Unauthorized access and impersonation can occur in versions 4.6.2.3226 and below of Progress Software's Hybrid Data Pipeline Server on Linux. This vulnerability allows attackers to combine credentials from different sources, potentially leading to client impersonation and unauthorized access. When OAuth Clients perform an OAuth handshake with the Hybrid Data Pipeline Server, the server accepts client credentials from both HTTP headers and request parameters.
