The CVSS base score is 8.2 (High).
Affected
- Oracle Data Integrator 12.2.1.4.0
- Oracle Data Integrator 14.1.2.0.0
Fixed in
- Patches are listed in Oracle's October 2026 Critical Patch Update advisory (https://www.oracle.com/security-alerts/cpuoct2026.html). Patch numbers and fixed versions: Unknown. Check the revised advisory (Rev 2, 26 Oct 2026) risk matrix.
Workaround
- No CVE-specific workaround known.
- Restrict HTTP access to Oracle Data Integrator to management or application networks only (recommendation, not vendor guidance).
Exploitation
- Unknown. No exploitation reports, KEV listing or public proof of concept found as of 1 Nov 2026.
- CISA SSVC: Exploitation none, Automatable yes, Technical Impact partial.
Our recommendation
- Inventory all Oracle Data Integrator instances and check for versions 12.2.1.4.0 or 14.1.2.0.0.
- Check whether any ODI web or REST endpoint is reachable from the internet and remove that exposure if not needed.
- Apply the October 2026 Critical Patch Update for ODI from the revised Oracle advisory as a priority.
- Until patched, restrict network access to ODI and review web logs for unexpected requests.
- Re-check NVD and CISA KEV, as the NVD status is still Awaiting Analysis.
