Technical Analysis
CVE-2026-103360 describes a path traversal vulnerability in IBM Langflow OSS versions 1.0.0 through 1.12.2. The flaw arises from improper limitation of pathnames to restricted directories, enabling a remote attacker with authentication privileges to access sensitive files outside the intended directory scope. The vulnerability has a CVSS v3.1 base score of 8.1, reflecting high confidentiality and integrity impacts with network attack vector, low attack complexity, and no user interaction required.
Potential Impact
An authenticated remote attacker can exploit this vulnerability to obtain sensitive information by accessing files outside the intended restricted directories. This compromises confidentiality and integrity of data within the affected IBM Langflow OSS installations. There is no reported impact on availability.
Mitigation Recommendations
No patch or official remediation has been provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the affected versions and monitor for suspicious activity involving path traversal attempts.
