CVE-2026-12944— Incomplete Security Scanner Blocklist Enables Network-Based Code Execution

Quick assessment

Affected
IBM Langflow OSS
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

IBM Langflow OSS 1.0.0 至 1.10.0 版本允许攻击者通过提交包含 或 导入的组件，在 Langflow 服务器上以 root 权限（UID=0）执行任意 Python 代码。这可能导致以下安全影响： (1) 通过 IMDSv1 SSRF 窃取 AWS 凭据，并获取具有完整 IAM 角色权限； (2) 从容器文件系统中外泄任意文件； (3) 在 Docker 网络内横向移动至内部服务（PostgreSQL、Redis）。 此外，扫描器错误地返回 ，提供了虚假的安全信号。

Vulnerability Title
Incomplete Security Scanner Blocklist Enables Network-Based Code Execution
Source: CVE Program / CVE List V5
Vulnerability Description
IBM Langflow OSS 1.0.0 through 1.10.0 can allow attackers to execute arbitrary Python code with root privileges (UID=0) on the Langflow server by submitting components containing socket or urllib imports. This enables: (1) AWS credential theft via IMDSv1 SSRF with full IAM role permissions, (2) arbitrary file exfiltration from the container filesystem, and (3) lateral movement to internal services (PostgreSQL, Redis) within the Docker network. The scanner incorrectly returns "validated": true, providing a false security signal.
