Exploitability

CWE

KEV

CWE ID	Description

Attack-Flow Graph

Executive Summary

This vulnerability in IBM Langflow OSS versions 1.0.0 through 1.10.3 allows a remote authenticated attacker to execute arbitrary code. The issue arises from improper limitation of a pathname to a restricted directory, which can be exploited to bypass intended access controls.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run malicious code on the affected system. This may lead to unauthorized access, data theft, or further compromise of the system and network. The impact depends on the system's role and the privileges of the compromised account.

Compliance Impact

This vulnerability could lead to unauthorized access and data breaches, which may violate compliance requirements such as GDPR or HIPAA. Organizations may face legal penalties, reputational damage, and loss of trust if such incidents occur due to inadequate security measures.

Mitigation Strategies

Update IBM Langflow OSS to a version beyond 1.10.3 to address the arbitrary code execution flaw. Ensure only authenticated users have access to the system and restrict directory access permissions.
