Security readout for executives and security teams
Plain-English summary
Flowise deployments before 3.0.6 can let an unauthenticated remote attacker read files from the server. In default setups, this can expose the Flowise SQLite database, which may contain sensitive application data. The issue is high urgency where Flowise is internet-facing or handles customer, credential, or workflow data.
Executive priority
Prioritize remediation this week, or immediately for internet-facing Flowise. The business risk is sensitive data disclosure without login, not service disruption or code execution based on the provided evidence.
Technical view
The chatId parameter in two Flowise file-download endpoints is not validated before reaching streamStorageFile(). A fallback lookup path without orgId is evaluated after the storage containment check, enabling path traversal outside the intended storage directory. The reported impact is confidentiality loss only.
Likely exposure
Exposure is most likely in Flowise instances before 3.0.6, especially publicly reachable deployments using default local storage and SQLite paths. Internal-only instances still carry risk from unauthenticated network access.
Exploitation context
The source bundle does not cite active exploitation, and KEV status is false. The vulnerability is remotely reachable, requires no authentication, and has low attack complexity according to CVSS 4.0 scoring.
Researcher notes
Evidence supports CWE-73 external control of file path. The affected endpoints are /api/v1/get-upload-file and /api/v1/openai-assistants-file/download. Avoid assuming broader product impact beyond Flowise before 3.0.6.
Mitigation direction
- Upgrade Flowise to version 3.0.6 or later.
- Restrict network access to Flowise until the upgrade is complete.
- Review vendor advisory guidance for configuration-specific mitigations.
- Check whether sensitive data in Flowise storage or SQLite may be exposed.
- Rotate affected secrets if database or configuration exposure is suspected.
Validation and detection
- Inventory all Flowise deployments and confirm their running version.
- Check whether the affected endpoints are reachable without authentication.
- Review access logs for unusual file-download endpoint activity.
- Confirm upgraded systems no longer accept traversal-style chatId values.
- Assess whether default SQLite storage exists on affected hosts.

External Control of File Name or Path
External Control of File Name or Path represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
