DescriptionCVE.org

IBM Langflow OSS 1.0.0 through 1.12.2 could allow a remote authenticated attacker to execute arbitrary code due to improper control of code generation.

AnalysisAI

Authenticated remote code execution affects IBM Langflow OSS 1.0.0 through 1.12.2, where improper control of code generation lets any account with at least low privileges (CVSS PR:L, AV:N, UI:N) cause attacker-supplied code to run server-side on the Langflow host, yielding high confidentiality, integrity, and availability impact (CVSS 8.8). Exploitation is not possible against a default install without valid credentials, and no public exploit code or confirmed active exploitation was identified at time of analysis. …

Vulnerability AssessmentAI

Exploitation Exploitation requires (1) network reachability to the Langflow OSS web service and (2) a valid authenticated account of at least low privilege (CVSS PR:L) - exploitation is NOT possible unauthenticated against a default install. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuine high-priority vulnerability, though not a drop-everything emergency. … 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 documented in IBM's advisory at https://www.ibm.com/support/pages/node/7290694; the input identifies a vendor patch as available but does not state an exact fixed version string, so the specific patched Langflow OSS build must be confirmed from that advisory rather than assumed, and any instance in the 1.0.0 through 1.12.2 range should be upgraded to a release above that window before routine use resumes. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, inventory every Langflow OSS deployment and flag any instance running versions 1.0.0 through 1.12.2, prioritizing internet-facing and multi-tenant systems; immediately restrict network access to those hosts to trusted networks or VPN-only, and disable self-registration or open low-privilege account provisioning unless it is business-critical. …
