DescriptionNVD

IBM Langflow OSS 1.0.0 through 1.11.2 could allow a remote authenticated attacker to obtain sensitive information due to server-side request forgery.

AnalysisAI

Server-side request forgery in IBM Langflow OSS 1.0.0 through 1.11.2 allows authenticated remote attackers to leverage the application server as a proxy to reach internal network resources, exposing sensitive information from systems not directly accessible to the attacker. The CVSS S:C scope-change metric signals that the primary risk extends beyond the vulnerable component itself - cloud-hosted instances are particularly exposed to metadata-service credential theft via endpoints like AWS IMDSv1. …
