Summary
Flowise: Cross-workspace credential IDOR in openai-assistants-vector-store
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.
Reproduction steps
- Set up two workspaces: A (attacker) and B (victim), each with an OpenAI credential.
- Log in as a user in workspace A (with assistants-related permissions).
- Call
/api/v1/openai-assistants-vector-storeand setcredentialto B’s credential ID. - Example:
GET /api/v1/openai-assistants-vector-store?credential=<B_credentialId>. - If responses/actions are executed using B’s credential context, the issue is confirmed.
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.
The application does not correctly enforce access controls, allowing a principal to access resources or operations beyond their granted permissions. Typical impact: unauthorized data access or execution of privileged operations.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2026-70472? CVE-2026-70472 is a high-severity incorrect authorization vulnerability in flowise (npm), affecting versions <= 3.1.2. It is fixed in 3.1.3. The application does not correctly enforce access controls, allowing a principal to access resources or operations beyond their granted permissions.
- Which versions of flowise are affected by CVE-2026-70472? flowise (npm) versions <= 3.1.2 is affected.
- Is there a fix for CVE-2026-70472? Yes. CVE-2026-70472 is fixed in 3.1.3. Upgrade to this version or later.
- Is CVE-2026-70472 exploitable, and should I be worried? Whether CVE-2026-70472 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2026-70472 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
