Oracle JD Edwards EnterpriseOne Tools: Unauthenticated access via HTTP (Object and Env Tech SEC)
Summary
A flaw in the Object and Env Tech SEC component of Oracle JD Edwards EnterpriseOne Tools allows an unauthenticated attacker with network access via HTTP to compromise the product. Because the scope changes, the attack may also significantly impact other connected products. A successful attack can lead to unauthorized access to critical data or to access to all data accessible by JD Edwards EnterpriseOne Tools; the CVSS base score is 8.6 (High) with a high confidentiality impact. No user interaction or login is required.
Affected
- Oracle JD Edwards EnterpriseOne Tools, versions 9.2.0.0 to 9.2.26.5
Fixed in
- Unknown. The fix is contained in Oracle's October 2026 Critical Patch Update; the exact patched version has not been confirmed.
Workaround
- Unknown. The CVE record provides no workaround. Restricting network access to the EnterpriseOne HTTP endpoints (allow-lists, VPN or reverse proxy) is a reasonable interim measure, but this is not confirmed by Oracle.
Exploitation
- CISA KEV: not listed.
- No public proof of concept or in-the-wild exploitation found as of research; not verified against vendor or researcher sources.
- CISA SSVC: exploitation none, automatable yes, technical impact partial.
Our recommendation
- Check whether the EnterpriseOne web tier (HTTP/HTTPS) is reachable from the internet or partner networks; if so, treat this as a priority.
- Obtain the exact patch from Oracle's October 2026 CPU advisory and apply it to all EnterpriseOne Tools 9.2 systems in scope.
- Until patched, restrict access to the EnterpriseOne HTTP endpoints to required hosts only.
- Monitor for public proof of concept or KEV listing and review web tier logs for unusual unauthenticated requests.
- Confirm the NVD record and any CISA or NCSC updates.
