Severity by source
AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Network-accessible configuration interface with low-privilege authentication aligns with AV:N/PR:L; full C/I/A impact reflects arbitrary code execution capability on the host system.

IBM Langflow OSS 1.0.0 through 1.10.3 could allow a remote attacker to execute arbitrary code due to improper validation of configuration parameters.
AnalysisAI
Remote code execution in IBM Langflow OSS 1.0.0 through 1.10.3 allows authenticated remote attackers to run arbitrary commands by supplying crafted configuration parameters that bypass the application's incomplete input denylist (CWE-184). The flaw carries a CVSS 8.8 score with full confidentiality, integrity, and availability impact, and SSVC rates the technical impact as total. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires valid, low-privilege credentials to an IBM Langflow OSS instance (CVSS PR:L confirmed); purely unauthenticated exploitation is not supported by the available vector data. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) establishes a network-exploitable, low-complexity attack requiring only low-privilege authentication - a serious baseline. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with low-privilege authenticated access to an exposed IBM Langflow OSS 1.0.0-1.10.3 instance submits a crafted configuration parameter payload through the workflow configuration interface. The payload evades the application's incomplete denylist validation and is processed by a downstream code execution pathway, allowing the attacker to run arbitrary commands under the Langflow service account's operating system privileges. … |
| Remediation | The primary fix is to apply the IBM-released patch; consult the vendor advisory at https://www.ibm.com/support/pages/node/7282147 for the exact target version and upgrade instructions, as a specific fixed version number was not independently confirmed from the available intelligence data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all systems running IBM Langflow OSS versions 1.0.0 through 1.10.3 and assess whether they are accessible to untrusted authenticated users. …
