IBM Langflow OSS 1.0.0 through 1.11.5 could allow a remote attacker to execute arbitrary OS commands due to improper neutralization of special elements used in an OS command.
AnalysisAI
Remote OS command execution in IBM Langflow OSS (versions 1.0.0 through 1.11.5) lets remote attackers run arbitrary operating-system commands due to improper neutralization of special elements passed into a shell command (CWE-78). Per the CVSS vector (PR:N/UI:N), exploitation requires no authentication or user interaction and yields full confidentiality, integrity, and availability impact on the host. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Per the CVSS vector, no authentication (PR:N) and no user interaction (UI:N) are required, and the attack is network-reachable (AV:N) with low complexity (AC:L), implying remote unauthenticated exploitation against affected Langflow OSS 1.0.0-1.11.5 instances that expose the vulnerable command-handling endpoint. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine high-priority issue: the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, score 9.8) describes unauthenticated, low-complexity, network-reachable command execution with total host impact, and the CWE-78 class is highly automatable once a working request is known - so any organization running an internet-exposed Langflow instance should treat this as urgent. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the vendor patch: a fix is available per the IBM advisory at https://www.ibm.com/support/pages/node/7286666 - upgrade to the fixed Langflow OSS release identified there (an exact fixed version is not enumerated in the provided input, so confirm the target build from the advisory before upgrading). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify and inventory all systems running IBM Langflow OSS versions 1.0.0-1.11.5; assess whether any are internet-facing or accessible from untrusted networks. …
