Summary

CVE-2025-34267 is a high-severity Command Injection (CWE-77) vulnerability in Flowiseai Flowise. Its CVSS base score is 8.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

This vulnerability is AI-related — categorised as LLM Application Platforms; in the Supply Chain and Deployment risk domain.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-34267 is an authenticated remote code execution vulnerability combined with a Node VM sandbox escape in Flowise, affecting versions from v3.0.1 up to but not including 3.0.8, as well as all subsequent versions where the 'ALLOW_BUILTIN_DEP' configuration option is enabled. The issue stems from insecure usage of the integrated Puppeteer and Playwright modules within the nodevm execution environment. These modules allow specification of attacker-controlled browser binary paths and parameters, which bypass the intended sandbox restrictions when a tool leveraging them is executed.

An authenticated attacker with the ability to create or run a tool that uses Puppeteer or Playwright can exploit this vulnerability remotely over the network with low complexity and no user interaction required. Successful exploitation results in arbitrary code execution on the host system in the context of the Flowise process, granting high confidentiality, integrity, and availability impacts, as reflected in the CVSS v3.1 base score of 9.9 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H). The vulnerability is linked to CWE-77 (Command Injection).

Mitigation details are available in the official Flowise security advisory (GHSA-5w3r-f6gm-c25w) and a related pull request (#5231) on the Flowise GitHub repository, along with analysis from VulnCheck. Note that developers initially misidentified this as a duplicate of CVE-2025-26319, but it is distinct. Security practitioners should review these resources for patching instructions and disable 'ALLOW_BUILTIN_DEP' where possible. FlowiseAI is a low-code platform for building LLM applications, making this relevant to AI/ML deployments.

Vulnerability Data

Flowise v3.0.1 < 3.0.8 and all versions after with 'ALLOW_BUILTIN_DEP' enabled contain an authenticated remote code execution vulnerability and node VM sandbox escape due to insecure use of integrated modules (Puppeteer and Playwright) within the nodevm execution environment. An authenticated…

more

attacker able to create or run a tool that leverages Puppeteer/Playwright can specify attacker-controlled browser binary paths and parameters. When the tool executes, the attacker-controlled executable/parameters are run on the host and circumvent the intended nodevm sandbox restrictions, resulting in execution of arbitrary code in the context of the host. This vulnerability was incorrectly assigned as a duplicate CVE-2025-26319 by the developers and should be considered distinct from that identifier.
