CVE-2026-62587Network attack vector

Low-privilege data read/write via authorization 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 authenticated users to read and modify data over HTTP. Oracle's August 18, 2026 advisory and the published CVE/NVD records do not identify the affected endpoint, request, or failed authorization check, so the public mechanism is limited to an undisclosed authorization flaw in the Data Archival component. Exploitation requires network reachability and valid low-privilege credentials; published impact is bounded to access to all accessible administration data and update, insert, or delete access to some accessible data, with no stated availability impact.
