IBM Langflow OSS 1.0.0 through 1.12.2 could allow a remote attacker to execute arbitrary code due to improper control of code generation.
AnalysisAI
Remote code execution in IBM Langflow OSS 1.0.0 through 1.12.2 allows attackers to execute arbitrary code via improper control of code generation (CWE-94). The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, base 9.8) indicates remote, unauthenticated, low-complexity exploitation with full confidentiality, integrity, and availability impact, though the independent assessment notes the pre-auth condition is not independently confirmed by the description. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to a Langflow OSS instance running an affected version (1.0.0 through 1.12.2) and the ability to send input into a code-generation path affected by improper code control (CWE-94). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine high-priority vulnerability on paper: the supplied CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, base 9.8) describes remote, unauthenticated, low-complexity code injection (CWE-94) yielding full confidentiality, integrity, and availability loss - the worst-case profile for an exposed service. … 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 | Patch available per vendor advisory at https://www.ibm.com/support/pages/node/7290694; since no exact fix version is provided in the input, consult the advisory for the specific patched release and upgrade all affected instances outside the 1.0.0-1.12.2 range. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all IBM Langflow OSS instances running versions 1.0.0 through 1.12.2, with priority on internet-exposed deployments, and apply the vendor patch referenced in the IBM advisory for CVE-2026-104334; if patching is not immediately possible, restrict network access to trusted IPs or isolate affected systems. …
