Affected
- Oracle JD Edwards EnterpriseOne Tools 9.2.0.0 to 9.2.26.5 (Enterprise Infrastructure SEC component)
Fixed in
- Oracle security patch released in the October 2026 Critical Patch Update (patch identifiers for 9.2.x: check the Oracle advisory, not verified here)
Workaround
- Unknown. The CVE record provides no vendor workaround.
- Generic hardening only (not vendor guidance): restrict access to the HTTP interface, use VPN or IP allowlisting, and require authentication.
Exploitation
- CISA KEV: not listed.
- EPSS: below 1% (very low).
- Public proof of concept: none found in research, which does not rule out existence.
- CISA SSVC: exploitation none, not automatable, total technical impact.
Our recommendation
- Apply the Oracle October 2026 Critical Patch Update to affected JD Edwards EnterpriseOne Tools versions.
- Check whether the JD Edwards HTTP interface is reachable from the internet; if so, treat as high priority.
- Restrict network access to the interface and review low-privileged accounts, including former-employee accounts.
- Check whether JD Edwards Orchestrator (CVE-2026-91299) is installed and patch it first if so.
- Monitor logs for unusual data changes or deletions.
