2DescriptionCVE.org
Vulnerability in the Oracle Workflow product of Oracle E-Business Suite (component: Internal Operations). Supported versions that are affected are 12.2.3-12.2.15. Difficult to exploit vulnerability allows unauthenticated attacker with network access via SMTP to compromise Oracle Workflow. Successful attacks of this vulnerability can result in takeover of Oracle Workflow. CVSS 3.1 Base Score 8.1 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H).
AnalysisAI
Complete takeover of Oracle Workflow (a component of Oracle E-Business Suite, versions 12.2.3 through 12.2.15) is possible by a remote unauthenticated attacker who reaches the product over SMTP, per Oracle's July 2026 Critical Patch Update. The flaw is rated CVSS 8.1 with high confidentiality, integrity, and availability impact, but carries high attack complexity, meaning exploitation requires conditions outside the attacker's direct control. No public exploit identified at time of analysis and it is not listed in CISA KEV.
Technical ContextAI
Oracle Workflow is the embedded business-process automation and notification engine within Oracle E-Business Suite (EBS) 12.2, used to route approvals, alerts, and notifications, frequently via email over SMTP. The affected component is 'Internal Operations,' and the attack surface is the SMTP-based notification/mailer processing path, where inbound or crafted mail is parsed and acted upon by the Workflow engine. No CWE was assigned in the source data, and Oracle's advisory tags this as Information Disclosure; combined with the C:H/I:H/A:H vector and the 'takeover' language, the root cause class is not disclosed by Oracle but the impact is full compromise of the Workflow component. Exact affected products are Oracle Workflow 12.2.3-12.2.15 as shipped with Oracle EBS 12.2; no CPE strings were provided in the intelligence.
RemediationAI
Apply the patch delivered in the Oracle Critical Patch Update of July 2026 (https://www.oracle.com/security-alerts/cpujul2026.html); Oracle ships EBS fixes as CPU patch sets rather than a renamed product version, so identify and apply the specific 12.2 CPU patch for your EBS release - an exact standalone fix version was not provided in the input and should be taken directly from the Oracle advisory (Patch available per vendor advisory). Because the vector is SMTP-based, effective compensating controls until patching include restricting inbound SMTP connectivity to the EBS Workflow mailer to trusted mail relays only, placing the Workflow inbound mailer behind a filtering gateway, and disabling or tightly scoping the inbound (processing) Workflow mailer if inbound email actions are not required - with the trade-off that inbound email-based notification responses and approvals will stop functioning. Network-segment the EBS application tier so the SMTP listener is not reachable from untrusted networks. Do not rely on these controls as a permanent substitute for the CPU patch.
