Summary
Flowise versions 3.0.1 through 3.0.8 and all later versions with 'ALLOW_BUILTIN_DEP' enabled contain an authenticated remote code execution vulnerability due to insecure use of Puppeteer and Playwright modules. An attacker can bypass the Node VM sandbox and execute arbitrary code on the host.
Risk Assessment
An attacker can gain full control over the Flowise server, execute arbitrary code in the host context, leading to system compromise, data theft, or further attacks on the infrastructure.
Recommendation
Immediately upgrade Flowise to version 3.0.8 or later and disable the 'ALLOW_BUILTIN_DEP' option if not required. Restrict access to tools using Puppeteer/Playwright to trusted users only.
Original NVD description (English source)
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.
