CVE-2026-60357Network attack vector

Unauthenticated modification of synchronized integration data

Published Jul 21, 2026 · Updated Jul 21, 2026

Improper authentication in Oracle Siebel CRM Integration 17.0 through 26.5 allows remote attackers to modify synchronized data via HTTP. Oracle identifies Siebel Server Sync for Exchange but does not disclose which authentication check or request-handling operation fails. The published record does not identify the conditions that make exploitation difficult; unauthenticated network access permits update, insertion, or deletion of some accessible integration data without reported disclosure or service interruption.
