CVE-2026-8478 Details
Description
IBM Langflow OSS 1.0.0 through 1.10.3 could allow a remote attacker to inject arbitrary code on the system, due to the improper control of user input code.
A code injection vulnerability has been identified in IBM Langflow OSS versions 1.0.0 through 1.10.3. This vulnerability could allow remote attackers to execute arbitrary code on the system, stemming from inadequate control over user input code. The issue arises from weaknesses in code security scanning, runtime validation, and the execution of custom components, which could enable authenticated users to bypass restrictions or execute crafted Python code. Exploitation may lead to unauthorized actions in the Langflow process context, such as outbound network access, file system interaction, or data exfiltration, depending on the privileges of the Langflow backend process.
Users are advised to upgrade to IBM Langflow OSS version 1.11.0 or newer.
