Oracle E-Business Suite Integrated SOA Gateway: Authorization flaw allows takeover
Summary
Oracle E-Business Suite Integrated SOA Gateway (SOA Provider component), versions 12.2.3 to 12.2.15, is affected. An attacker with a low-privileged account and network access via HTTP can compromise the component, with possible full takeover and impact on confidentiality, integrity and availability. No user interaction is required, but a valid EBS login is needed. Oracle lists the issue in its October 2026 Critical Patch Update.
Affected
- Oracle E-Business Suite Integrated SOA Gateway (SOA Provider), versions 12.2.3 to 12.2.15
- CVSS 3.1: 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)
Fixed in
- Fixed in the Oracle Critical Patch Update of October 2026 (published 20 October 2026)
- Patch IDs: Unknown. Obtain them from the Oracle advisory and My Oracle Support before rollout.
- No fixed version beyond the October 2026 CPU is known.
Workaround
- Unknown for this CVE.
- Generic, not vendor-verified: restrict access to the EBS web tier and SOA Gateway endpoints to trusted networks until patched.
Exploitation
- Exploited in the wild: nothing found for this CVE.
- Public proof of concept: nothing found.
- CISA KEV status: not verified.
- Separate: exploratory probing was reported against CVE-2026-101767 (Application Object Library), which is not this CVE.
Our recommendation
- Patch in the next maintenance window using the October 2026 CPU; obtain exact patch IDs from Oracle first.
- Apply the fix to test and clone instances as well.
- Check whether EBS web tier or SOA Gateway endpoints are reachable from the internet, including via partner or VPN paths, and restrict access until patched.
- Review EBS user accounts and monitor for unusual SOA Gateway requests.
- Check related CVE-2026-101685 and CVE-2026-101690 together.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
