CVE-2025-34267: CWE-77 Improper Neutralization of Special Elements used in a Command ('Command Injection') in FlowiseAI Flowise
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 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.
AI Analysis
Technical Summary
CVE-2025-34267 is a command injection vulnerability (CWE-77) affecting FlowiseAI's Flowise product. Versions 3.0.1 through before 3.0.8, and any version with 'ALLOW_BUILTIN_DEP' enabled, allow authenticated attackers to execute arbitrary code on the host system by leveraging Puppeteer and Playwright modules insecurely within the node VM sandbox. Attackers can specify attacker-controlled browser binary paths and parameters, which are executed on the host, escaping the intended sandbox restrictions. This vulnerability enables remote code execution with high impact on confidentiality, integrity, and availability. It is a separate issue from CVE-2025-26319.
Potential Impact
An authenticated attacker can achieve remote code execution on the host system by escaping the node VM sandbox through malicious use of Puppeteer and Playwright modules. This compromises the host's security, potentially allowing full control over the system, data exposure, and disruption of service. The vulnerability has a high CVSS 4.0 score of 8.4, indicating significant risk.
Mitigation Recommendations
No official patch or fix is currently confirmed or provided by the vendor. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict authenticated user capabilities to create or run tools that leverage Puppeteer or Playwright, and consider disabling the 'ALLOW_BUILTIN_DEP' option if possible to reduce exposure.
