS 3.1 base score is 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N).
Potential Impact
Successful exploitation allows an attacker with limited privileges to read arbitrary files on the system, potentially exposing sensitive information. There is no impact on system integrity or availability. No known active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict network access to the affected application and monitor for suspicious requests containing directory traversal patterns. Avoid exposing the application to untrusted networks.
