Overview
flowise is a Flowiseai Server
Affected versions of this package are vulnerable to Incorrect Authorization in the OAuth2 credential handling process due to insufficient workspace scoping and authentication checks on the authorize, callback, and refresh endpoints. An attacker can access or manipulate OAuth2 credentials belonging to other workspaces by sending crafted requests to these endpoints. This allows unauthorized retrieval of credential metadata, injection of attacker-controlled tokens, and refreshing of tokens for any credential, potentially leading to unauthorized access to connected external services.
