How to Fix CVE-2026-70472

To remediate this vulnerability, upgrade all affected Flowise dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

flowise fixed: 3.1.3 
npm install flowise@3.1.3
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls flowise

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-70472, inspect your project dependencies using npm:

npm ls flowise

Analyze the terminal output to locate any version of Flowise in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.1.3), your application is affected.

Note: The npm ls flowise command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-285: Improper Authorization, where the product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. In Flowise, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

# Summary These endpoints accept a client-controlled `credential` parameter. The server loads credentials by `id` and uses them directly, without checking whether that credential belongs to the caller’s workspace. If an attacker knows another workspace’s `credentialId`, they can use that workspace’s OpenAI key. # Details Route permissions (`assistants:*`) only check feature access. They do not check credential ownership. The controller passes `req.query.credential` straight to the service. The service does `findOneBy({ id: credentialId })`, decrypts the credential, and calls OpenAI APIs. There is no `workspaceId` check in this flow, so this is an IDOR. # Impact - Cross-workspace unauthorized use of stored OpenAI keys. - Unauthorized read/modify/delete of victim vector stores and files. - Direct billing impact on victim OpenAI account. - Multi-tenant boundary violation with practical exploitability. # Reproduction steps 1. Set up two workspaces: A (attacker) and B (victim), each with an OpenAI credential. 2. Log in as a user in workspace A (with assistants-related permissions). 3. Call `/api/v1/openai-assistants-vector-store` and set `credential` to B’s credential ID. 4. Example: `GET /api/v1/openai-assistants-vector-store?credential=<B_credentialId>`. 5. If responses/actions are executed using B’s credential context, the issue is confirmed.
