Client impersonation via mixed OAuth credential sources
Published Jul 29, 2025 · Updated Jul 29, 2025
Improper authentication in Progress DataDirect Hybrid Data Pipeline Server 4.6.2.3226 and earlier allows remote attackers to impersonate OAuth clients. During an OAuth handshake, the server accepts client credentials from both HTTP headers and request parameters instead of enforcing one authoritative source. An attacker who supplies a usable cross-source credential combination gains the access assigned to the impersonated client.
