AI Analysis
Technical Summary
CVE-2026-46477 affects FlowiseAI's Flowise product before version 3.1.2. The vulnerability arises from improper control over modification of dynamically-determined object attributes during dataset create and update operations. This mass-assignment flaw enables an attacker with limited privileges to take over datasets across different workspaces. The issue is classified under CWE-915 and has been addressed by the vendor in version 3.1.2.
Potential Impact
Exploitation of this vulnerability allows an attacker with some privileges to perform cross-workspace dataset takeover, potentially leading to unauthorized access or modification of datasets belonging to other workspaces. This could compromise data integrity and confidentiality within the affected Flowise installations.
Mitigation Recommendations
Upgrade Flowise to version 3.1.2 or later, where this vulnerability has been patched. Since this is not a cloud service, users must apply the update themselves. Patch status is confirmed by the vendor advisory indicating the fix in version 3.1.2.
