CVE-2026-69252: CWE-862: Missing Authorization in FlowiseAI Flowise
FlowiseAI Flowise versions prior to 3.1.3 contain a missing authorization vulnerability in the /api/v1/files API endpoint. Low-privileged authenticated API keys with unrelated permissions could list and delete files across different workspaces within the same organization due to insufficient permission checks. This issue is resolved in version 3.1.3.
AI Analysis
Technical Summary
CVE-2026-69252 describes a missing authorization vulnerability (CWE-862) in FlowiseAI Flowise before version 3.1.3. The /api/v1/files route was only protected by a feature gate and did not enforce permission checks on GET or DELETE requests. As a result, an attacker with a low-privileged authenticated API key could list files under the organization storage root and delete files belonging to other workspaces by exploiting the lack of access restriction based on permissions or active workspace ID. The vulnerability is fixed in version 3.1.3.
Potential Impact
An attacker with a low-privileged authenticated API key can enumerate and delete files across different workspaces within the same organization, potentially leading to unauthorized data disclosure and data loss. This elevates the risk of data integrity and confidentiality breaches within affected deployments.
Mitigation Recommendations
Upgrade Flowise to version 3.1.3 or later, where this authorization issue has been fixed. Patch status is confirmed by the vendor advisory indicating the fix in 3.1.3. No alternative mitigations are specified.
