AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Network-reachable web app with low complexity and no user interaction; requires an authenticated session so PR:L; sandbox-escape RCE yields full C/I/A on the unchanged host scope.

IBM Langflow OSS 1.0.0 through 1.12.2 could allow a remote authenticated attacker to execute arbitrary code due to improper neutralization of special elements used in code, resulting in a sandbox escape.
AnalysisAI
Remote code execution in IBM Langflow OSS 1.0.0 through 1.12.2 lets an authenticated attacker escape the application's code execution sandbox and run arbitrary commands on the host. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N) confirms network reachability and a low-privileged authenticated session as the only precondition, with no user interaction required. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated session on the Langflow OSS web application (PR:L), so the instance must be reachable by the attacker and the attacker must possess or obtain a low-privileged account - this is the primary limiting factor and rules out fully anonymous mass exploitation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine prioritization concern rather than an inflated-CVSS artifact. … 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 described in IBM advisory node/7290694; the advisory is the authoritative source for the exact fixed version, which is not enumerated in the available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory every Langflow OSS deployment and identify instances running versions 1.0.0 through 1.12.2, prioritizing internet-exposed and multi-tenant installations; restrict network access to the Langflow UI and API to trusted IP ranges or a VPN as temporary containment, and audit for dormant, shared, or over-privileged accounts since a low-privileged login is the only precondition. …
