Flowise - Remote Code Execution via overrideConfig Parameter

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Published

Flowise before 2.1.4 allows configuration to be injected into the Chainflow during execution via the overrideConfig option, supported in both the frontend web integration and the backend Prediction API. Because this feature is enabled by default with no allow-list of permitted variables and relies on vm2 for sandboxing, an attacker can abuse it to achieve remote code execution and sandbox escape, denial of service by crashing the server, server-side request forgery, prompt injection, and server variable and data exfiltration. These issues are self-targeted and do not persist to other users.

### Impact Flowise allows developers to inject configuration into the Chainflow during execution through the `overrideConfig` option. This is supported in both the frontend web integration and the backend Prediction API. This has a range of fundamental issues that are a **major** security vulnerability. While this feature is intentional, it should have strong protections added and be disabled by default. These issues include: 1. Remote code execution. While inside a sandbox this allows for 1. Sandbox escape 2. DoS by crashing the server 3. SSRF 2. Prompt Injection, both System and User 1. Full control over LLM prompts 2. Server variable and data exfiltration And many many more such as altering the flow of a conversation, prompt exfiltration via LLM proxying etc. These issues are self-targeted and do not persist to other users but do leave the server and business exposed. All issues are shown with the API but also work with the web embed. ### Workarounds - `overrideConfig` should be disabled by default - `overrideConfig` should have an explicit allow list of variables that are allowed to be modified. This way the user opts-in to where modifications can be made. - `vm2` and any forks of it should be removed as in the authors own words, "fixing the vulnerability seems impossible". The recommended replacement is https://www.npmjs.com/package/isolated-vm
