Summary

CVE-2026-8056 is a high-severity Code Injection (CWE-94) vulnerability in Langflow Langflow. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 22th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Vulnerability Data

IBM Langflow OSS 1.0.0 through 1.10.0 allows authenticated users to override component parameters at runtime via the API. A critical security flaw exists in the parameter filtering mechanism within the `apply_tweaks()` function.

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

T1059 Command and Scripting Interpreter Execution
Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries.

Why these techniques?

CWE-94 code injection in apply_tweaks() via unauthenticated API parameter override directly enables remote code execution on the Langflow server (T1190) and arbitrary command/script execution (T1059).

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly enforces validation of all API-supplied parameter values in apply_tweaks() to block the code-injection vectors that allow runtime overrides.

AC-3 Access Enforcement good match
prevent

Enforces the intended parameter-filtering policy so that authenticated users cannot bypass restrictions and arbitrarily override component settings via the API.

AC-6 Least Privilege partial match
prevent

Limits the privileges granted to authenticated users, reducing the set of component parameters they are permitted to modify at runtime.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

A.8.28 Secure coding partial match
prevents

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.

A.8.7 Protection against malware none match
none

Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
