CVE-2026-8056: CWE-94 Improper Control of Generation of Code ('Code Injection') in IBM Langflow OSS
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.
AI Analysis
Technical Summary
CVE-2026-8056 is a code injection vulnerability in IBM Langflow OSS versions 1.0.0 through 1.10.0. The issue arises from improper control of code generation in the apply_tweaks() function's parameter filtering mechanism, which allows authenticated users to override component parameters at runtime via the API. This can lead to execution of arbitrary code with high impact on confidentiality, integrity, and availability. The vulnerability is rated with a CVSS 3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). No known exploits in the wild have been reported, and no official patch or remediation level has been disclosed by IBM.
Potential Impact
Successful exploitation of this vulnerability could allow an authenticated user to execute arbitrary code by overriding component parameters at runtime, resulting in full compromise of the system's confidentiality, integrity, and availability. This could lead to unauthorized data access, modification, or service disruption within affected IBM Langflow OSS deployments.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict authenticated user access to trusted individuals only and monitor API usage for suspicious parameter overrides. Avoid exposing the vulnerable API to untrusted networks.
