CVE-2026-70926Network attack vector

Unauthenticated application takeover via SMTP

Published Aug 18, 2026 · Updated Aug 18, 2026

Vulnerability in Oracle Workflow in Oracle E-Business Suite 12.2.3 through 12.2.15 allows remote attackers to take over the application via SMTP. Oracle identifies Workflow Notification Mailer as the affected component but has not published the vulnerable function, parser, or input-handling mistake behind the SMTP attack path. Exposure requires attacker-reachable SMTP delivery to the mailer, and Oracle rates successful exploitation as full confidentiality, integrity, and availability compromise of Oracle Workflow.
