CVE-2026-62442

Unauthorized data access and modification

Published Aug 18, 2026 · Updated Aug 20, 2026

Improper access control in Siebel Cloud Manager in Oracle Siebel CRM Cloud Applications 22.3 through 26.6 lets adjacent attackers read and modify data. Oracle has not published the vulnerable endpoint, code path, or validation failure in Siebel Cloud Manager, and the public CVE materials do not disclose the underlying mechanism beyond adjacent-network exposure. Exploitation does not require authentication or user interaction, but it does require access to the physical communication segment attached to the affected host; successful attacks can expose and alter application data, with no published indication of availability impact.
