CVE-2026-62586Network attack vector

Unauthenticated data disclosure via undisclosed flaw

Published Aug 18, 2026 · Updated Aug 21, 2026

Improper access control in Data Archival in Oracle Siebel CRM Administration 25.12 through 26.6 allows remote attackers to read data via HTTP. Oracle's advisory and the NVD record identify the affected component, attack path, and confidentiality impact, but they do not disclose the request path, code-level locus, or specific access check that fails. No credentials or user interaction are required, and published scoring bounds the effect to unauthorized access to data that Siebel CRM Administration can expose, with scope-change potential to connected products.
