Un atacante autenticado capaz de crear o ejecutar una herramienta que aproveche Puppeteer/Playwright puede especificar rutas binarias y parámetros del navegador controlados por el atacante. Cuando la herramienta se ejecuta, el ejecutable/los parámetros controlados por el atacante se ejecutan en el host y eluden las restricciones de sandbox de nodevm previstas, lo que resulta en la ejecución de código arbitrario en el contexto del host. Esta vulnerabilidad fue asignada incorrectamente como un duplicado de CVE-2025-26319 por los desarrolladores y debe considerarse distinta de ese identificador."

vulnerability

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.
