Severity by source
AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Unauthenticated network-reachable OS command injection yields AV:N/AC:L/PR:N/UI:N; arbitrary code execution gives full C:H/I:H/A:H with S:U as the OS host is the vulnerable component.

IBM Langflow OSS 1.0.0 through 1.12.2 could allow a remote attacker to execute arbitrary code due to improper neutralization of special elements used in an OS command.
AnalysisAI
Unauthenticated remote code execution in IBM Langflow OSS 1.0.0 through 1.12.2 lets any attacker who can reach the service execute arbitrary operating system commands on the underlying host. Rated CVSS 3.1 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), the flaw requires no credentials, no user interaction, and no non-default configuration, so a default Langflow deployment exposed beyond localhost is directly exploitable. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to a Langflow OSS instance running an affected version (1.0.0 through 1.12.2); per the CVSS vector (AV:N/AC:L/PR:N/UI:N), no authentication, no user interaction, and no special non-default configuration are stated as prerequisites, so a default deployment exposed on the network is exploitable. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a high-priority issue backed by strong, internally consistent signals. … 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 fix referenced in the IBM advisory at https://www.ibm.com/support/pages/node/7290694 - patch availability is confirmed by the vendor, but the exact fixed build number is not stated in the available data, so upgrade to a release outside the affected 1.0.0 through 1.12.2 range as directed by that advisory rather than assuming any in-range version is fixed. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory every Langflow OSS deployment across the organization and determine which are running versions 1.0.0 through 1.12.2, prioritizing instances bound to non-localhost interfaces or otherwise reachable from untrusted networks; for any such instance that cannot be patched immediately, restrict access at the network layer (firewall rules, security groups, or reverse-proxy authentication) so only trusted operator addresses can connect. …
