7.5 (High) - CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H

CWE

CWE-502 - Deserialization of Untrusted Data

Summary

IBM Langflow OSS 1.0.0 through 1.12.2 could allow an attacker with access to the server secret and Redis write access to submit a malicious serialized cache value. When the value was retrieved, deserialization could have executed attacker-controlled code with the privileges of the service process.

CVE-2026-12944 (GCVE-0-2026-12944)

Vulnerability from cvelistv5

Published

2026-09-14 21:30

Modified

2026-09-16 03:56

Severity ?

9.6 (Critical) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N

CWE

CWE-918 - Server-Side Request Forgery (SSRF)

Summary

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.
