Medium (6.0). EPSS 0.4% chance of exploitation in the next 30 days. Fixed in flowise 3.1.2.
Flowise before 3.1.2 contains a mass assignment vulnerability in the PUT /api/v1/user endpoint that allows authenticated users to directly modify the credential field without validation. Attackers can bypass password change verification and session invalidation by supplying a crafted password hash, establishing persistent account access after temporary session compromise.
