CVE-2026-83085

Authenticated data exposure and modification

Published Sep 15, 2026 · Updated Sep 15, 2026

Data exposure and modification in Oracle Siebel CRM Cloud Applications 22.3 through 26.7 allows remote authenticated users to alter data. Oracle identifies the affected locus as Siebel Cloud Manager but does not disclose the operation that mishandles untrusted TCP input. Exploitation requires low-privileged access from the adjacent physical network segment and permits critical-data access, some data changes, and partial service interruption.
